* geo-rep: Fix syncing of symlinkKotresh HR2018-06-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: If symlink is created on master pointing to current directory (e.g symlink -> ".") with non root uid or gid, geo-rep worker crashes with ENOTSUP. Cause: Geo-rep creates the symlink on slave and fixes the uid and gid using chown cmd. os.chown dereferences the symlink which is pointing to ".gfid" which is not supported. Note that geo-rep operates on aux-gfid-mount (e.g. "/mnt/.gfid/<gfid-of-symlink-file>"). Solution: The uid or gid change is acutally on symlink file. So use os.lchown, i.e, don't deference.

* geo-rep: Fix data sync issue during hardlink, renameKotresh HR2018-02-021-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: The data is not getting synced if master witnessed IO as below. 1. echo "test_data" > f1 2. ln f1 f2 3. mv f2 f3 4. unlink f1 On master, 'f3' exists with data "test_data" but on slave, only f3 exists with zero byte file without backend gfid link. Cause: On master, since 'f2' no longer exists, the hardlink is skipped during processing. Later, on trying to sync rename, since source ('f2') doesn't exist, dst ('f3') is created with same gfid. But in this use case, it succeeds but backend gfid would not have linked as 'f1' exists with the same gfid. So, rsync would fail with ENOENT as backend gfid is not linked with 'f3' and 'f1' is unlinked. Fix: On processing rename, if src doesn't exist on slave, don't blindly create dst with same gfid. The gfid needs to be checked, if it exists, hardlink needs to be created instead of mknod. Thanks Aravinda for helping in RCA :) > Change-Id: I5af4f99798ed1bcb297598a4bc796b701d1e0130 > Signed-off-by: Kotresh HR <khiremat@redhat.com> > BUG: 1512483 > Reporter: dimitri.ars@gmail.com (cherry picked from commit 6e2ce37341e5d600d8fd5648b39eec0dbdbe45ad) Change-Id: I5af4f99798ed1bcb297598a4bc796b701d1e0130 Signed-off-by: Kotresh HR <khiremat@redhat.com> BUG: 1510342

* geo-rep: Fix syncing of hardlink of symlinkKotresh HR2017-08-291-58/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: If there is a hardlink to a symlink on master and if the symlink file is deleted on master, geo-rep fails to sync the hardlink. Typical Usecase: It's easily hit with rsnapshot use case where it uses hardlinks. Example Reproducer: Setup geo-replication between master and slave volume and in master mount point, do the following. 1. mkdir /tmp/symlinkbug 2. ln -f -s /does/not/exist /tmp/symlinkbug/a_symlink 3. rsync -a /tmp/symlinkbug ./ 4. cp -al symlinkbug symlinkbug.0 5. ln -f -s /does/not/exist2 /tmp/symlinkbug/a_symlink 6. rsync -a /tmp/symlinkbug ./ 7. cp -al symlinkbug symlinkbug.1 Cause: If the source was not present while syncing hardlink, it was always packing the blob as regular file. Fix: If the source was not present while syncing hardlink, pack the blob based on the mode. > Change-Id: Iaa12d6f99de47b18e0650e7c4eb455f23f8390f2 > BUG: 1432046 > Signed-off-by: Kotresh HR <khiremat@redhat.com> > Reported-by: Christian Lohmaier <lohmaier+rhbz@gmail.com> > Reviewed-on: https://review.gluster.org/18011 > Smoke: Gluster Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Aravinda VK <avishwan@redhat.com> (cherry picked from commit e893962deaabab8e934813f8a0443a8f94e009f2) Change-Id: Iaa12d6f99de47b18e0650e7c4eb455f23f8390f2 BUG: 1486120 Signed-off-by: Kotresh HR <khiremat@redhat.com> Reviewed-on: https://review.gluster.org/18127 Smoke: Gluster Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com>
* geo-rep: Fix syncing of self healed hardlinksKotresh HR2017-07-311-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: In a distribute replicate volume, if the hardlinks are created when a subvolume is down, it gets healed from other subvolume when it comes up. If this subvolume becomes ACTIVE in geo-rep there are chances that those hardlinks won't be synced to slave. Cause: AFR can't detect hardlinks during self heal. It just create those files using mknod and the same is recorded in changelog. Geo-rep processes these mknod and ignores it as it finds gfid already on slave. Solution: Geo-rep should process the mknod as link if the gfid already exists on slave. > Change-Id: I2f721b462b38a74c60e1df261662db4b99b32057 > BUG: 1475308 > Signed-off-by: Kotresh HR <khiremat@redhat.com> > Reviewed-on: https://review.gluster.org/17880 > Smoke: Gluster Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Aravinda VK <avishwan@redhat.com> (cherry picked from commit d685e4238fafba8f58bf01174c79cb5ca35203e5) Change-Id: I2f721b462b38a74c60e1df261662db4b99b32057 Signed-off-by: Kotresh HR <khiremat@redhat.com> BUG: 1476208 Reviewed-on: https://review.gluster.org/17905 Smoke: Gluster Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Aravinda VK <avishwan@redhat.com>

* geo-rep: Optionally allow access to mountsKotresh HR2017-03-191-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | In order to improve debuggability, it is important to have access to geo-rep master and slave mounts. With the default behaviour, geo-rep lazy unmounts the mounts after changing the current working directory into the mount point. It also cleans up the mount points. So only geo-rep worker has the access and it becomes impossible to take the client profile info and do any other client statck analysis. Hence the following new config is being introduced to allow access to mounts. gluster vol geo-rep <mastervol> <slavehost>::<slavevol> \ config access_mount true The default value of 'access_mount' is false.

Geo-rep gets EACCES when it tries to create a new entry using gfid-access with different UID/GID. With this patch, Entry creation with different UID/GID is split into two operations.

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.

* geo-rep: Avoid cold tier bricks during ENTRY operationSaravanakumar Arumugam2015-10-261-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* geo-rep: Disable xattrs and acls support with tar_sshKotresh HR2015-05-281-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 VK2015-05-051-21/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
