* afr: add errno to afr_inode_refresh_done()Ravishankar N2017-06-191-7/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of https://review.gluster.org/17413 and https://review.gluster.org/17436 Problem: When parellel `rm -rf`s were being done from cifs clients, opendir might fail on some replicas with ENOENT. DHT ignores partial opendir failures in dht_fd_cbk() and winds readdirs on those replicas. Afr inode refresh (as a part of readdirp read_txn) sees in its fd context that the state of the fds is *not* AFR_FD_OPENED and bails out to afr_inode_refresh_done() without doing a refresh. When this happens, the errno is set as EIO due to lack of readable subvols, logging split-brain messages in the logs. Fix: Introduce an errno argument to afr_inode_refresh_do() to bail out with the right error value when inode refresh is not performed.

* afr: send the correct iatt values in fsync cbkRavishankar N2017-05-171-25/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: afr unwinds the fsync fop with an iatt buffer from one of its children on whom fsync was successful. But that child might not be a valid read subvolume for that inode because of pending heals or because it happens to be the arbiter brick etc. Thus we end up sending the wrong iatt to mdcache which will in turn serve it to the application on a subsequent stat call as reported in the BZ. Fix: Pick a child on whom the fsync was successful *and* that is readable as indicated in the inode context. > Reviewed-on: https://review.gluster.org/17227 > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > Smoke: Gluster Build System <jenkins@build.gluster.org> (cherry picked from commit 1a8fa910ccba7aa941f673302c1ddbd7bd818e39) Change-Id: Ie8647289219cebe02dde4727e19a729b3353ebcf BUG: 1449941 RCA'ed-by: Miklós Fokin <miklos.fokin@appeartv.com> Signed-off-by: Ravishankar N <ravishankar@redhat.com> Reviewed-on: https://review.gluster.org/17248 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: jiffin tony Thottan <jthottan@redhat.com>
* afr: propagate correct errno for fop failures in arbiterRavishankar N2017-05-174-15/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: If quorum is not met in fop cbk, arbiter sends an ENOTCONN error to the upper xlators. In a VM workload with sharding enabled, this was leading to the VM pausing when replace-brick was performed as described in the BZ. Fix: Move the fop cbk arbitration logic to afr_handle_quorum() because in normal replica volumes, that is the function that has the quorum and errno checks in the fop cbk path before doing a post-op. Thanks to Pranith for suggesting this approach. > Reviewed-on: https://review.gluster.org/17235 > Smoke: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> (cherry picked from commit 93c850dd2a513fab75408df9634ad3c970a0e859) Change-Id: Ie6315db30c5e36326b71b90a01da824109e86796 BUG: 1450937 Signed-off-by: Ravishankar N <ravishankar@redhat.com> Reviewed-on: https://review.gluster.org/17296 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> Reviewed-by: jiffin tony Thottan <jthottan@redhat.com>

* afr: don't do a post-op on a brick if op failedRavishankar N2017-04-291-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: In afr-v2, self-blaming xattrs are not there by design. But if the FOP failed on a brick due to an error other than ENOTCONN (or even due to ENOTCONN, but we regained connection before postop was wound), we wind the post-op also on the failed brick, leading to setting self-blaming xattrs on that brick. This can lead to undesired results like healing of files in split-brain etc. Fix: If a fop failed on a brick on which pre-op was successful, do not perform post-op on it. This also produces the desired effect of not resetting the dirty xattr on the brick, which is how it should be because if the fop failed on a brick, there is no reason to clear the dirty bit which actually serves as an indication of the failure. > Reviewed-on: https://review.gluster.org/16976 > Smoke: Gluster Build System <jenkins@build.gluster.org> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> Change-Id: I5f1caf4d1b39f36cf8093ccef940118638caa9c4 BUG: 1443319 Signed-off-by: Ravishankar N <ravishankar@redhat.com> Reviewed-on: https://review.gluster.org/17082 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com>

But failed_subvols[i] is true even if the brick was down *before* the transaction started. Hence say if 1 brick is down in a replica-3, every writev that comes will trigger an inode refresh because of this resetting, as seen from the no. of FSTATs in the profile info in the BZ. Fix: Reset event gen only if the brick was previously a valid read child and the FOP failed on it the first time. Also `s/afr_inode_read_subvol_reset/afr_inode_event_gen_reset` because the function only resets event gen and not the data/metadata readable. > Reviewed-on: http://review.gluster.org/16309 > Smoke: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> > Tested-by: Pranith Kumar Karampuri <pkarampu@redhat.com> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> (cherry picked from commit 522640be476a3f97dac932f7046f0643ec0ec2f2) Change-Id: I603ae646cbde96995c35db77916e2ed80b602a91 BUG: 1412888 Signed-off-by: Ravishankar N <ravishankar@redhat.com> Reviewed-on: http://review.gluster.org/16386 NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Krutika Dhananjay <kdhananj@redhat.com> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.org>

Consider following case, a user is trying to rename a file which he is not permitted. So the rename fails with EACESS and when rename tries to cleanup the linkto file, it fails. The above issue happens when rename/00.t test executed on nfs-ganesha clients : Steps executed in script * create a file "abc" using root * rename the file "abc" to "xyz" using a non root user, it fails with EACESS * delete "abc" * create directory "abc" using root * again try ot rename "abc" to "xyz" using non root user, test hungs here which slowly leds to OOM kill of ganesha process RCA put forwarded by Du for OOM kill of ganesha Note that when we hit this bug, we've a scenario of a dentry being present as: * a linkto file on one subvol * a directory on rest of subvols When a lookup happens on the dentry in such a scenario, the control flow goes into an infinite loop of: dht_lookup_everywhere dht_lookup_everywhere_cbk dht_lookup_unlink_cbk dht_lookup_everywhere_done dht_lookup_directory (as local->dir_count > 0) dht_lookup_dir_cbk (sets to local->need_selfheal = 1 as the entry is a linkto file on one of the subvol) dht_lookup_everywhere (as need_selfheal = 1). This infinite loop can cause increased consumption of memory due to: 1) dht_lookup_directory assigns a new layout to local->layout unconditionally 2) Most of the functions in this loop do a stack_wind of various fops.

* cluster/afr: Fix missing name indices due to EEXIST errorKrutika Dhananjay2016-12-291-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of: http://review.gluster.org/16286 PROBLEM: Consider a volume with granular-entry-heal and sharding enabled. When a replica is down and a shard is created as part of a write, the name index is correctly created under indices/entry-changes/<dot-shard-gfid>. Now when a read on the same region triggers another MKNOD, the fop fails on the online bricks with EEXIST. By virtue of this being a symmetric error, the failed_subvols[] array is reset to all zeroes. Because of this, before post-op, the GF_XATTROP_ENTRY_OUT_KEY will be set, causing the name index, which was created in the previous MKNOD operation, to be wrongly deleted in THIS MKNOD operation. FIX: The ideal fix would have been for a transaction to delete the name index ONLY if it knows it is the one that created the index in the first place. This would involve gathering information as to whether THIS xattrop created the index from individual bricks, aggregating their responses and based on the various posisble combinations of responses, decide whether to delete the index or not. This is rather complex. Simpler fix would be for post-op to examine local->op_ret in the event of no failed_subvols to figure out whether to delete the name index or not. This can occasionally lead to creation of stale name indices but they won't be affecting the IO path or mess with pending changelogs in any way and self-heal in its crawl of "entry-changes" directory would take care to delete such indices.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of: http://review.gluster.org/16075 Incorrect initialisation of local->optimistic_change_log was leading to skipped pre-op and post-op even when a brick didn't participate in the txn because it was down. The result - missing granular name index resulting in some entries never getting healed. FIX: Initialise local->optimistic_change_log just before pre-op. Also fixed granular entry heal to create the granular name index in pre-op as opposed to post-op. This is to prevent loss of granular information when during an entry txn, the good (src) brick goes offline before the post-op is done. This would cause self-heal to do conservative merge (since dirty xattr is the only information available), which when granular-entry-heal is enabled, expects granular indices, the lack of which can lead to loss of data in the worst case.

Shard xlator was sending a fxattrop to update the file size immediately after a writev. Arbiter was incorrectly over-riding the LLONGMAX-1 start offset (for metadata domain locks) for this fxattrop, causing the inodelk to be taken on the data domain. And since the preceeding writev hadn't released the lock (afr does a 'lazy' unlock if write succeeds on all bricks), this degraded to a blocking lock causing extra lock/unlock calls and delays.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: For healing of uid/gid we check if local->stbuf.ia_ctime is lesser than stbuf->ia_ctime (received from brick).

So if we receive response from the newly added brick first and update the local->stbuf, then local->prebuf will remain empty since the newly added brick will have the latest ctime among all servers. And this can result in healing wrong uid/gids to the rest of servers. Hence, we should update local->stbuf from servers with a layout which will ignore merging stbufs from newly added bricks. > Reviewed-on: http://review.gluster.org/15126 > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > Smoke: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Raghavendra G <rgowdapp@redhat.com> (cherry picked from commit 36af81ac7cb2d459f9bfc0c436f0038a68f85235) Change-Id: If4b64f75a0ea669abdbe9f5a3d1d18ff19374c2f BUG: 1375096 Signed-off-by: Susant Palai <spalai@redhat.com> Reviewed-on: http://review.gluster.org/15464 NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>
* afr: Ignore gluster internal (virtual) xattrs in metadata heal checkRavishankar N2016-09-291-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | Backport of http://review.gluster.org/#/c/15548/ Problem: In arbiter configuration, posix-xlator in the arbiter brick always sets the GF_CONTENT_KEY in the response dict with a value 0. If the file size on the data bricks is more than quick-read's max-file-size (64kb default), those bricks don't set the key. Because of this difference in the no. of dict elements, afr triggers metadata heal in lookup code path, in turn leading to extra lookups+inodelks. Fix: Changed afr dict comparison logic to ignore all virtual xattrs and the on-disk ones that we should not be healing.

* dht: "replica.split-brain-status" attribute value is not correctMohit Agrawal2016-09-262-12/+210
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: In a distributed-replicate volume attribute "replica.split-brain-status" value does not display split-brain condition though directory is in split-brain. If directory is in split brain on mutiple replica-pairs it does not show full list of replica pairs. Solution: Update the dht_aggregate code to aggregate the xattr value in this specific condition. Fix: 1) function getChoices returns the choices from split-brain status string. 2) function add_opt adding the choices to local buffer to store in dictionary 3) For the key "replica.split-brain-status" function dht_aggregate call dht_aggregate_split_brain_xattr to prepare the list. Test: To verify the patch followed below steps 1) Create a distributed replica volume and create mount point 2) Stop heal daemon 3) Touch file and directories on mount point mkdir test{1..5};touch tmp{1..5} 4) Down brick process on one of the replica set pkill -9 glusterfsd 5) Change permission of dir on mount point chmod 755 test{1..5} 6) Restart brick process on node with force option 7) kill brick process on other node in same replica set 8) Change permission of dir again on mount point chmod 766 test{1..5} 9) Reexecute same step from 4-9 on other replica set also 10) After check heal status on server it will show dir's are in split brain on all replica sets 11) After check the replica.split-brain-status attr on mount point it will show wrong status of split brain. 12) After apply the patch the attribute shows correct value. > Change-Id: Icdfd72005a4aa82337c342762775a3d1761bbe4a > Signed-off-by: Mohit Agrawal <moagrawa@redhat.com> > Reviewed-on: http://review.gluster.org/15201 > Smoke: Gluster Build System <jenkins@build.gluster.org> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Raghavendra G <rgowdapp@redhat.com> > (cherry picked from commit c4e9ec653c946002ab6d4c71ee8e6df056438a04) Change-Id: I85a5ae60189066d9e80799f00f1352c2f33ef4f8 Backport of commit c4e9ec653c946002ab6d4c71ee8e6df056438a04 BUG: 1375098 Signed-off-by: Mohit Agrawal <moagrawa@redhat.com> Reviewed-on: http://review.gluster.org/15467 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>
* cluster/dht: heal root permission post add-brickSusant Palai2016-09-132-5/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Post add-brick event the new brick will have permission of 755 by default. If the root directory permission was other than 755, that does not get healed to the new brick leading to permission errors/inconsistencies. For choosing source of attr heal we can trust the subvols which have layouts with latest ctime(as part of missing directory heal, we heal the proper attr). In case none of the subvols have layout, return ESTALE to retrigger a fresh lookup. Note: This patch heals the permission of the root directories only. Since, permission healing of directory is not straight forward and required intrusive fix, those are not addressed here. > Reviewed-on: http://review.gluster.org/15195 > Smoke: Gluster Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> >Reviewed-by: Raghavendra G <rgowdapp@redhat.com> (cherry picked from commit 801cd07a4c6ec65ff930b2ae6bb5e405ccd03334) Change-Id: If894e3895d070d46b62d2452e52c1eaafcf56c29 BUG: 1374573 Signed-off-by: Susant Palai <spalai@redhat.com> Reviewed-on: http://review.gluster.org/15465 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>
