* cluster/ec: Rebalance hangs during renameAshish Pandey2016-03-305-50/+177
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: During the rename of a particular file (ec is holding blocking inodelk on the parent directory), if the rename of another file under the same directory comes. EC does not release the lock and goes ahead and renames the "new" file with the "already held lock". That causes rebalance process to be blocked on a lock which has been acquired by rename. Solution: While rename fop comes, ec takes blocking inodelk on old and new parent of the file. Before releasing, every lock held by ec, it waits for some "time" to see if that lock can be reused by the next fop. If within this "time" some other request comes, it releases this lock based on condition "lock count > 1" To get this "lock count" for rename fop, we have implemented "pl_rename" in feature/lock. Also, on ec side, changed the condition to release the lock based on the type of fop and old and new parent directories.

* tier/dht : Attach tier fix layout to run in backgroundJoseph Fernandes2016-03-282-25/+247
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Spawn a thread for background fix-layout for tier process. 2. 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.)

When parent inode is linked in posix_build_ancestry, and before it reaches posix_acl_readdirp_cbkc, reate/lookup can come on a leaf-inode, as parent-inode-ctx not yet updated in posix_acl_readdirp_cbk, create/lookup can fail with EACCESS.

* dht: update attr information in refresh layout to avoidSakshi Bansal2016-03-231-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | stale timestamp Consider the scenario where an mkdir has just created the directory but has not healed it yet. 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.

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

* cluster/ec: Provide an option to enable/disable eager lockAshish Pandey2016-03-154-3/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: If a fop takes lock, and completes its operation, it waits for 1 second before releasing the lock. However, If ec find any lock contention within this time period, it release the lock immediately before time expires. As we take lock on first brick, for few operations, like read, it might happen that discovery of lock contention might take long time and can degrades the performance. Solution: Provide an option to enable/disable eager lock. If eager lock is disabled, lock will be released as soon as fop completes. gluster v set <VOLUME NAME> disperse.eager-lock on gluster v set <VOLUME NAME> disperse.eager-lock off Change-Id: I000985a787eba3c190fdcd5981dfbf04e64af166 BUG: 1314649 Signed-off-by: Ashish Pandey <aspandey@redhat.com> Reviewed-on: http://review.gluster.org/13605 Smoke: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> Tested-by: Pranith Kumar Karampuri <pkarampu@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org>

| | | | | | | | | | | | | | | | | | | | | | | | If there are large number of files to be migrated and by this time if the volume goes down, then the tierd has to be stopped. But on a huge query file list it keeps checking for each file before stopping. If the volume comes up before the old tierd dies then due to the presence of old tierd new one won't be created. After the old one completes the task, it dies and the status ends up as failed. This patch will check if the status is still running and then let it continue its work. Else it will stop running the tierd.

* cluster/ec: Do not ref dictionary in lookupPranith Kumar K2016-03-141-7/+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.

This patch will make the stale entry error to be skipped. Situation for pargfid to be stale: Consider a folder from a tar file. Once the tar file is untared the files in the tar-file will start to demote. when the demotion is under progress, if we tend to delete the actual folder, then the files under it which are undergoing demotion will do a lookup on the parent which was deleted and become stale entry. This stale entry fails the Lookup and this will fail the demotion of the other files(not from tar) that are supposed to be demoted.

| | | | | | | | | | | | | | | | | | | | | | There was a race between fdl_worker starting to run and setting this->private in fdl_init. This should never happen on a multiprocessor, since the new thread should start on a different core and creating it there should take many times longer than getting from pthread_create to the end of fdl_init on the original core. The only way it seems likely is if the new thread is started on the same core that's already in fdl_init, and the new thread preempts the old, which many would consider broken . . . but there are plenty of broken thread implementations and it's hardly surprising that glibc has one. Still, it's a race and it did show up in regression tests a few times, so it needs to be fixed.

* protocol client/server: Fix client-server handshakeAvra Sengupta2016-03-108-12/+155
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Currently on a successful connection between protocol server and client, the protocol client initiates a CHILD_UP event in the client stack. At this point in time, only the connection between server and client is established, and there is no guarantee that the server side stack is ready to serve requests. It works fine now, as most server side translators are not dependent on any other factors, before being able to serve requests today and hence they are up by the time the client stack translators receive the CHILD_UP (initiated by client handshake). The gap here is exposed when certain server side translators like NSR-Server for example, have a couple of protocol clients as their child(connecting them to other bricks), and they can't really serve requests till a quorum of their children are up. Hence these translators should defer sending CHILD_UP till they have enough children up, and the same needs to be propagated to the client stack translators. Fix: Maintain a child_up variable in both the protocol client and protocol server translators. The protocol server should update this value based on the CHILD_UP and CHILD_DOWN events it receives from the translators below it. On receiving such an event it should forward that event to the client. The protocol client on receiving such an event should forward it up the client stack, thereby letting the client translators correctly know that the server is up and ready to serve. The clients connecting later(long after a server has initialized and processed it's CHILD_UP events), will receive a child_up status as part of the handshake, and based on the status of the server's child_up, can either propagate a CHILD_UP event or defer it.
