* cluster/afr: Check for required number of entrylksRavishankar N2016-05-251-5/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of: http://review.gluster.org/14358 Problem: Parallel rmdir operations on the same directory results in ENOTCONN messages eventhough there was no network disconnect. In blocking entry lock during rmdir, AFR takes 2 set of locks on all its children-One (parentdir,name of dir to be deleted), the other (full lock on the dir being deleted). 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().

* cluster/afr : Do post-op in case of symmetric errorsAnuradha Talur2016-05-231-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of: http://review.gluster.org/#/c/14310/ In afr_changelog_post_op_now(), if there was any error, meaning op_ret < 0, post-op was not being done even when the errors were symmetric and there were no "failed subvols". 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: 1335836 Signed-off-by: Anuradha Talur <atalur@redhat.com> Reviewed-on: http://review.gluster.org/14332 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: Pranith Kumar Karampuri <pkarampu@redhat.com>

* quota: setting 'read-only' option in xdata to instruct DHT to not healSakshi Bansal2016-04-261-2/+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.

* dht: add "nuke" functionality for efficient server-side deletionJeff Darcy2016-04-261-0/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a backport of the following two patches (of which the second is a trivial adjustment to a timeout for a test added by the first). http://review.gluster.org/13878 http://review.gluster.org/13935 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.

* 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. >BUG: 1322850 >Change-Id: Ia563c5f096b5922009ff0ec1c42d969d55d827a3 >Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> >Reviewed-on: http://review.gluster.org/13873 >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: Ashish Pandey <aspandey@redhat.com> >Reviewed-by: Anuradha Talur <atalur@redhat.com> >Reviewed-by: Krutika Dhananjay <kdhananj@redhat.com> >(cherry picked from commit b6a0780d86e7c6afe7ae0d9a87e6fe5c62b4d792) Change-Id: If7eee18843b48bbeff4c1355c102aa572b2c155a BUG: 1294675 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> Reviewed-on: http://review.gluster.org/14039 Reviewed-by: Krutika Dhananjay <kdhananj@redhat.com> 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>

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch addresses two races while renaming directories: 1) While renaming src to dst, if a lookup selfheal is triggered it can recreate src on those subvols where rename was successful. This leads to multiple directories (src and dst) having same gfid. To avoid this we must take locks on all subvols with src. 2) While renaming if the dst exists and a lookup selfheal is triggered it will find anomalies in the dst layout and try to heal the stale layout. To avoid this we must take lock on any one subvol with dst.

* cluster/ec: Do not ref dictionary in lookupPranith Kumar K2016-04-091-7/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: 1) dict_for_each loops over the elements without any locks, so the members of the dictionary can be ref/unrefed while dict_for_each is executed by another thread leading to crashes. Basically with distributed ec + disctributed replicate as cold, hot tiers. tier sends a lookup which fails on ec. (By this time dict already contains ec xattrs) After this lookup_everywhere code path is hit in tier which triggers lookup on each of distribute's hash lookup but fails which leads to the cold, hot dht's lookup_everywhere in two parallel epoll threads where in ec when it tries to set trusted.ec.version/dirty/size as keys in the dictionary, the older values against the same key get erased. While this erasing is going on if the thread that is doing lookup on afr's subvolume accesses these keys either in dict_copy_with_ref or client xlator trying to serialize, that can either lead to crash or hang based on if the spin/mutex lock is called on invalid memory. 2) EC deletes GF_CONTENT_KEY from the dictionary, this may lead to extra reads in case of lookup-everwhere for tiered volumes. Fix: Do dict_copy_with_ref() for the lookup-dictionary. This is avoiding the problem and is not actually fixing the 1st problem. 2nd problem will be fixed. >Change-Id: I5427aa14c48cb7572977d4de9a28c5ffff2b4b95 >BUG: 1315560 >Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> >Reviewed-on: http://review.gluster.org/13680 >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: Xavier Hernandez <xhernandez@datalab.es> >(cherry picked from commit 64cba025b13aad7fb3020a04930cfa22fbfcb859) Change-Id: I2828a0d9e730bc4b0ea6cee037365131767ae43e BUG: 1322520 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> Reviewed-on: http://review.gluster.org/13859 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: Krutika Dhananjay <kdhananj@redhat.com> Smoke: Gluster Build System <jenkins@build.gluster.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At current state rebalance aborts basically on any failure like fix-layout of a directory, readdirp, opendir etc. Unless it is not a remove-brick process we can ignore these failures. Major impact: Any failure in the gf_defrag_process_dir means there are files left unmigrated in the directory. Fix-layout(setxattr) failure will impact it's child subtree i.e. the child subtree will not be rebalanced. Settle-hash (commit-hash)failure will trigger lookup_everywhere for immediate children until the next commit-hash. Note: Remove-brick opertaion is still sensitive to any kind of failure.

* tier/dht : Attach tier fix layout to run in backgroundJoseph Fernandes2016-04-012-24/+247

Once the fix-layout is completed a marker xttr is set on the root of volume to mark the completion of the background fixlayout, so that even if the tier process is spawned again, fixlayout will not be issued, if it was completed last time. 3. Please note that promotion of legacy files will happen eventually as the ctr lookup heal in the fixlayout slowly heals the ctr db for legacy files OR the ctr lookup heal happend due to a name lookup. 4. When a detach tier is successful in evacuation data from hot tier, we remove the marker xattr is removed. So that next attach tier runs the background tier fixlayout. what is remaining ? 1. Instead of clearing the marker xattr of tiering fix layout at the end of detach start clear it during detach commit. But the issue is detach commit is a glusterd operation and the volume is not mounted in glusterd. The reason we want to do it in detach commit is that if the admin wants to attach the same tier again, then a background fixlayout will be triggered, which would not be needed. 2. Clearing the CTR DB of the cold bricks when there is a detach commit, as it will be having entries which will be stale when the volume is used, with ctr off (ctr is switched off only when we have detach commit.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Directory size is meaningless. Every filesystem has its own unpredictable way of increasing or decreasing it, based on internal data structures and even transient conditions. Some filesystems (e.g. ext4) never decrease it at all. Others (e.g. btrfs) don't even report it. Very few programs look at it, and those that do are broken. Unfortunately, one such program is GNU tar, which will complain when it sees different values because at different times we got the value from different DHT subvolumes. To avoid such problems, just report a constant value.

A parallel lookup on this entry will find anomalies and trigger a selfheal which will sample the ctime of the directory after the mkdir phase. Meanwhile the mkdir has completed setting the layout and updated the ctime. The selfheal then sees the layout to be healed and returns with the ctime it got after the mkdir phase which has now become stale. However if the lookup happens to unwind before the mkdir then the inode associated with lookup will get linked in the inode table which has the stale ctime. To avoid this selfheal must do an iatt_merge in refresh layout to get the latest timestamp irrespective of whether it needs to heal the layout or not.
