Execute all quota sub-commands on the volume except 'enable' and 'disable' and verify that the pid of quota daemon doesn't change. c. Stop the volume and verify that quotad is stopped. d. Start it again. Quotad must be started now. e. Create, start and enable quota on a second volume, verify that the pid of quotad changes on both the nodes (indicating a restart). f. Disable quota on one of the volumes and verify that quotad's pid changes. g. Disable quota on the second volume too and verify that quotad is stopped on both the nodes. h. Enable quota again on one of the volumes, and verify that quotad is started on both the nodes. i. Add a new node into this cluster and verify that quotad is spawned on this node too.

* features/quota: Improvements to quotaVarun Shastry2013-08-1210-249/+1117
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Old implementation * Client side implementation of quota - Not secure - Increased traffic in updating the ctx New Implementation * 2 stages of quota implementation is done: Soft and hard quota Upon reaching soft quota limit on the directory it logs/alerts in the quota daemon log (ie DEFAULT_LOG_DIR/quotad.log) and no more writes allowed after hard quota limit. After reaching the soft-limit the daemon alerts the user/admin repeatively for every 'alert-time', which is configurable. * Quota is moved to server-side. There will be 2 quota xlators i. Quota Server It takes care of the enforcing the quota and maintains the context specific to the brick. Since this doesn't have the complete picture of the cluster, cluster wide usage is updated from the quota daemon. This updated context is saved and used for the enforcement. It updates its context by searching the QUOTA_UPDATE_KEY from the dict in the setxattr call, and is updated from nowhere else. The quota is always loaded in the server graph and is by passed if the feature is not enabled. Options specific to quota-server: server-quota - Specifies whether the features is on/off. It is used to by pass the quota if turned off. deem-statfs - If set to on, it takes quota limits into consideration while estimating fs size. (df command) ii. Quota Daemon This is the new xlator introduced with this patch. Its the *gluster client* process with no mount point, started upon enabling quota or restarting the volume. This is a single process for all the volumes in the cluster. Its volfile stored in GLUSTERD_DEFAULT_WORKI_DIR/quotad/quotad.vol. It queries for the sizes on all the bricks, aggregates the size and sends back the updated size, periodically. The timeout between successive updation is configurable and typically/by default more for below-soft-quota usage and less for above-soft-quota usage. It maintains the timeout inside the limit structure based on the usage; below soft limit and above soft limit. There will be thread running per volume which iterates through the list and decides whether the size to be queried in the current iteration based on its timeout. It takes the next iteration time taking the least of the timeouts in the list of entries. Maintains a separate inode table for each volume in the quotad. In the first iteration it builds the table for quota-dirs (dirs on which limit is set) and its components. Options specific to quotad: hard-timeout - Timeout for updation of usage to the quota-server when the usage is crosses the soft-limit. soft-timeout - Timeout for the updation of usage to the quota-server when the usage is below soft-limit. alert-time - Frequency of logging after the usage reached soft limit. Options common to both: default-soft-limit - This is used when individual paths are not configured with soft-limit and default value of this option is 90% of the hard-limit. limit-set - String containing all the limits. Thus in the current implementation we'll have 2 quota xlators: one in server graph and one in trusted client (quota daemon) of which the sole purpose will be to aggregate the quota size xattrs from all the bricks and send the same to server quota xlator. * Changes in glusterd and CLI A single volfile is created for all the volumes, similar to nfs volfile. All files related to quota client (volfile, pid etc) are stored in GLUSTERD_DEFAULT_WORK_DIR/quotad/. The new pattern of the quota limit stores in limit-set = <single-dir-limit>[,<single-dir-limit>] single-dir-limit = <abs-path>:<hard-limit>[:<soft-limit-in-percent>] It also introduces new options: volume quota <VOLNAME> {enable|disable|list [<path> ...]|remove <path>| default-soft-limit <percent>} | volume quota <VOLNAME> {limit-usage <path> <size> |soft-limit <path> <percent>} | volume quota <VOLNAME> {alert-time|soft-timeout|hard-timeout} {<time>} Credit: Raghavendra Bhat <rabhat@redhat.com> Varun Shastry <vshastry@redhat.com> Shishir Gowda <sgowda@redhat.com> Kruthika Dhananjay <kdhananj@redhat.com> Brian Foster <bfoster@redhat.com> Krishnan Parthasarathi <kparthas@redhat.com> Change-Id: I16ec5be0c2faaf42b14034b9ccaf17796adef082 BUG: 969461 Signed-off-by: Varun Shastry <vshastry@redhat.com>

* storage/posix: implement batched fsync in a single threadAnand Avati2013-07-231-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because of the extra fsync()s issued by AFR transaction, they could potentially "clog" all the io-threads denying unrelated operations from making progress. This patch assigns a dedicated thread to issues fsyncs, as an experimental feature to understand performance characteristics with the approach. As a basis, incoming individual fsync requests are grouped into batches, falling in the same @batch-fsync-delay-usec window of time. These windows can extend in practice, as processing of the previous batch can take longer than @batch-fsync-delay-usec while new requests are getting batched. The feature support three modes (similar to the -S modes of fs_mark) - syncfs: In this mode one syncfs() is issued per batch, instead of N fsync()s (one per file.) - syncfs-single-fsync: In this mode one syncfs() is issued per batch (which, on Linux, guarantees the completion of write-out of dirty pages in the filesystem up to that point) and one single fsync() to synchronize or flush the controller/drive cache. This corresponds to -S 2 of fsmark. - syncfs-reverse-fsync: In this mode, one syncfs() is issued per batch, and all the open files in that batch are fsync()'ed in the reverse order of the queue. This corresponds to -S 4 of fsmark. - reverse-fsync: In this mode, no syncfs() is issued and all the files in the batch are fsync()'ed in the reverse order. This corresponds to -S 3 of fsmark.

* features/changelog: changelog translatorAvra Sengupta2013-07-223-11/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the initial version of the Changelog Translator. What is it ----------- Goal is to capture changes performed on a GlusterFS volume. The translator needs to be loaded on the server (bricks) and captures changes in a plain text file inside a configured directory path (controlled by "changelog-dir", should be somewhere in <export>/.glusterfs/changelog by default). Changes are classified into 3 types: - Data: : TYPE-I - Metadata : TYPE-II - Entry : TYPE-III Changelog file is rolled over after a certain time interval (defauls to 60 seconds) after which a changelog is started. The thing to be noted here is that for a time interval (time slice) multiple changes for an inode are recorded only once (ie. say for 100+ writes on an inode that happens within the time slice has only a single corresponding entry in the changelog file). That way we do not bloat up the changelog and also save lots of writes. Changelog Format ----------------- TYPE-I and TYPE-II changes have the gfid on the entity on which the operation happened. TYPE-III being a entry op requires the parent gfid and the basename. Changelog format has been kept to a minimal and it's upto the consumers to do the heavy loading of figuring out deletes, renames etc.. A single changelog file records all three types of changes, with each change starting with an identifier ("D": DATA, "M": METADATA and "E": ENTRY). Option is provided for the encoding type (See TUNABLES). Consumers ---------- The only consumer as of today would be geo-replication, although backup utilities, self-heal, bit-rot detection could be possible consumers in the future. CLI ---- By default, change-logging is disabled (the translator is present in the server graph but does nothing). When enabled (via cli) each brick starts to log the changes. There are a set of tunable that can be used to change the translators behaviour: - enable/disable changelog (disabled by default) gluster volume set <volume> changelog {on|off} - set the logging directory (<brick>/.glusterfs/changelogs is the default) gluster volume set <volume> changelog-dir /path/to/dir - select encoding type (binary (default) or ascii) gluster volume set <volume> encoding {binary|ascii} - change the rollover time for the logs (60 secs by default) gluster volume set <volume> rollover-time <secs> - when secs > 0, changelog file is not open()'d with O_SYNC flag - and fsync is trigerred periodically every <secs> seconds. gluster volume set <volume> fsync-interval <secs> features/changelog: changelog consumer library (libgfchangelog) A shared library is provided for the consumer of the changelogs for easy acess via APIs. Application can link against this library and request for changelog updates. Conversion of binary logs to human-readable ascii format is also taken care by the library which keeps a copy of the changelog in application provided working directory.

Some of the options have been backported to release-3.3 branch and hence should have their op-version reduced. Some other options had op-version incorrectly set as 1.

* posix: add a simple health-checkerNiels de Vos2013-07-031-0/+4

The current implementation requires the filesystem to detect the storage error, after which it will notify the parent xlators and exit the glusterfsd (brick) process to prevent further troubles. The interval the health-check runs can be configured per volume with the storage.health-check-interval option. The default interval is 30 seconds. It is not trivial to write an automated test-case with the current prove-framework. These are the manual steps that can be done to verify the functionality: - setup a Logical Volume (/dev/bz970960/xfs) and format is as XFS for brick usage - create a volume with the one brick # gluster volume create failing_xfs glufs1:/bricks/failing_xfs/data # gluster volume start failing_xfs - mount the volume and verify the functionality - make the storage fail (use device-mapper, or pull disks) # dmsetup table .. bz970960-xfs: 0 196608 linear 7:0 2048 # echo 0 196608 error > dmsetup-error-target # dmsetup load bz970960-xfs dmsetup-error-target # dmsetup resume bz970960-xfs # dmsetup table ... bz970960-xfs: 0 196608 error - notice the errors caught by syslog: Jun 24 11:31:49 vm130-32 kernel: XFS (dm-2): metadata I/O error: block 0x0 ("xfs_buf_iodone_callbacks") error 5 buf count 512 Jun 24 11:31:49 vm130-32 kernel: XFS (dm-2): I/O Error Detected.

* glusterd: Disable transport before cleaning up rpc objectKrishnan Parthasarathi2013-06-183-19/+99
| | | | | | | | | | | | | | | | | | | | | | | | | Problem: rpc_transport object, which is part of rpc_clnt, is destroyed prematurely. This is because, rpc_transport object is ref'd by socket layer and rpc layer. These ref's, until the synctask'izing of operations, were unref'd sequentially in the epoll thread. With more threads at play, the sequential unref guarantee is off. Fix: Shutting down the transport before proceeding with cleaning up of rpc_clnt object would serialize the unref's on the rpc_transport object and thus eliminating the race. Also, we don't store the address of brickinfo in brick's rpc notify function, to avoid the possibility of referring a freed brickinfo. Instead we use a string based id to 'reach' the corresponding brickinfo.

| | | | | | | | | | | | | | | | | | | | | | | | | glusterd could deadlock after a peer-detach command as follows, 1) glusterd_friend_cleanup function 'flushes' out messages in the rpc layer's queue, that haven't received a response. At this point, glusterd has already acquired the big lock. 2) The side-effect of flushing out the messages is that the corresponding call backs are called. Call backs themselves are executed after acquiring the big lock. This results in the big lock being acquired in a nested manner (in the same thread), which causes a deadlock. This can also happen during brick/NFS/SHD disconnect in volume-stop.
