This patch improves the locking mechanism which can improve the performance as well reduce memory consumption Problem-2) For every lookup and for all inodes in readdirp we were initiating a new txn, this can result in more txn pending in synctask queue and lead to huge memory consumption. inspect file/dir should start a txn only if there is some delta Problem-3) When there are multiple write operations on same inode and all the synctask threads are busy. As we are checking for updation_status flag in background, all txn will be move to synctask queue. This can increase the mem usage. Only one txn for inode in a queue will be sufficient, so check and set updation falg before moving txn to background > Change-Id: Ic42ce00f0a50ce51c7128ba68a1b6a0699a1cd14 > BUG: 1207735 > Signed-off-by: vmallika <vmallika@redhat.com> Change-Id: I52a05b99b19b97c79b69671120f53e05481f99cd BUG: 1229282 Signed-off-by: vmallika <vmallika@redhat.com> Reviewed-on: http://review.gluster.org/11527 Tested-by: NetBSD Build System <jenkins@build.gluster.org> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Raghavendra G <rgowdapp@redhat.com> Tested-by: Raghavendra G <rgowdapp@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | inode quota is a new feature implemented in glusterfs-3.7 if quota is enabled in the older version and is upgraded to a new version, we can hit setxattr spike during self-heal of inode quotas. So, when a quota is enabled, turn off inode-quotas with a xlator option. With this patch, we still account for inode quotas but only when a write operation is performed for a particular file. User will be able to query inode quotas once the Inode-quota xlator option is enabled.

* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-044-77/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glusterfs relies on Linux uuid implementation, which API is incompatible with most other systems's uuid. As a result, libglusterfs has to embed contrib/uuid, which is the Linux implementation, on non Linux systems. This implementation is incompatible with systtem's built in, but the symbols have the same names. Usually this is not a problem because when we link with -lglusterfs, libc's symbols are trumped. However there is a problem when a program not linked with -lglusterfs will dlopen() glusterfs component. In such a case, libc's uuid implementation is already loaded in the calling program, and it will be used instead of libglusterfs's implementation, causing crashes. A possible workaround is to use pre-load libglusterfs in the calling program (using LD_PRELOAD on NetBSD for instance), but such a mechanism is not portable, nor is it flexible. A much better approach is to rename libglusterfs's uuid_* functions to gf_uuid_* to avoid any possible conflict. This is what this change attempts.

| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the only way to retrieve the number of files/objects in a directory or volume is to do a crawl of the entire directory/volume. This is expensive and is not scalable. The new mechanism proposes to store count of objects/files as part of an extended attribute of a directory. Each directory's extended attribute value will indicate the number of files/objects present in a tree with the directory being considered as the root of the tree. Currently file usage is accounted in marker by doing multiple FOPs like setting and getting xattrs. Doing this with STACK WIND and UNWIND can be harder to debug as involves multiple callbacks. In this code we are replacing current mechanism with syncop approach as syncop code is much simpler to follow and help us implement inode quota in an organized way.

* feature/geo-rep: Keep marker.tstamp's mtime unchangeable during snapshot.Kotresh H R2014-08-041-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Geo-replicatoin does a full xsync crawl after snapshot restoration of slave and master. It does not do history crawl. Analysis: Marker creates 'marker.tstamp' file when geo-rep is started for the first time. The virtual extended attribute 'trusted.glusterfs.volume-mark' is maintained and whenever it is queried on gluster mount point, marker fills it on the fly and returns the combination of uuid, ctime of marker.tstamp and others. So ctime of marker.tstamp, in other sense 'volume-mark' marks the geo-rep start time when the session is freshly created. From the above, after the first filesystem crawl(xsync) is done during first geo-rep start, stime should always be less than 'volume-mark'. So whenever stime is less than volume-mark, it does full filesystem crawl (xsync). Root Cause: When snapshot is restored, marker.tstamp file is freshly created losing the timestamps, it was originally created with. Solution: 1. Change is made to depend on mtime instead of ctime. 2. mtime and atime of marker.tstamp is restored back when snapshot is created and restored.

Problem: After disabling and then enabling quota back, the xattrs may contain stale data leading to impaired accounting and thus improper enforcement. Solution: Clean up all the quota related xattrs after quota disable. Marker xlator implements a virtual xattr to cleanup quota and pgfid xattrs.

Zerofill writes zeroes to a file in the specified range. This fop will be useful when a whole file needs to be initialized with zero (could be useful for zero filled VM disk image provisioning or during scrubbing of VM disk images). Client/application can issue this FOP for zeroing out. Gluster server will zero out required range of bytes ie server offloaded zeroing. In the absence of this fop, client/application has to repetitively issue write (zero) fop to the server, which is very inefficient method because of the overheads involved in RPC calls and acknowledgements. WRITESAME is a SCSI T10 command that takes a block of data as input and writes the same data to other blocks and this write is handled completely within the storage and hence is known as offload . Linux ,now has support for SCSI WRITESAME command which is exposed to the user in the form of BLKZEROOUT ioctl. BD Xlator can exploit BLKZEROOUT ioctl to implement this fop. Thus zeroing out operations can be completely offloaded to the storage device , making it highly efficient. The fop takes two arguments offset and size. It zeroes out 'size' number of bytes in an opened file starting from 'offset' position. This patch adds zerofill support to the following areas: - libglusterfs - io-stats - performance/md-cache,open-behind - quota - cluster/afr,dht,stripe - rpc/xdr - protocol/client,server - io-threads - marker - storage/posix - libgfapi Client applications can exloit this fop by using glfs_zerofill introduced in libgfapi.FUSE support to this fop has not been added as there is no system call for this fop. Changes from previous version 3: * Removed redundant memory failure log messages Changes from previous version 2: * Rebased and fixed build error Changes from previous version 1: * Rebased for latest master TODO : * Add zerofill support to trace xlator * Expose zerofill capability as part of gluster volume info Here is a performance comparison of server offloaded zeofill vs zeroing out using repeated writes.

Due to this cascading setups were broken. This patch introduces "geo-replication.ignore-pid-check" option as a "override" for the client-pid check for gsyncd's client-pid. When this options is enabled, marker start "marking" even if the updates are from the special client. Geo-Replication on the detection of itself being an intermediate master, enables this option.

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.

* gsync: Display additional information in status commandsarvotham s pai2013-04-042-4/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | Added code to display extra information when status command is executed. Information shown now are 1 Number of files synced 2 crawl time 3 total sync time 4 bytes synced bytes synced is taken from rsync output . --stats option of rsync gives extra infor mation about the sync.In stats output there is a field called Total transferred file size which states the ammount of bytes synced . This information is parsed from stdout output using regular expressions.Bytes synced information can be used to calculate throughput.

Logging is done in the error handling routine, so any further changes that require unlinking of the timestamp file due to some error condition(s) are logged.

* geo-rep: retire old style ssh setupCsaba Henk2013-03-141-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | Users are still using geo-rep with the old, deprecated, insecure, unsupported ssh setup. Not their fault -- the implementation of the new method had the following charasteristics: - old method is possible, but with default settings it's not working - it can be made operational by fiddling with "remote-gsyncd" tunable - with default setting, an unhelpful, actually misleading error message is produced - the UI gave no hint to the changes in the ssh setup http://review.gluster.org/4392 tried to fix these; what it accomplished was unrestricted support to the bad practice (by making the default old setup operational). From this on: - we disable the old method by reserving the "remote-gsyncd" tunable - if the old method is attempted, give a hint what to do Change-Id: Icade94725d8d8d2d4c89cab992d4226351637b86 BUG: 895656 Signed-off-by: Csaba Henk <csaba@redhat.com> Reviewed-on: http://review.gluster.org/4602 Reviewed-by: Venky Shankar <vshankar@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>
