* cluster/afr: Unwind with xdata in inode-write fopsPranith Kumar K2016-06-134-10/+12

* cluster/ec: Pass xdata to dht in case of errorAshish Pandey2016-06-131-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | Problem: In case of mkdir failure, dht expects error information so that it can act accordingly. Aftre adding bricks and re balance, layout gets changed. Fop "mkdir" with old layout returns EIO. EC gets this error in xdata but does not pass it back to dht. In this case dht will not be able to take corrective action. Solution: Return xdata back to dht master - http://review.gluster.org/#/c/14679/ Change-Id: I24def8038e6880607689b7b046dc6428f564c6ab BUG: 1344594 Signed-off-by: Ashish Pandey <aspandey@redhat.com> Reviewed-on: http://review.gluster.org/14690 Smoke: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Xavier Hernandez <xhernandez@datalab.es> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Niels de Vos <ndevos@redhat.com>
* cluster/ec: Fix invalid __fd_unref() callXavier Hernandez2016-06-131-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | __fd_unref() doesn't do any cleanup, so it cannot be called to release fd references, specially if it's the last reference. The code has been changed to avoid a call to this function. In the previous version we always tried to keep the newest fd in the ec_lock_t structure. However this is not necessary. We'll always keep one reference to an open file on the same inode. It's irrelevant if the reference is new or old. The function __fd_unref() has also been removed from fd.h to avoid being used in the future since it's useless as it's defined now.

* afr: Consider ENOSPC and EDQUOT as symmetric errorsRavishankar N2016-06-131-5/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of http://review.gluster.org/#/c/14604/ Problem: Since commit 8eaa3506ead4f11b81b146a9e56575c79f3aad7b, in replica 3, if a brick is down and a create fails on the other 2 brick with EDQUOT, we consider it an unsymmetric error and hence do not do post-op. So the dirty xattr remains set on the parent dir, leading to conservative merges during heal when all bricks are up. i.e. a file deleted on the source might re-appear after heal. Fix: Consider ENOSPC and EDQUOT as symmetric errors since there is no possibility of partial inode or entry modification operations possible when quota is enabled. IOW, if quota reports EDQUOT, the no. of bytes written (or not written) will be the same on all bricks of the replica. Likewise, the entry operation (create, mkdir...) will either succeed or not succeed on all bricks.

Fix: Refresh inode for inode-write fops for the ctx to be set if it is not already done at the time of named fresh-lookup or if the file is in split-brain where we need to perform one more refresh before failing the fop to check if the file is still in split-brain or not. >BUG: 1336612 >Change-Id: I5c50b62c8de06129b8516039f7c252e5008c47a5 >Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> >Reviewed-on: http://review.gluster.org/14368 >Smoke: Gluster Build System <jenkins@build.gluster.com> >NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> >Reviewed-by: Ravishankar N <ravishankar@redhat.com> >CentOS-regression: Gluster Build System <jenkins@build.gluster.com> BUG: 1337822 Change-Id: I0f904ebaa78b99cbb11546e08c9fc1562e9a3eef Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> Reviewed-on: http://review.gluster.org/14449 Smoke: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Krutika Dhananjay <kdhananj@redhat.com> Reviewed-by: Anuradha Talur <atalur@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Niels de Vos <ndevos@redhat.com>

We proceed to pre-op stage even if only a single lock (but not all the needed locks) was obtained, only to fail it with ENOTCONN because afr_locked_nodes_get() returns zero nodes in afr_changelog_pre_op(). Fix: After we get replies for all blocking lock requests, if we don't have the minimum number of locks to carry out the FOP, unlock and fail the FOP. The op_errno will be that of the last failed reply we got, i.e. whatever is set in afr_lock_cbk().

Fix: When the errors are symmetric, perform post-op. How was the bug found : In a 1 X 3 volume with shard and write behind on when writes were done into a file with one brick down, the trusted.afr.dirty xattr's value for .shard directory would keep increasing as post op was not done but pre-op was. This incorrectly showed .shard to be in split-brain. RCA: When WB is on, due to multiple writes being sent on offset lying in the same shard, chances are that same shard file will be created more than once with the second one failing with op_ret < 0 and op_errno = EEXIST. As op_ret was negative, afr wouldn't do post-op, leading to no decrement of trusted.afr.dirty xattr. Thus showing .shard directory to be in split-brain. >Change-Id: I711bdeaa1397244e6a7790e96f0c84501798fc59 >BUG: 1335652 >Signed-off-by: Anuradha Talur <atalur@redhat.com> Change-Id: I711bdeaa1397244e6a7790e96f0c84501798fc59 BUG: 1335829 Signed-off-by: Anuradha Talur <atalur@redhat.com> Reviewed-on: http://review.gluster.org/14331 NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Ravishankar N <ravishankar@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Niels de Vos <ndevos@redhat.com>

| | | | | | | | | | | | | | | | | | | | | This patch reverts changes introduced by commit 6e635284a4411b816d4d860a28262c9e6dc4bd6a in the release-3.8 branch. The commit itself was inherited from http://review.gluster.org/#/c/12738/ in master when the branch was created. Reverting it for the same reason it was reverted in 3.7 branch as well: It breaks the rolling upgrade scenario and these changes will be required only when server side AFR materializes, possibly for gluster 4.0.

This would lead to situations where failure of clearing the xattr would cause the premature death of migration threads. Now we clear the xattr only after the data movement threads join, ensuring that all migration is done.

* cluster/afr: Don't let NFS cache stat after writesPranith Kumar K2016-05-144-6/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Afr does post-ops after write but the stat buffer it unwinds is at the time of write, so if nfs client caches this, it will see different ctime when it does stat on it after post-op is done. From NFS client's perspective it thinks the file is changed. Tar which depends on this to be correct keeps giving 'file changed as we read it' warning. If Afr instead has to choose to unwind after post-op, eager-lock, delayed-post-op will have to be disabled which will lead to bad performance for all write usecases. Fix: Don't let client cache stat after write. >Change-Id: Ic6062acc6e5cdd97a9c83c56bd529ec83cee8a23 >BUG: 1302948 >Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> >Signed-off-by: Anuradha Talur <atalur@redhat.com> >Reviewed-on: http://review.gluster.org/13785 >Smoke: Gluster Build System <jenkins@build.gluster.com> >NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> >CentOS-regression: Gluster Build System <jenkins@build.gluster.com> >Reviewed-by: Niels de Vos <ndevos@redhat.com> BUG: 1335285 Change-Id: Ibef4fc80496d12acd15db57713af2e3a1c9109a7 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> Reviewed-on: http://review.gluster.org/14300 Smoke: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Ravishankar N <ravishankar@redhat.com> Reviewed-by: Niels de Vos <ndevos@redhat.com>

This may not be suitable for scenarios, where the file in the query are too big to move in the first cycle, as a result file in the other query files always get missed. We need to shuffle so that other query files also get a chance. Fix: Remember the previous first query file and shift it by one index, before the migration starts.

These will be addressed in subsequent patches. This patch addresses only mkdir codepath. This change breaks stripe tests, as on some striped subvols dht layout xattrs are not set for some reason. This results in failure of mkdir. Since striped volumes are always created with dht, some tests associated with stripe also fail. So, I am making following tests changes (since stripe is out of maintainance): * modify ./tests/basic/rpc-coverage.t to not to use striped volumes * mark all (2) tests in tests/bugs/stripe/ as bad tests Change-Id: Idd1ae879f24a48303dc743c1bb4d91f89a629e25 BUG: 1323040 Signed-off-by: Raghavendra G <rgowdapp@redhat.com> Reviewed-on: http://review.gluster.org/13885 Smoke: Gluster Build System <jenkins@build.gluster.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: N Balachandran <nbalacha@redhat.com>
* cluster/afr: Fix spurious entries in heal infoPranith Kumar K2016-04-204-16/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Locking schemes in afr-v1 were locking the directory/file completely during self-heal. Newer schemes of locking don't require Full directory, file locking. But afr-v2 still has compatibility code to work-well with older clients, where in entry-self-heal it takes a lock on a special 256 character name which can't be created on the fs. Similarly for data self-heal there used to be a lock on (LLONG_MAX-2, 1). Old locking scheme requires heal info to take sh-domain locks before examining heal-state. If it doesn't take sh-domain locks, then there is a possibility of heal-info hanging till self-heal completes because of compatibility locks. But the problem with heal-info taking sh-domain locks is that if two heal-info or shd, heal-info try to inspect heal state in parallel using trylocks on sh-domain, there is a possibility that both of them assuming a heal is in progress. This was leading to spurious entries being shown in heal-info. Fix: As long as there is afr-v1 way of locking, we can't fix this problem with simple solutions. If we know that the cluster is running newer versions of locking schemes, in those cases we can give accurate information in heal-info. So introduce a new option called 'locking-scheme' which if it is 'granular' will give correct information in heal-info. Not only that, Extra network hops for taking compatibility locks, sh-domain locks in heal info will not be necessary anymore. Thus it improves performance.

* quota: setting 'read-only' option in xdata to instruct DHT to not healSakshi Bansal2016-04-191-2/+10
| | | | | | | | | | | | | | | | | | | | | | When quota is enabled the quota enforcer tries to get the size of the source directory by sending nameless lookup to quotad. But if the rename is successful even on one subvol or the source layout has anomalies then this nameless lookup in quotad tries to heal the directory which requires a lock on as many subvols as it can. But src is already locked as part of rename. For rename to proceed in brick it needs to complete a cluster-wide lookup. But cluster-wide lookup in quotad is blocked on locks held by rename, hence a deadlock. To avoid this quota sends an option in xdata which instructs DHT not to heal.

* cluster/afr: Fix partial heals in 3-way replicationPranith Kumar K2016-04-155-15/+138
| | | | | | | | | | | | | | | | | | | | | | Problem: When there are 2 sources and one sink and if two self-heal daemons try to acquire locks at the same time, there is a chance that it gets a lock on one source and sink leading partial to heal. This will need one more heal from the remaining source to sink for the complete self-heal. This is not optimal. Fix: Upgrade non-blocking locks to blocking lock on all the subvolumes, if the number of locks acquired is majority and there were eagains.

* cluster/afr: Fix witness counting code in src/sink detectionPranith Kumar K2016-04-111-7/+19
| | | | | | | | | | | | | | | | | | | | | | | Problem: In afr-v1 pre-op, xattrop increments self xattr first then it increments the value on rest. In post-op, xattr value is decreased first on rest and at last it gets decremented on self. So for a possible operation to be witnessed i.e. a fop is seen by the brick it is important to have at least 1 pending op because without completing pre-op fop won't come. The other possibility is when fop completes but at the time of post-op after decrementing pending counts on others just before decrementing its own pending count, the brick dies.

* arbiter: write performance improvementRavishankar N2016-04-112-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: The throughput for a 'dd' workload was much less for arbiter configuration when compared to normal replica-3 volume. There were 2 issues: i)arbiter_writev was using the request dict as response dict while unwinding, leading to incorect GLUSTERFS_WRITE_IS_APPEND and GLUSTERFS_OPEN_FD_COUNT values (=4), leading to immediate post-ops because is_afr_delayed_changelog_post_op_needed() failed due to afr_are_multiple_fds_opened() check. ii) The arbiter code in afr was setting local->transaction.{start and len} =0 to take full file locks. What this meant was even for simultaenous but non-overlapping writevs, afr_transaction_eager_lock_init() was not happening because afr_locals_overlap() always stays true. Consequently is_afr_delayed_changelog_post_op_needed() failed due to local->delayed_post_op not being set. Fix: i) Send appropriate response dict values in arbiter_writev. ii) Modify flock params instead of local->transaction.{start and len} to take full file locks in the transaction. Also changed _fill_writev_xdata() in posix to fill rsp_xdata for whatever key is requested for.

* dht: add "nuke" functionality for efficient server-side deletionJeff Darcy2016-04-071-0/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This turns a special xattr into an rmdir with flags set. When that hits the posix translator on the server side, that causes the file/directory to be moved into the special "landfill" directory. From there, the posix janitor thread will take care of deleting it entirely on the server side - traversing it recursively if necessary. A couple of secondary issues were fixed to make this effective. * FUSE now ensures that setxattr values are NUL terminated. * The janitor thread now gets woken up immediately when something is placed in 'landfill' instead of only when file descriptors need to be closed. * The default landfill-emptying interval was reduced to 10s. To use the feature, issue a setxattr something like this: setfattr -n glusterfs.dht.nuke -v "" /mnt/glusterfs/vol/some_dir The value doesn't actually matter; the mere receipt of a request with this key is sufficient. Some day it might be useful to allow setting a required value as a sort of password, so that only those who know it can access the underlying special functionality.
