* geo-rep: Handling Rsync/Tar errors efficientlyAravinda VK2016-02-262-87/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | Geo-rep processes Changelogs in Batch, if one file in batch fails with rsync error that Changelog file is reprocessed multiple times. After MAX_RETRY, it logs all the GFIDs from that batch as Skipped. This patch addresses following issues, 1. When Rsync/Tar fails do not parse Changelog again for retry 2. When Rsync/Tar fails do not replay Entry operations, only retry rsync/tar for those GFIDs 3. Log Error in Rsync/Tar only in the last Retry 4. Do not log Skipped GFIDs since Rsync/Tar errors are logged for only failed files. 5. Changed Entry failures as Error instead of Warning BUG: 1287723 Change-Id: Ie134ce2572693056ab9b9008cd8aa5b5d87f7975 Signed-off-by: Aravinda VK <avishwan@redhat.com> Reviewed-on: http://review.gluster.org/12856 Reviewed-by: Kotresh HR <khiremat@redhat.com> Reviewed-by: Saravanakumar Arumugam <sarumuga@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Smoke: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Venky Shankar <vshankar@redhat.com>
* geo-rep: Handle ERANGE error during listxattrAravinda VK2016-02-261-7/+21
| | | | | | | | | | | | | | | | | | | | | | | | llistxattr in Geo-rep is two syscall instead of one SIZE = llistxattr(PATH, &BUF, 0); BUF = create_buf(SIZE); _ = llistxattr(PATH, &BUF, SIZE); So if any new xattrs added just after first call by any other worker, second syscall will fail with ERANGE error. Now Geo-rep sends BUF with large size(256*100) and gets value with only one syscall. Raises OSError if fails with ERANGE error even after sending large BUF.

* geo-rep: Handle hardlink in Tiering based volumeSaravanakumar Arumugam2016-02-261-10/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Hardlinks are synced as Sticky bit files to Slave in a Tiering based volume. In a Tiering based volume, cold tier is hashed subvolume and geo-rep captures all namespace operations in cold tier. While syncing a file and its corresponding hardlink, it is recorded as MKNOD in cold tier(for both) and We end up creating two different files in Slave. Solution: If MKNOD with Sticky bit set is present, record it as LINK. This way it will create a HARDLINK if source file exists (on slave), else it will create a new file. This way, Slave can create Hardlink file itself (instead of creating a new file) in case of hardlink.

* geo-rep: use cold tier bricks for namespace operationsSaravanakumar Arumugam2015-12-034-17/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: symlinks are not getting synced to slave in a Tiering based volume. Solution: Now, symlinks are created directly in cold tier bricks( in the backend). Earlier, cold tier was avoided for namespace operations and only hot tier was used while processing changelogs. Now, cold tier is HASH subvolume in a Tiering volume. So, carry out namespace operation only in cold tier subvolume and avoid hot tier subvolume to avoid any races. Earlier, XSYNC was used(and changeloghistory avoided) during initial sync in order to avoid race while processing historychangelog in Hot tier. This is no longer required as there is no race from Hot tier. Also, avoid both live and history changelog ENTRY operations from Hot tier to avoid any race with cold tier.

But with shard translator being enabled on slave, doing entry creation with MKNOD and SETATTR is not allowed, SETATTR fails as it accesses inode structure which is not linked.

* geo-rep: Avoid cold tier bricks during ENTRY operationSaravanakumar Arumugam2015-10-264-5/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a series of patch which aims to fix geo-replication in a Tiering Volume. Problem: Consider, a file is placed in volume initially and then hot tier is attached. During any operation on the file, due to lookup a linkto file is created in hot tier. Now, any namespace operation carried out on the file is recorded in both cold and hot tier. There is a room for races when both changelogs are replayed. Solution: So, We are going to replay (namespace related)operations only in the hot tier. Why? a. If the file is directly placed in Hot tier , all fops will be recorded in HOT tier. b. If the file is already present in Cold tier, and if any fop is carried out, it creates linkto file in Hot tier. Now, operations like UNLINK, RENAME are captured in Hot tier(by means of linkto file). This way, we can get both tier's operation in HOT tier itself. Now, once the file is demoted to COLD tier, any namespace operation carried out on the cold tier can be avoided as we directly RECORD the same in HOT tier. How? 1. Check whether the brick is cold tier and skip ENTRY operation. 2. Also, if it is cold tier brick, use Xsync(which is used during initial run). This will help in getting all cold tier bricks changes using File System crawl and helps in avoiding races with hot tier brick(which can happen if historychangelog used in cold tier brick).

Hence register_time would be less then stime for which history obviously fails. But it will be successful for the next restart as new register_time > stime. Fix is to pass current time as the end time to history call instead of the register_time. Also improvised the logging for ACTIVE/PASSIVE switching.

Memory for the new string is obtained with malloc(3), and can be freed with free(3). so when using strdup, user has to take care of freeing the memory allocated by strdup library function. 2. leak in main() function: str2argv() function calls calloc and allocates memory pointed to argv, after return from str2argv() memory pointed to argv has to be cleaned in main(). This patch is to fix 2 memory leaks mentioned above.

* geo-rep: Disable xattrs and acls support with tar_sshKotresh HR2015-05-282-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Geo-rep can't sync xattrs and acls with tar over ssh for following reasons. Issue 1: xattrs doesn't sync with tar over ssh. Reason: untar doesn't respect '--overwrite' option when used along with '--xattrs'. So it sends unlink if the file exists on destination and re-creates afresh. But all entry operations are banned in aux-gfid-mount as it may lead to gfid-mismatch. Hence fails with EPERM. This happens only when some xattr is set on a file in master volume. Issue2: acls on directories does not sync with tar over ssh. Reason: tar tries to opendir ".gfid/<gfid1>" and is not supported by gfid-access-translator as readirp can't be handled on virtual inodes and hence fails with ENOTSUP where as it syncs for files. Since the issue is with tar commmand it self and nothing could be done from gluster side, disabling xattr and acls support with tar over ssh option. Geo-rep can sync xattrs and acls with 'rsync' as the sync engine.

* geo-rep: Minimize rm -rf race in Geo-repAravinda VK2015-05-053-26/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While doing RMDIR worker gets ENOTEMPTY because same directory will have files from other bricks which are not deleted since that worker is slow processing. So geo-rep does recursive_delete. Recursive delete was done using shutil.rmtree. once started, it will not check disk_gfid in between. So it ends up deleting the new files created by other workers. Also if other worker creates files after one worker gets list of files to be deleted, then first worker will again get ENOTEMPTY again. To fix these races, retry is added when it gets ENOTEMPTY/ESTALE/ENODATA. And disk_gfid check added for original path for which recursive_delete is called. This disk gfid check executed before every Unlink/Rmdir. If disk gfid is not matching with GFID from Changelog, that means other worker deleted the directory. Even if the subdir/file present, it belongs to different parent. Exit without performing further deletes. Retry on ENOENT during create is ignored, since if CREATE/MKNOD/MKDIR failed with ENOENT will not succeed unless parent directory is created again. Rsync errors handling was handling unlinked_gfids_list only for one Changelog, but when processed in batch it fails to detect unlinked_gfids and retries again. Finally skips the entire Changelogs in that batch. Fixed this issue by moving self.unlinked_gfids reset logic before batch start and after batch end. Most of the Geo-rep races with rm -rf is eliminated with this patch, but in some cases stale directories left in some bricks and in mount point we get ENOTEMPTY.(DHT issue, Error will be logged in Slave log) BUG: 1211037 Change-Id: I8716b88e4c741545f526095bf789f7c1e28008cb Signed-off-by: Aravinda VK <avishwan@redhat.com> Reviewed-on: http://review.gluster.org/10204 Reviewed-by: Kotresh HR <khiremat@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Tested-by: NetBSD Build System Reviewed-by: Vijay Bellur <vbellur@redhat.com>
