* ec: Invalidations in disperse volume should not update the statPoornima G2017-01-172-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of http://review.gluster.org/16329 Issue: In disperse volume, the file is present across bricks, hence the stat from one brick doesn't carry the valid size of the file. Therefore the upcall from one brick updating the md-cache results in wrong size being updated. Fix: If the notification is cache invalidation then, indicate md-cache that the attributes is invalid. >Reviewed-on: http://review.gluster.org/16329 >Smoke: Gluster Build System <jenkins@build.gluster.org> >NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> >Reviewed-by: Xavier Hernandez <xhernandez@datalab.es> >CentOS-regression: Gluster Build System <jenkins@build.gluster.org> >Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> (cherry picked from commit 95d07a3d2d68805d93d36a447436e27c48777939) BUG: 1410688 Change-Id: Id89d2283478e70b62b435a8891fffc86d2be8cb2 Signed-off-by: Poornima G <pgurusid@redhat.com> Reviewed-on: http://review.gluster.org/16341 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>
* cluster/afr: Remove backward compatibility for locks with v1Pranith Kumar K2017-01-172-69/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we have cascading locks with same lk-owner there is a possibility for a deadlock to happen. One example is as follows: self-heal takes a lock in data-domain for big name with 256 chars of "aaaa...a" and starts heal in a 3-way replication when brick-0 is offline and healing from brick-1 to brick-2 is in progress. So this lock is active on brick-1 and brick-2. Now brick-0 comes online and an operation wants to take full lock and the lock is granted at brick-0 and it is waiting for lock on brick-1. As part of entry healing it takes full locks on all the available bricks and then proceeds with healing the entry. Now this lock will start waiting on brick-0 because some other operation already has a granted lock on it. This leads to a deadlock. Operation is waiting for unlock on "aaaa..." by heal where as heal is waiting for the operation to unlock on brick-0. Initially I thought this is happening because healing is trying to take a lock on all the available bricks instead of just the bricks that are participating in heal. But later realized that same kind of deadlock can happen if a brick goes down after the heal starts but comes back before it completes. So the essential problem is the cascading locks with same lk-owner which were added for backward compatibility with afr-v1 which can be safely removed now that versions with afr-v1 are already EOL. This patch removes the compatibility with v1 which requires cascading locks with same lk-owner. In the next version we can make locking-scheme option a dummy and switch completely to v2. >BUG: 1401404 >Change-Id: Ic9afab8260f5ff4dff5329eb0429811bcb879079 >Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> >Reviewed-on: http://review.gluster.org/16024 >Smoke: Gluster Build System <jenkins@build.gluster.org> >Reviewed-by: Ravishankar N <ravishankar@redhat.com> >NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> >CentOS-regression: Gluster Build System <jenkins@build.gluster.org> BUG: 1413062 Change-Id: I4f5d485d9e0646ad3dc384e5ec36682b0933c9d3 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> Reviewed-on: http://review.gluster.org/16413 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>

* afr: Avoid resetting event_gen when brick is always downRavishankar N2017-01-133-19/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: __afr_set_in_flight_sb_status(), which resets event_gen to zero, is called if failed_subvols[i] is non-zero for any brick. 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. > Signed-off-by: Ravishankar N <ravishankar@redhat.com> > 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: 1412886 Reviewed-on: http://review.gluster.org/16385 Tested-by: Ravishankar N <ravishankar@redhat.com> Smoke: Gluster Build System <jenkins@build.gluster.org> 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | private If reconfigure is executed parallely (or concurrently with dht_init), there are races that can corrupt memory. One such race is modification of regexes stored in conf (conf->rsync_regex_valid and conf->extra_regex_valid) through dht_init_regex. With change [1], reconfigure codepath can get executed parallely (with itself or with dht_init) and this fix is needed. Also, a reconfigure can race with any thread doing dht_layout_search, resulting in dht_layout_search accessing regex freed up by reconfigure (like in bz 1399134).

* cluster/afr: Fix missing name indices due to EEXIST errorKrutika Dhananjay2016-12-281-0/+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.

Here is a brief on the same. DHT: - All the subvolumes reported once, and atleast one child came up, then GF_EVENT_CHILD_UP is issued - connect GF_EVENT_CHILD_UP is issued - disconnect GF_EVENT_CHILD_MODIFIED is issued - All the subvolumes disconnected, GF_EVENT_CHILD_DOWN is issued AFR: - First subvolume came up, then GF_EVENT_CHILD_UP is issued - Subsequent subvolumes coming up, results in GF_EVENT_CHILD_MODIFIED - Any of the subvolumes go down, then GF_EVENT_SOME_CHILD_DOWN is issued - Last up subvolume goes down, then GF_EVENT_CHILD_DOWN is issued Until the patch [1] introduced GF_EVENT_SOME_CHILD_UP, GF_EVENT_CHILD_MODIFIED was issued by afr/dht when any of the subvolumes go up or down. Now with md-cache changes, there is a necessity to differentiate between child up and down. Hence, introducing GF_EVENT_SOME_DESCENDENT_DOWN/UP and getting rid of GF_EVENT_CHILD_MODIFIED.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Currently, I/O on a split-brained file fails even when the favorite-child-policy is set until the self-heal is complete. Fix: If a valid 'source' is found using the set favorite-child-policy,inspect and reset the afr pending xattrs on the 'sinks' (inside appropriate locks),refresh the inode and then proceed with the read or write transaction. The resetting itself happens in the self-heal code and hence can also happen in the client side background-heal or by the shd's index-heal in addition to the txn code path explained above. When it happens in via heal, we also add checks in undo-pending to not reset the sink xattrs again. > Reviewed-on: http://review.gluster.org/15673 > Tested-by: Pranith Kumar Karampuri <pkarampu@redhat.com> > 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> Change-Id: Ic8c1317720cb26bd114b6fe6af4e58c73b864626 BUG: 1403121 Signed-off-by: Ravishankar N <ravishankar@redhat.com> Reported-by: Simon Turcotte-Langevin <simon.turcotte-langevin@ubisoft.com> Reviewed-on: http://review.gluster.org/16088 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: Pranith Kumar Karampuri <pkarampu@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Generally linkto file is created using root user. 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. This results in growing of call stack (note that call-stack is destroyed only after lookup response is received by fuse - which never happens in this case) Thanks Du for root causing the oom kill and Sushant for suggesting the fix Upstream reference : >Change-Id: I1e16bc14aa685542afbd21188426ecb61fd2689d >BUG: 1397052 >Signed-off-by: Jiffin Tony Thottan <jthottan@redhat.com> >Reviewed-on: http://review.gluster.org/15894 >NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> >CentOS-regression: Gluster 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 57d59f4be205ae0c7888758366dc0049bdcfe449) Change-Id: I1e16bc14aa685542afbd21188426ecb61fd2689d BUG: 1401023 Signed-off-by: Jiffin Tony Thottan <jthottan@redhat.com> Reviewed-on: http://review.gluster.org/16014 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: Kaleb KEITHLEY <kkeithle@redhat.com>

* md-cache, afr: Reduce the window of stale readPoornima G2016-12-012-2/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Consider a replica setup, where one mount writes data to a file and the other mount reads the file. In afr, read operations are not transaction based, a brick(read subvolume) is chosen as a part of lookup or other operations, read is always wound only to the read subvolume, even if there was write from a different client that failed on this brick. This stale read continues until there is a lookup or any write operation from the mount point. Currently, this is not a major issue, as a lookup is issued before every read and it will switch the read subvolume to a correct one. But with the plan of increasing md-cache timeout to 600s, the stale read problem will be more pronounced, i.e. stale read can continue for 600s(or more if cascaded with readdirp), as there will be no lookups. Solution: Afr doesn't have any built-in solution for stale read(without affecting the performance). The solution that came up, was to use upcall. When a file on any brick is marked bad for the first time, upcall sends a notification to all the clients that had recently accessed the file. The solution has 2 parts: - Identifying when a file is marked bad, on any of the bricks, for the first time - Client side actions on recieving the notifications Identifying when a file is marked bad on any of the bricks for the first time: ----------------------------------------------------------------------------- The idea is to track xattrop in upcall. xattrop currently comes with 2 afr xattrs - afr dirty bit and afr pending xattrs. Dirty xattr is set to 1 before every write, and is unset if write succeeds. In certain scenarios, dirty xattr can be 0 and still the file could be bad copy. Hence do not track dirty xattr. Pending xattr is set on the good copy, indicating the other bricks that have bad copy. It is still not as simple as, notifying when any of the pending xattrs change. It could lead to flood of notifcations, in case the other brick is completely down or consistantly failing. Hence it is important to notify only once, the first time a good copy is marked bad. Client side actions on recieving pending xattr change, notification: -------------------------------------------------------------------- md-cache will invalidate the cache of that file, so that further lookup is passed down to afr and hence update the read subvolume. Invalidating only in md-cache is not enough, consider the folling oder of opertaions: - pending xattr invalidation - invalidate md-cache - readdirp on the bad read subvolume - fill md-cache - lookup (served from md-cache) - read - wound to the old read subvol. Hence, along with invalidating md-cache, it is very important to reset the read subvolume for that file, in afr. Design Credit: Anuradha Talur, Ravishankar N 1. xattrop doesn't carry info saying post op/pre op. 2. Pre xattrop will have 0 value for all pending xattrs, the cbk of pre xattrop carries the on-disk xattr value. Non zero indicated healing is required. 3. Post xattrop will have non zero value for any of the pending xattrs, if the fop failed on any of the bricks. >Reviewed-on: http://review.gluster.org/15398 >Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> >Tested-by: Pranith Kumar Karampuri <pkarampu@redhat.com> >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> >Signed-off-by: Poornima G <pgurusid@redhat.com> Change-Id: I469cbc111714c433984fe1c922be2ef113c25804 BUG: 1399450 Signed-off-by: Poornima G <pgurusid@redhat.com> Reviewed-on: http://review.gluster.org/15958 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>

* cluster/afr: Fix deadlock due to compound fopsKrutika Dhananjay2016-11-271-14/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of: http://review.gluster.org/15929 When an afr data transaction is eligible for using eager-lock, this information is represented in local->transaction.eager_lock_on. However, if non-blocking inodelk attempt (which is a full lock) fails, AFR falls back to blocking locks which are range locks. At this point, local->transaction.eager_lock[] per brick is reset but local->transaction.eager_lock_on is still true. When AFR decides to compound post-op and unlock, it is after confirming that the transaction did not use eager lock (well, except for a small bug where local->transaction.locks_acquired[] is not considered). But within afr_post_op_unlock_do(), afr again incorrectly sets the lock range to full-lock based on local->transaction.eager_lock_on value. This is a bug and can lead to deadlock since the locks acquired were range locks and a full unlock is being sent leading to unlock failure and thereby every other lock request (be it from SHD or other clients or glfsheal) getting blocked forever and the user perceives a hang. FIX: Unconditionally rely on the range locks in inodelk object for unlocking when using compounded post-op + unlock. Big thanks to Pranith for helping with the debugging.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Sharding exposed a bug in arbiter config. where `dd` throughput was extremely slow. 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. Fix: Modify flock.l_len and flock.l_start to take full locks only for data transactions. > Reviewed-on: http://review.gluster.org/15641 > 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> (cherry picked from commit 3a97486d7f9d0db51abcb13dcd3bc9db935e3a60) Change-Id: I906895da2f2d16813607e6c906cb4defb21d7c3b BUG: 1385224 Signed-off-by: Ravishankar N <ravishankar@redhat.com> Reported-by: Max Raba <max.raba@comsysto.com> Reviewed-on: http://review.gluster.org/15648 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> Smoke: Gluster Build System <jenkins@build.gluster.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Also removed is_virtual_xattr() function. The original callers to this function (upcall) don't seem to need it anymore. > Reviewed-on: http://review.gluster.org/15548 > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Smoke: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> (cherry picked from commit 5afc6aba906a21aee19c2f1baaa7d9eb762ae0ac) Change-Id: I05730bdd39d8fb0b9a49a5fc9c0bb01f0d3bb308 BUG: 1379528 Signed-off-by: Ravishankar N <ravishankar@redhat.com> Reviewed-on: http://review.gluster.org/15577 NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | Added the following events for the eventing framework: "EVENT_AFR_QUORUM_MET", --> Sent when quorum is met. "EVENT_AFR_QUORUM_FAIL" -->Sent when quorum is lost. "EVENT_AFR_SUBVOL_UP" -->Sent when afr witnesses the first up subvolume. "EVENT_AFR_SUBVOLS_DOWN"-->Sent when all children of an afr subvol are down. "EVENT_AFR_SPLIT_BRAIN" -->Sent when self-heal detects split-brain in heal path (not read/write path).

* dht, md-cache, upcall: Add invalidation of IATT when the layout changesPoornima G2016-08-301-1/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: dht_layout is built as a part of lookup only. The layout can be modified by rebalance process. Since every IO fop is preceded by a lookup, there are very less issues of stale layout. But with enhancements of aggressive caching of stats in md-cache, the lookup will reduce and expose the stale layout issue often. Solution: Since stale layout is already an issue on dht, there is already a plan to fix this at the dht layer, but this fix is not currently planned for any release. Until this fix comes out, we can have a workaround where, the upcall will send a notification to md-cache when a layout xattr is changed. As a part of layout change notification the existing cache is invalidated and the next lookup will fetch the latest layout. This is not a foolproof solution as the window between the layout change and the next lookup(after invalidation of stat), where there will be stale layout. But until the final fix comes in, this reduces the stale layout window.
