* cluster/dht: Handle file migrations when brick downN Balachandran2018-04-181-5/+51
| | | | | | | | | | | | | | | | | | | The decision as to which node would migrate a file was based on the gfid of the file. Files were divided among the nodes for the replica/disperse set. However, if a brick was down when rebalance started, the nodeuuids would be saved as NULL and a set of files would not be migrated. Now, if the nodeuuid is NULL, the first non-null entry in the set is the node responsible for migrating the file.

* cluster/dht: Handle single dht child in dht_lookupN Balachandran2018-03-051-0/+10
| | | | | | | | | | | | | | | | | | | This patch limits itself to only handling the case where no file (data or linkto) exists on the subvol. Additional cases to be handled: 1. A linkto file was found on the only child subvol. This currently calls dht_lookup_everywhere which eventually deletes it. It can be deleted directly as it will not be pointing to a valid subvol. 2. Directory lookups - locking might be unnecessary in some cases. > Change-Id: I940ba34531f2aaee1d36fd9ca45ecfd46be662a4 > BUG: 1546620 > Signed-off-by: N Balachandran <nbalacha@redhat.com> Change-Id: I940ba34531f2aaee1d36fd9ca45ecfd46be662a4 BUG: 1548270 Signed-off-by: N Balachandran <nbalacha@redhat.com>

* cluster/dht: Use percentages for space checkN Balachandran2018-01-121-5/+20
| | | | | | | | | | | | | | | | | | | | | With heterogenous bricks now being supported in DHT we could run into issues where files are not migrated even though there is sufficient space in newly added bricks which just happen to be considerably smaller than older bricks. Using percentages instead of absolute available space for space checks can mitigate that to some extent. Marking bug-1247563.t as that used to depend on the easier code to prevent a file from migrating. This will be removed once we find a way to force a file migration failure. > Change-Id: I3452520511f304dbf5af86f0632f654a92fcb647 > BUG: 1529440 > Signed-off-by: N Balachandran <nbalacha@redhat.com> Change-Id: I3452520511f304dbf5af86f0632f654a92fcb647 BUG: 1530455 Signed-off-by: N Balachandran <nbalacha@redhat.com>
* cluster/dht: don't overfill the buffer in readdir(p)Raghavendra G2017-12-081-3/+18
| | | | | | | | | | | | | | | | | | | | | | | | Superflous dentries that cannot be fit in the buffer size provided by kernel are thrown away by fuse-bridge. This means, * the next readdir(p) seen by readdir-ahead would have an offset of a dentry returned in a previous readdir(p) response. When readdir-ahead detects non-monotonic offset it turns itself off which can result in poor readdir performance. * readdirp can be cpu-intensive on brick and there is no point to read all those dentries just to be thrown away by fuse-bridge. So, the best strategy would be to fill the buffer optimally - neither overfill nor underfill. > Change-Id: Idb3d85dd4c08fdc4526b2df801d49e69e439ba84 > BUG: 1492625 > Signed-off-by: Raghavendra G <rgowdapp@redhat.com> (cherry picked from commit e785faead91f74dce7c832848f2e8f3f43bd0be5) Change-Id: Idb3d85dd4c08fdc4526b2df801d49e69e439ba84 BUG: 1478411 Signed-off-by: Raghavendra G <rgowdapp@redhat.com>

* cluster/dht: fix crash when deleting directoriesZhang Huan2017-10-251-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | In DHT, after locks on all subvolumes are acquired, it would perform the following steps sequentially, 1. send remove dir on all other subvolumes except the hashed one in a loop; 2. wait for all pending rmdir to be done 3. remove dir on the hashed subvolume The problem is that in step 1 there is a check to skip hashed subvolume in the loop. If the last subvolume to check is actually the hashed one, and step 3 is quickly done before the last and hashed subvolume is checked, by accessing shared context data be destroyed in step 3, would cause a crash. Fix by saving shared data in a local variable to access later in the loop. > BUG: 1490642 > Signed-off-by: Zhang Huan <zhanghuan@open-fs.com> (cherry picked from commit 206120126d455417a81a48ae473d49be337e9463) Change-Id: I8db7cf7cb262d74efcb58eb00f02ea37df4be4e2 BUG: 1505221 Signed-off-by: N Balachandran <nbalacha@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Earlier, rebalance performed a fix-layout on a directory before healing its subdirectories. If there were a lot of subdirs, it could take a while before all subdirs were created on the newly added bricks. As dht_readdirp only lists dirs from their hashed subvol, those dirs which hashed to the newly added bricks but were not yet created on them were not listed. Now, the child dirs are listed and processed before the layout of the parent is fixed. This introduces a change in behaviour where files in subdirs are migrated before those in parent directories.

* cluster/dht: Check for open fd only on EBADFN Balachandran2017-08-094-160/+160
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DHT fd based fops used to check if the fd was open on the cached subvol before winding the call. However, this introduced a performance regression of about 30% for reads. This check was introduced to handle cases where files were migrated while IOs were happening. As this is not the common case, dht will now check if the fd is open on the cached subvol only if the call fails with EBADF. This will prevent a performance hit where a rebalance is not running. > BUG: 1476665 > Signed-off-by: N Balachandran <nbalacha@redhat.com> > Reviewed-on: https://review.gluster.org/17976 > Smoke: Gluster Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Amar Tumballi <amarts@redhat.com> > Reviewed-by: Susant Palai <spalai@redhat.com> > Reviewed-by: Raghavendra G <rgowdapp@redhat.com> (cherry picked from commit cdca1cb26a0aba390c6d8485c0d6d95e22ffc8bd) Change-Id: I2035a858d63c3fcd22bb634055bbb0ad01686808 BUG: 1479303 Signed-off-by: N Balachandran <nbalacha@redhat.com> Reviewed-on: https://review.gluster.org/17995 Smoke: Gluster Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To calculate available space on a subvolume we used to do the following in __dht_check_free_space. post_availspace = (dst_statfs.f_bavail * dst_statfs.f_frsize) - stbuf->ia_size Now to subtracting the file size from available space is tricky here. Sometime available space will be lesser than the file size and since all the participating members in calculation are unsigned int, the result is a large number (integer overflow). Solution: We do not need to subtract the file size from the space available, since fallocate would have reserved file size space already. > Change-Id: I4f724358c44b9911933742ff3ff8d55b3dfda1cb > BUG: 1475282 > Signed-off-by: Susant Palai <spalai@redhat.com> > Reviewed-on: https://review.gluster.org/17876 > Smoke: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Raghavendra G <rgowdapp@redhat.com> > Reviewed-by: N Balachandran <nbalacha@redhat.com> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Signed-off-by: Susant Palai <spalai@redhat.com> Change-Id: I4f724358c44b9911933742ff3ff8d55b3dfda1cb BUG: 1477152 Signed-off-by: Susant Palai <spalai@redhat.com> Reviewed-on: https://review.gluster.org/17942 Smoke: Gluster Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>

* cluster/rebalance: Fix hardlink migration failuresSusant Palai2017-07-132-15/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A brief about how hardlink migration works: - Different hardlinks (to the same file) may hash to different bricks, but their cached subvol will be same. Rebalance picks up the first hardlink, calculates it's hash(call it TARGET) and set the hashed subvolume as an xattr on the data file. - Now all the hardlinks those come after this will fetch that xattr and will create linkto files on TARGET (all linkto files for the hardlinks will be hardlink to each other on TARGET). - When number of hardlinks on source is equal to the number of hardlinks on TARGET, the data migration will happen. RACE:1 Since rebalance is multi-threaded, the first lookup (which decides where the TARGET subvol should be), can be called by two hardlink migration parallely and they may end up creating linkto files on two different TARGET subvols. Hence, hardlinks won't be migrated. Fix: Rely on the xattr response of lookup inside gf_defrag_handle_hardlink since it is executed under synclock. RACE:2 The linkto files on TARGET can be created by other clients also if they are doing lookup on the hardlinks. Consider a scenario where you have 100 hardlinks. When rebalance is migrating 99th hardlink, as a result of continuous lookups from other client, linkcount on TARGET is equal to source linkcount. Rebalance will migrate data on the 99th hardlink itself. On 100th hardlink migration, hardlink will have TARGET as cached subvolume. If it's hash is also the same, then a migration will be triggered from TARGET to TARGET leading to data loss. Fix: Make sure before the final data migration, source is not same as destination. RACE:3 Since a hardlink can be migrating to a non-hashed subvolume, a lookup from other client or even the rebalance it self, might delete the linkto file on TARGET leading to hardlinks never getting migrated. This will be addressed in a different patch in future.

* cluster/dht: rebalance gets file count periodicallyN Balachandran2017-06-234-30/+97
| | | | | | | | | | | | | | | | The rebalance used to get the file count in the beginning and not update it. This caused estimates to fail if the number changed during the rebalance. The rebalance now updates the file count periodically.

* dht/hardlink : Remove stale linkto file incase of failureJiffin Tony Thottan2017-06-223-1/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a similar issue fixed for rename in https://review.gluster.org/#/c/16016/ For hardlinks, if cached and hashed subvolumes are different, then it will first create linkto file in hashed using root permission, but actually hardlink creation fails with EACESS and stale linkto file is never removed.All the followup hardlink calls with file name will result ESTALE because linktofile creation fails with EEXIST and follow up lookup on linkto file returns gfid-mismatching(old linkto file) and finally fails with ESTALE Steps to produce : (From link/00.t test from posix-testsuite) Steps executed in script * create a file "abc" using root * change the ownership of file to a non root user * create hardlink "link" for "abc" using a non root user, it fails with EACESS * delete "abc" * create directory "abc" using root * again try to create hadrlink "link" for "abc" using non root user, fails with ESTALE Also tried to fix other bugs in dht_linkfile_create_cbk() and posix_lookup. Thanks Susant for the help in debugging the issue and suggestion for this patch.

* cluster/dht: Additional checks for rebalance estimatesN Balachandran2017-06-201-5/+15
| | | | | | | | | | | | | | | | | | | | | The rebalance estimates calculation was not handling calculations correctly when no files had been processed, i.e., when rate_lookedup was 0. Now, the estimated time is set to 0 in such scenarios as there is no way for rebalance to figure out how long the process will take to complete without knowing the rate at which the files are being processed.
