-# Work in progress release notes for Gluster 3.9.0 (RC1)
+# Release notes for Gluster 3.9.0
-These are the current release notes for Release Condidate 1. Follow up changes
-will add more user friendly notes and instructions.
+This is a major release that includes a huge number of changes. Many
+improvements contribute to better support of Gluster with containers and
+running your storage on the same server as your hypervisors. Lots of work has
+been done to integrate with other projects that are part of the Open Source
+storage ecosystem.
-The release-notes are being worked on by maintainers and the developers of the
-different features. Assistance of others is welcome! Contributions can be done
-in [this etherpad](https://public.pad.fsfe.org/p/glusterfs-3.9-release-notes).
+The most notable features and changes are documented on this page. A full list
+of bugs that has been addressed is included further below.
-(FIXME: insert useful release notes here)
+## Major changes and features
+
+### Introducing reset-brick command
+*Notes for users:*
+The reset-brick command provides support to reformat/replace the disk(s)
+represented by a brick within a volume. This is helpful when a disk goes bad etc
+
+Start reset process -
+```bash
+gluster volume reset-brick VOLNAME HOSTNAME:BRICKPATH start
+```
+The above command kills the respective brick process. Now the brick can be reformatted.
+
+To restart the brick after modifying configuration -
+```bash
+gluster volume reset-brick VOLNAME HOSTNAME:BRICKPATH HOSTNAME:BRICKPATH commit
+```
+If the brick was killed to replace the brick with same brick path, restart with following command -
+```bash
+gluster volume reset-brick VOLNAME HOSTNAME:BRICKPATH HOSTNAME:BRICKPATH commit force
+```
+
+*Limitations:*
+1. resetting a brick kills a brick process in concern. During this
+period the brick will not be available for IO's.
+2. Replacing a brick with this command will work only if both the brick paths
+are same and belong to same volume.
+
+### Get node level status of a cluster
+
+*Notes for users:*
+The get-state command provides node level status of a trusted storage pool from
+the point of view of glusterd in a parseable format. Using get-state command,
+external applications can invoke the command on all nodes of the cluster, and
+parse and collate the data obtained from all these nodes to get a complete
+picture of the state of the cluster.
+
+```bash
+# gluster get-state <glusterd> [odir <path/to/output/dir] [file <filename>]
+```
+This would dump data points that reflect the local state representation of the
+cluster as maintained in glusterd (no other daemons are supported as of now)
+to a file inside the specified output directory. The default output directory
+and filename is /var/run/gluster and glusterd_state_<timestamp> respectively.
+
+Following are the sections in the output:
+1. `Global`: UUID and op-version of glusterd
+2. `Global options`: Displays cluster specific options that have been set
+explicitly through the volume set command.
+3. `Peers`: Displays the peer node information including its hostname and
+connection status
+4. `Volumes`: Displays the list of volumes created on this node along with
+detailed information on each volume.
+5. `Services`: Displays the list of the services configured on this node along
+with their corresponding statuses.
+
+*Limitations:*
+1. This only supports glusterd.
+2. Does not provide complete cluster state. Data to be collated from all nodes
+by external application to get the complete cluster state.
+
+### Multi threaded self-heal for Disperse volumes
+*Notes for users:*
+Users now have the ability to configure multi-threaded self-heal in disperse volumes using the following commands:
+```bash
+Option below can be used to control number of parallel heals in SHD
+# gluster volume set <volname> disperse.shd-max-threads [1-64] # default is 1
+Option below can be used to control number of heals that can wait in SHD
+# gluster volume set <volname> disperse.shd-wait-qlength [1-65536] # default is 1024
+```
+
+### Hardware extention acceleration in Disperse volumes
+*Notes for users:*
+If the user has hardware that has special instructions which can be used in erasure code calculations on the client it will be automatically used. At the moment this support is added for cpu-extentions: `x64`, `sse`, `avx`
+
+### Lock revocation feature
+*Notes for users:*
+1. Motivation: Prevents cluster instability by mis-behaving clients causing bricks to OOM due to inode/entry lock pile-ups.
+2. Adds option to strip clients of entry/inode locks after N seconds
+3. Adds option to clear ALL locks should the revocation threshold get hit
+4. Adds option to clear all or granted locks should the max-blocked threshold get hit (can be used in combination w/ revocation-clear-all).
+5. Adds logging to indicate revocation event & reason
+6. Options are:
+```bash
+# gluster volume set <volname> features.locks-revocation-secs <integer; 0 to disable>
+# gluster volume set <volname> features.locks-revocation-clear-all [on/off]
+# gluster volume set <volname> features.locks-revocation-max-blocked <integer>
+```
+
+### On demand scrubbing for Bitrot Detection:
+*Notes for users:* With 'ondemand' scrub option, you don't need to wait for the scrub-frequency
+to expire. As the option name itself says, the scrubber can be initiated on demand to detect
+the corruption. If the scrubber is already running, this option is a no op.
+```bash
+# gluster volume bitrot <volume-name> scrub ondemand
+```
+ ### Improvements in Gluster NFS-Ganesha integration
+*Notes for users:*
+With this release the major change done is to store all the ganesha related configuration files in the shared storage volume mount point instead of having separate local copy in '/etc/ganesha' folder on each node.
+
+For new users, before enabling nfs-ganesha
+
+1. create a directory named *nfs-ganesha* in the shared storage mount point (*/var/run/gluster/shared_storage/*)
+
+2. Create *ganesha.conf* & *ganesha-ha.conf* in that directory with the required details filled in.
+
+For existing users, before starting nfs-ganesha service do the following :
+
+1. Copy all the contents of */etc/ganesha* directory (including *.export_added* file) to */var/run/gluster/shared_storage/nfs-ganesha* from any of the ganesha nodes
+
+2. Create symlink using */var/run/gluster/shared_storage/nfs-ganesha/ganesha.conf* on */etc/ganesha* one each node in ganesha-cluster
+
+3. Change path for each export entry in *ganesha.conf* file
+
+```sh
+Example: if a volume "test" was exported, then ganesha.conf shall have below export entry -
+ %include "/etc/ganesha/exports/export.test.conf" export entry.
+Change that line to
+ %include "/var/run/gluster/shared_storage/nfs-ganesha/exports/export.test.conf"
+```
+
+In addition, following changes have been made -
+* The entity "HA_VOL_SERVER= " in *ganesha-ha.conf* is no longer required.
+* A new resource-agent called portblock (available in >= *resource-agents-3.9.5* package) is added to the cluster configuration to speed up the nfs-client connections post IP failover or failback. This may be noticed while looking at the cluster configuration status using the command *pcs status*.
+
+### Availability of python bindings to libgfapi
+
+The official python bindings for GlusterFS libgfapi C library interface is
+mostly API complete. The complete API reference and documentation can be
+found at [libgfapi-python.rtfd.io](http://libgfapi-python.rtfd.io/)
+
+The python bindings have been packaged and has been made available over
+[PyPI](https://pypi.python.org/pypi/gfapi/).
+
+### Small file improvements in Gluster with md-cache (Experimental)
+*Notes for users:*
+With this release, metadata cache on the client side is integrated with the
+cache-invalidation feature so that the clients can cache longer without
+compromising on consistency. By enabling, the metadata cache and cache
+invalidation feature and extending the cache timeout to 600s, we have seen
+performance improvements in metadata operation like creates, ls/stat, chmod,
+rename, delete. The perf improvements is significant in SMB access of gluster
+volume, but as a cascading effect the improvements is also seen on FUSE/Native
+access and NFS access.
+
+Use the below options in the order mentioned, to enable the features:
+```bash
+ # gluster volume set <volname> features.cache-invalidation on
+ # gluster volume set <volname> features.cache-invalidation-timeout 600
+ # gluster volume set <volname> performance.stat-prefetch on
+ # gluster volume set <volname> performance.cache-invalidation on
+ # gluster volume set <volname> performance.cache-samba-metadata on # Only for SMB access
+ # gluster volume set <volname> performance.md-cache-timeout 600
+```
+
+### Real time Cluster notifications using Events APIs
+Let us imagine we have a Gluster monitoring system which displays
+list of volumes and its state, to show the realtime status, monitoring
+app need to query the Gluster in regular interval to check volume
+status, new volumes etc. Assume if the polling interval is 5 seconds
+then monitoring app has to run gluster volume info command ~17000
+times a day!
+
+With Gluster 3.9 release, Gluster provides close to realtime
+notification and alerts for the Gluster cluster state changes and
+alerts. Webhooks can be registered to listen to Events emitted by
+Gluster. More details about this new feature is available here.
+
+http://gluster.readthedocs.io/en/latest/Administrator%20Guide/Events%20APIs
+
+### Geo-replication improvements
+#### Documentation improvements:
+
+Upstream documentation is rewritten to reflect the latest version of
+Geo-replication. Removed the stale/duplicate documentation. We are
+still working on to add Troubleshooting, Cluster expand/shrink notes
+to it. Latest version of documentation is available here
+http://gluster.readthedocs.io/en/latest/Administrator%20Guide/Geo%20Replication
+
+#### Geo-replication Events are available for Events API consumers:
+Events APIs is the new Gluster feature available with 3.9 release,
+most of the events from Geo-replication are added to eventsapi.
+
+Read more about the Events APIs and Geo-replication events here
+http://gluster.readthedocs.io/en/latest/Administrator%20Guide/Events%20APIs
+
+#### New simplified command to setup Non root Geo-replication
+
+Non root Geo-replication setup was not easy with multiple manual
+steps. Non root Geo-replication steps are simplified. Read more about
+the new steps in Admin guide.
+
+http://gluster.readthedocs.io/en/latest/Administrator%20Guide/Geo%20Replication/#slave-user-setup
+
+#### New command to generate SSH keys(Alternative command to `gsec_create`)
+
+`gluster system:: execute gsec_create` command generates ssh keys in
+every Master cluster nodes and copies to initiated node. This command
+silently ignores error if any node is down in cluster. It will not
+collect SSH keys from that node. When Geo-rep create push-pem command
+is issued it will copy public keys from those nodes which were up
+during gsec_create. This causes Geo-rep to go to Faulty when that
+master node tries to make the connection to slave nodes. With the new
+command, output shows if any Master node was down while generating ssh
+keys. Read more about `gluster-georep-sshkey
+
+http://gluster.readthedocs.io/en/latest/Administrator%20Guide/Geo%20Replication/#setting-up-the-environment-for-geo-replication
+
+#### Logging improvements
+
+New logs are added, now from the log we can clearly understand what is
+going on. Note: This feature may change logging format of existing log
+messages, Please update your parsers if used to parse Geo-rep logs.
+
+Patch: http://review.gluster.org/15710
+
+#### New Configuration options available: changelog-log-level
+
+All the changelog related log messages are logged in
+`/var/log/glusterfs/geo-replication/<SESSION>/*.changes.log` in Master
+nodes. Log level was hard coded as `TRACE` for Changelog logs. New
+configuration option provided to modify the changelog log level and
+defaulted to `INFO`
+
+## Behavior changes
+- [#1221623](https://bugzilla.redhat.com/1221623): Earlier the ports GlusterD
+ used to allocate for the daemons like brick processes, quotad, shd et all
+ were persistent through the volume's life cycle, so every restart of the
+ process(es) or a node reboot will try to use the same ports which were
+ allocated for the first time. With release-3.9 onwards, GlusterD will try to
+ allocate a fresh port once a daemon is restarted or the node is rebooted.
+- [#1348944](https://bugzilla.redhat.com/1348944): with 3.9 release the default
+ log file for glusterd has been renamed to glusterd.log from
+ etc-glusterfs-glusterd.vol.log
+
+## Known Issues
+- [#1387878](https://bugzilla.redhat.com/1387878):add-brick on a vm-store
+ configuration which has sharding enabled is leading to vm corruption. To work
+ around this issue, one can scale up by creating more volumes until this issue
+ is fixed.

+ Multiple clients A, B and C are attempting 'mkdir -p /mnt/a/b/c'
+
+ 1 Client A is in the middle of mkdir(/a). It has acquired lock.
+ It has performed mkdir(/a) on one subvol, and second one is still
+ in progress
+ 2 Client B performs a lookup, sees directory /a on one,
+ ENOENT on the other, succeeds lookup.
+ 3 Client B performs lookup on /a/b on both subvols, both return ENOENT
+ (one subvol because /a/b does not exist, another because /a
+ itself does not exist)
+ 4 Client B proceeds to mkdir /a/b. It obtains entrylk on inode=/a with
+ basename=b on one subvol, but fails on other subvol as /a is yet to
+ be created by Client A.
+ 5 Client A finishes mkdir of /a on other subvol
+ 6 Client C also attempts to create /a/b, lookup returns ENOENT on
+ both subvols.
+ 7 Client C tries to obtain entrylk on on inode=/a with basename=b,
+ obtains on one subvol (where B had failed), and waits for B to unlock
+ on other subvol.
+ 8 Client B finishes mkdir() on one subvol with GFID-1 and completes
+ transaction and unlocks
+ 9 Client C gets the lock on the second subvol, At this stage second
+ subvol already has /a/b created from Client B, but Client C does not
+ check that in the middle of mkdir transaction
+ 10 Client C attempts mkdir /a/b on both subvols. It succeeds on
+ ONLY ONE (where Client B could not get lock because of
+ missing parent /a dir) with GFID-2, and gets EEXIST from ONE subvol.
+ This way we have /a/b in GFID mismatch. One subvol got GFID-1 because
+ Client B performed transaction on only one subvol (because entrylk()
+ could not be obtained on second subvol because of missing parent dir --
+ caused by premature/speculative succeeding of lookup() on /a when locks
+ are detected). Other subvol gets GFID-2 from Client C because while
+ it was waiting for entrylk() on both subvols, Client B was in the
+ middle of creating mkdir() on only one subvol, and Client C does not
+ "expect" this when it is between lock() and pre-op()/op() phase of the
+ transaction.

+ * Problem:
+ * While a brick is down in a replica pair, lets say the user creates
+ * one file(file-A) and a hard link to that file(h-file-A). After the
+ * brick comes back up, entry self-heal is attempted on parent dir of
+ * these two files. As part of readdir in self-heal it reads both the
+ * entries file-A and h-file-A for both of them it does name less lookup
+ * to check if there are any hardlinks already present in the
+ * destination brick. It finds that there are no hard links already
+ * present for files file-A, h-file-A. Self-heal does mknods for both
+ * file-A and h-file-A. This leads to file-A and h-file-A not being
+ * hardlinks anymore.
+ *
+ * Fix: (More like shrinking of race-window, the race itself is still
+ * present in posix-mknod).
+ * If mknod comes with the presence of GLUSTERFS_INTERNAL_FOP_KEY then
+ * posix_mknod checks if there are already any gfid-links and does
+ * link() instead of mknod. There still can be a race where two
+ * posix_mknods same gfid see that
+ * gfid-link file is not present and proceeds with mknods and result in

+ to get notified when the write became "stable".

+ fsync() acknowledgement before initiating the hard POST-OP.

+ part of the FOP itself. The same holds true for NFS stable

+ * cblock (or cipher block). A logical unit in a file.
+ * cblock size is defined as the number of bits
+ * in an input (or output) block of the block
+ * cipher (*). Cipher block size is a property of
+ * cipher algorithm. E.g. cblock size is 64 bits
+ * for DES, 128 bits for AES, etc.
+ *
+ * atomic cipher A cipher algorithm, which requires some chunks of
+ * algorithm text to be padded at left and(or) right sides before
+ * cipher transaform.
+ *
+ *
+ * block (atom) Minimal chunk of file's data, which doesn't require
+ * padding. We'll consider logical units in a file of
+ * block size (atom size).
+ *
+ * cipher algorithm Atomic cipher algorithm, which requires the last
+ * with EOF issue incomplete cblock in a file to be padded with some
+ * data (usually zeros).
+ *
+ *
+ * operation, which reading/writing from offset, which is not aligned to
+ * forms a gap at to atom size
+ * the beginning
+ *
+ *
+ * operation, which reading/writing count bytes starting from offset off,
+ * forms a gap at so that off+count is not aligned to atom_size
+ * the end
+ *
+ * head block the first atom affected by an operation, which forms
+ * a gap at the beginning, or(and) at the end.
+ * Сomment. Head block has at least one gap (either at
+ * the beginning, or at the end)
+ *
+ *
+ * tail block the last atom different from head, affected by an
+ * operation, which forms a gap at the end.
+ * Сomment: Tail block has exactly one gap (at the end).
+ *
+ *
+ * partial block head or tail block
+ *
+ *
+ * full block block without gaps.

+ * timelines.
+ *
+ * Basically, the contention is between multiple execution threads of this
+ * routine and the roll-over thread. So, instead of having a big lock, we hold
+ * granular locks: inode->lock and priv->lock. Now I'll explain what happens
+ * when there is an update and a roll-over at just about the same time.
+ * NOTE:
+ * - the dispatcher itself synchronizes updates via it's own lock
+ * - the slice version in incremented by the roll-over thread
+ *
+ * Case 1: When the rollover thread wins before the inode version can be
+ * compared with the slice version.
+ *
+ * [updater] | [rollover]
+ * |
+ * | <SLICE: 1, 1, 1>
+ * <changelog_update> |
+ * <changelog_inode_ctx_get> |
+ * <CTX: 1, 1, 1> |
+ * | <dispatch-rollover-event>
+ * | LOCK (&priv->lock)
+ * | <SLICE_VERSION_UPDATE>
+ * | <SLICE: 2, 2, 2>
+ * | UNLOCK (&priv->lock)
+ * |
+ * LOCK (&priv->lock) |
+ * <INODE_VERSION_EQUALS_SLICE> |
+ * I: 1 <-> S: 2 |
+ * update: true |
+ * UNLOCK (&priv->lock) |
+ * |
+ * <if update == true> |
+ * <dispath-update-event> |
+ * <INODE_VERSION_UPDATE> |
+ * LOCK (&inode->lock) |
+ * LOCK (&priv->lock) |
+ * <CTX: 2, 1, 1> |
+ * UNLOCK (&priv->lock) |
+ * UNLOCK (&inode->lock) |
+ *
+ * Therefore, the change gets recorded in the next change (no lost change). If
+ * the slice version was ahead of the inode version (say I:1, S: 2), then
+ * anyway the comparison would result in a update (I: 1, S: 3).
+ *
+ * If the rollover time is too less, then there is another contention when the
+ * updater tries to bring up inode version to the slice version (this is also
+ * the case when the roll-over thread wakes up during INODE_VERSION_UPDATE.
+ *
+ * <CTX: 1, 1, 1> | <SLICE: 2, 2, 2>
+ * |
+ * |
+ * <dispath-update-event> |
+ * <INODE_VERSION_UPDATE> |
+ * LOCK (&inode->lock) |
+ * LOCK (&priv->lock) |
+ * <CTX: 2, 1, 1> |
+ * UNLOCK (&priv->lock) |
+ * UNLOCK (&inode->lock) |
+ * | <dispatch-rollover-event>
+ * | LOCK (&priv->lock)
+ * | <SLICE_VERSION_UPDATE>
+ * | <SLICE: 3, 3, 3>
+ * | UNLOCK (&priv->lock)
+ *
+ *
+ * Case 2: When the fop thread wins
+ *
+ * [updater] | [rollover]
+ * |
+ * | <SLICE: 1, 1, 1>
+ * <changelog_update> |
+ * <changelog_inode_ctx_get> |
+ * <CTX: 0, 0, 0> |
+ * |
+ * LOCK (&priv->lock) |
+ * <INODE_VERSION_EQUALS_SLICE> |
+ * I: 0 <-> S: 1 |
+ * update: true |
+ * UNLOCK (&priv->lock) |
+ * | <dispatch-rollover-event>
+ * | LOCK (&priv->lock)
+ * | <SLICE_VERSION_UPDATE>
+ * | <SLICE: 2, 2, 2>
+ * | UNLOCK (&priv->lock)

+ * LOCK (&inode->lock) |
+ * LOCK (&priv->lock) |
+ * <CTX: 2, 0, 0> |
+ * UNLOCK (&priv->lock) |
+ * UNLOCK (&inode->lock) |
+ *
+ * Here again, if the inode version was equal to the slice version (I: 1, S: 1)
+ * then there is no need to record an update (as the equality of the two version
+ * signifies an update was recorded in the current time slice).

+This is just the very start for a GlusterFS[1] meta-translator that will
+allow translator code to be written in Python. It's based on the standard
+Python embedding (not extending) techniques, plus a dash of the ctypes module.
+The interface is a pretty minimal adaptation of the dispatches and callbacks
+from the C API[2] to Python, as follows:
+
+* Dispatch functions and callbacks must be defined on an "xlator" class
+ derived from gluster.Translator so that they'll be auto-registered with
+ the C translator during initialization.
+
+* For each dispatch or callback function you want to intercept, you define a
+ Python function using the xxx\_fop\_t or xxx\_cbk\_t decorator.
+
+* The arguments for each operation are different, so you'll need to refer to
+ the C API. GlusterFS-specific types are used (though only loc\_t is fully
+ defined so far) and type correctness is enforced by ctypes.
+
+* If you do intercept a dispatch function, it is your responsibility to call
+ xxx\_wind (like STACK\_WIND in the C API but operation-specific) to pass
+ the request to the next translator. If you do not intercept a function, it
+ will default the same way as for C (pass through to the same operation with
+ the same arguments on the first child translator).
+
+* If you intercept a callback function, it is your responsibility to call
+ xxx\_unwind (like STACK\_UNWIND\_STRICT in the C API) to pass the request back
+ to the caller.
+
+So far only the lookup and create operations are handled this way, to support
+the "negative lookup" example. Now that the basic infrastructure is in place,
+adding more functions should be very quick, though with that much boilerplate I
+might pause to write a code generator. I also plan to add structure
+definitions and interfaces for some of the utility functions in libglusterfs
+(especially those having to do with inode and fd context) in the fairly near
+future. Note that you can also use ctypes to get at anything not explicitly
+exposed to Python already.
+
+_If you're coming here because of the Linux Journal article, please note that
+the code has evolved since that was written. The version that matches the
+article is here:_

+'test.vol' is a simple volfile with the debug-trace Python translator on top

+$ glusterfs --debug -f test.vol /path/to/mntpt

+If then file operations are performed on the newly mounted file system, log

-gsycnd, the Gluster Syncdaemon
-==============================
-
-REQUIREMENTS
-------------
-
-_gsyncd_ is a program which can operate either in _master_ or in _slave_ mode.
-Requirements are categorized according to this.
-
-* supported OS is GNU/Linux
-* Python >= 2.5, or 2.4 with Ctypes (see below) (both)
-* OpenSSH >= 4.0 (master) / SSH2 compliant sshd (eg. openssh) (slave)
-* rsync (both)
-* glusterfs with marker support (master); glusterfs (optional on slave)
-* FUSE; for supported versions consult glusterfs
-
-INSTALLATION
-------------
-
-As of now, the supported way of operation is running from the source directory.
-
-If you use Python 2.4.x, you need to install the [Ctypes module](http://python.net/crew/theller/ctypes/).
-
-CONFIGURATION
--------------
-
-gsyncd tunables are a subset of the long command-line options; for listing them,
-type
-
- gsyncd.py --help
-
-and see the long options up to "--config-file". (The leading double dash should be omitted;
-interim underscores and dashes are interchangeable.) The set of options bear some resemblance
-to those of glusterfs and rsync.
-
-The config file format matches the following syntax:
-
- <option1>: <value1>
- <option2>: <value2>
- # comment
-
-By default (unless specified by the option `-c`), gsyncd looks for config file at _conf/gsyncd.conf_
-in the source tree.
-
-USAGE
------
-
-gsyncd is a utilitly for continous mirroring, ie. it mirrors master to slave incrementally.
-Assume we have a gluster volume _pop_ at localhost. We try to set up the following mirrors
-for it with gysncd:
-
-1. _/data/mirror_
-2. local gluster volume _yow_
-3. _/data/far_mirror_ at example.com
-4. gluster volume _moz_ at example.com
-
-The respective gsyncd invocations are (demoing some syntax sugaring):
-
-1.
-
- gsyncd.py gluster://localhost:pop file:///data/mirror
-
- or short form
-
- gsyncd.py :pop /data/mirror
-
-2. `gsyncd :pop :yow`
-3.
-
- gsyncd.py :pop ssh://example.com:/data/far_mirror
-
- or short form
-
- gsyncd.py :pop example.com:/data/far_mirror
-
-4. `gsyncd.py :pop example.com::moz`
-
-gsyncd has to be available on both sides; it's location on the remote side has to be specified
-via the "--remote-gsyncd" option (or "remote-gsyncd" config file parameter). (This option can also be
-used for setting options on the remote side, although the suggested mode of operation is to
-set parameters like log file / pid file in the configuration file.)

-
- Recursively walk the master side tree and check if updates are
- needed due to xtime differences. One invocation of crawl checks
- children of @path and do a recursive enter only on
- those directory children where there is an update needed.
-
- Way of updates depend on file type:
- - for symlinks, sync them directy and synchronously
- - for regular children, register jobs for @path (cf. .add_job) to start
- and wait on their rsync
- - for directory children, register a job for @path which waits (.wait)
- on jobs for the given child
- (other kind of filesystem nodes are not considered)
-
- Those slave side children which do not exist on master are simply
- purged (see Server.purge).
-
- Behavior is fault tolerant, synchronization is adaptive: if some action fails,
- just go on relentlessly, adding a fail job (see .add_failjob) which will prevent
- the .sendmark on @path, so when the next crawl will arrive to @path it will not
- see it as up-to-date and will try to sync it again. While this semantics can be
- supported by funky design principles (http://c2.com/cgi/wiki?LazinessImpatienceHubris),
- the ultimate reason which excludes other possibilities is simply transience: we cannot
- assert that the file systems (master / slave) underneath do not change and actions
- taken upon some condition will not lose their context by the time they are performed.

+ * The enumerated type here
+ * is used to index two kind
+ * of integer arrays:
+ * - gauges
+ * - counters
+
+ * A counter is used internally,
+ * in getxattr callbacks, to count
+ * the results, categorized as
+ * the enum names suggest. So values
+ * in the counter are always non-negative.
+
+ * Gauges are part of the API.
+ * The caller passes one to the
+ * top-level aggregator function,
+ * cluster_getmarkerattr(). The gauge
+ * defines an evaluation policy for the
+ * counter. That is, at the
+ * end of the aggregation process
+ * the gauge is matched against the
+ * counter, and the policy
+ * represented by the gauge decides
+ * whether to return with success or failure,
+ * and in latter case, what particular failure
+ * case (errno).
+
+ * The rules are the following: for some index i,
+ * - if gauge[i] == 0, no requirement is set
+ * against counter[i];
+ * - if gauge[i] > 0, counter[i] >= gauge[i]
+ * is required;
+ * - if gauge[i] < 0, counter[i] < |gauge[i]|
+ * is required.
+
+ * If the requirement is not met, then i is mapped
+ * to the respective errno (MCNT_ENOENT -> ENOENT),
+ * or in lack of that, EINVAL.
+
+ * Cf. evaluate_marker_results() and marker_idx_errno_map[]
+ * in libxlator.c
+
+ * We provide two default gauges, one inteded for xtime
+ * aggregation, other for volume mark aggregation. The
+ * policies they represent agree with the hard-coded
+ * one prior to gauges. Cf. marker_xtime_default_gauge
+ * and marker_uuid_default_gauge in libxlator.c

-/* dispatch table for VOLUME SET
- * -----------------------------
- *
- * Format of entries:
- *
- * First field is the <key>, for the purpose of looking it up
- * in volume dictionary. Each <key> is of the format "<domain>.<specifier>".
- *
- * Second field is <voltype>.
- *
- * Third field is <option>, if its unset, it's assumed to be
- * the same as <specifier>.
- *
- * Fourth field is <value>. In this context they are used to specify
- * a default. That is, even the volume dict doesn't have a value,
- * we procced as if the default value were set for it.
- *
- * Fifth field is <doctype>, which decides if the option is public and available
- * in "set help" or not. "NODOC" entries are not part of the public interface
- * and are subject to change at any time. This also decides if an option is
- * global (apllies to all volumes) or normal (applies to only specified volume).
- *
- * Sixth field is <flags>.
- *
- * Seventh field is <op-version>.
- *
- * There are two type of entries: basic and special.
- *
- * - Basic entries are the ones where the <option> does _not_ start with
- * the bang! character ('!').
- *
- * In their case, <option> is understood as an option for an xlator of
- * type <voltype>. Their effect is to copy over the volinfo->dict[<key>]
- * value to all graph nodes of type <voltype> (if such a value is set).
- *
- * You are free to add entries of this type, they will become functional
- * just by being present in the table.
- *
- * - Special entries where the <option> starts with the bang!.
- *
- * They are not applied to all graphs during generation, and you cannot
- * extend them in a trivial way which could be just picked up. Better
- * not touch them unless you know what you do.
- *
- *
- * Another kind of grouping for options, according to visibility:
- *
- * - Exported: one which is used in the code. These are characterized by
- * being used a macro as <key> (of the format VKEY_..., defined in
- * glusterd-volgen.h
- *
- * - Non-exported: the rest; these have string literal <keys>.
- *
- * Adhering to this policy, option name changes shall be one-liners.

+/* dispatch table for VOLUME SET
+ * -----------------------------
+ *
+ * Format of entries:
+ *
+ * First field is the <key>, for the purpose of looking it up
+ * in volume dictionary. Each <key> is of the format "<domain>.<specifier>".
+ *
+ * Second field is <voltype>.
+ *
+ * Third field is <option>, if its unset, it's assumed to be
+ * the same as <specifier>.
+ *
+ * Fourth field is <value>. In this context they are used to specify
+ * a default. That is, even the volume dict doesn't have a value,
+ * we procced as if the default value were set for it.
+ *
+ * Fifth field is <doctype>, which decides if the option is public and available
+ * in "set help" or not. "NO_DOC" entries are not part of the public interface
+ * and are subject to change at any time. This also decides if an option is
+ * global (apllies to all volumes) or normal (applies to only specified volume).
+ *
+ * Sixth field is <flags>.
+ *
+ * Seventh field is <op-version>.
+ *
+ * Eight field is description of option: If NULL, tried to fetch from
+ * translator code's xlator_options table.
+ *
+ * Nineth field is validation function: If NULL, xlator's option specific
+ * validation will be tried, otherwise tried at glusterd code itself.
+ *
+ * There are two type of entries: basic and special.
+ *
+ * - Basic entries are the ones where the <option> does _not_ start with
+ * the bang! character ('!').
+ *
+ * In their case, <option> is understood as an option for an xlator of
+ * type <voltype>. Their effect is to copy over the volinfo->dict[<key>]
+ * value to all graph nodes of type <voltype> (if such a value is set).
+ *
+ * You are free to add entries of this type, they will become functional
+ * just by being present in the table.
+ *
+ * - Special entries where the <option> starts with the bang!.
+ *
+ * They are not applied to all graphs during generation, and you cannot
+ * extend them in a trivial way which could be just picked up. Better
+ * not touch them unless you know what you do.
+ *
+ *
+ * Another kind of grouping for options, according to visibility:
+ *
+ * - Exported: one which is used in the code. These are characterized by
+ * being used a macro as <key> (of the format VKEY_..., defined in
+ * glusterd-volgen.h
+ *
+ * - Non-exported: the rest; these have string literal <keys>.
+ *
+ * Adhering to this policy, option name changes shall be one-liners.
