* afr: do not set arbiter as a readable subvol in inode contextRavishankar N2016-03-041-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: If afr_lookup_done() or afr_read_subvol_select_by_policy() chooses the arbiter brick to serve the stat() data, file size will be reported as zero from the mount, despite other data bricks being available. This can break programs like tar which use the stat info to decide how much to read. Fix: In the inode-context, mark arbiter as a non-readable subvol for both data and metadata. It it to be noted that by making this fix, we are *not* going to serve metadata FOPS anymore from the arbiter brick despite the brick storing the metadata. It makes sense to do this because the ever increasing over-loaded FOPs (getxattr returning stat data etc.) and compound FOPS in gluster will otherwise make it difficult to add checks in code to handle corner cases.

* cluster/afr: Don't delete gfid-req from lookup requestPranith Kumar K2016-03-022-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | Problem: Afr does dict_ref of the xattr_req that comes to it and deletes "gfid-req" key. Dht uses same dict to send lookup to other subvolumes. So in case of directories and more than 1 dht subvolumes, second subvolume till the last subvolume won't get a lookup request with "gfid-req". So gfid reset never happens on the directories in distributed replicate subvolume for 2nd till last subvolumes. Fix: Make a copy of lookup xattr request.

* afr: Add throttled background client-side healsRavishankar N2016-03-016-58/+200
| | | | | | | | | | | | | | | | | | | | | | | | | | | If a heal is needed after inode refresh (lookup, read_txn), launch it in the background instead of blocking the fop (that triggered refresh) until the heal happens. afr_replies_interpret() is modified such that the heal is launched only if atleast one sink brick is up. Max. no of heals that can happen in parallel is configurable via the 'background-self-heal-count' volume option. Any number greater than that is put in a wait queue whose length is configurable via 'heal-wait-queue-leng' volume option. If the wait queue is also full, further heals will be ignored. Default values: background-self-heal-count=8, heal-wait-queue-leng=128 Change-Id: I1d4a52814cdfd43d90591b6d2ad7b6219937ce70 BUG: 1297172 Signed-off-by: Ravishankar N <ravishankar@redhat.com> Reviewed-on: http://review.gluster.org/13207 Smoke: Gluster Build System <jenkins@build.gluster.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> 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>
* cluster/ec: Fix invalid config check for directoriesXavier Hernandez2016-02-292-1/+15
| | | | | | | | | | | | | | | | | | | | | | The trusted.ec.config xattr is not defined for directories. However sometimes it could be requested because the inode type of a directory can temporarily be IA_INVAL. Requesting such xattr using the xattrop fop when it doesn't exist, returns a config value full of 0's, which is invalid and caused some fops to fail. This patch filters out this case by ignoring config xattr == 0.

* cluster/tier: make promotion and demotion independantDan Lambright2016-02-282-126/+127
| | | | | | | | | | | | | | | | | | | | Currently a main loop in tiering spawns promotion and demotion threads, and does a join to wait for them to complete. When one of the two threads takes a long time, the main thread waits for it before exiting the join. It may wait so long the scheduled time for the other thread is skipped. In the case of demotion, it may be a long time before another attempt. This patch fixes that by making the promotion and demotion activities independant. A side effect of this change is the logic is significantly simplified.

* cli/ afr: op_ret for index heal launchRavishankar N2016-02-111-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: If index heal is launched when some of the bricks are down, glustershd of that node sends a -1 op_ret to glusterd which eventually propagates it to the CLI. Also, glusterd sometimes sends an err_str and sometimes not (depending on the failure happening in the brick-op phase or commit-op phase). So the message that gets displayed varies in each case: "Launching heal operation to perform index self heal on volume testvol has been unsuccessful" (OR) "Commit failed on <host>. Please check log file for details." Fix: 1. Modify afr_xl_op() to return -1 even if index healing of atleast one brick fails. 2. Ignore glusterd's error string in gf_cli_heal_volume_cbk and print a more meaningful message. The patch also fixes a bug in glusterfs_handle_translator_op() where if we encounter an error in notify of one xlator, we break out of the loop instead of sending the notify to other xlators.

| | | | | | | | | | | | | | | | | | | | A query to the database may take a long time if the database has many entries. The tier daemon also sends IPC calls to the bricks which can run slowly, espcially in RHEL6. While it is possible to track down each such instance, the snapshot feature should not be affected by database operations. It requires no migration be underway. Therefore it is okay to pause tiering at any time except when DHT is moving a file. This fix implements this strategy by monitoring when control passes to DHT to migrate a file using the GF_XATTR_FILE_MIGRATE_KEY trigger. If it is not, the pause operation is successful.

* cluster/dht : Ftruncate on migrating file fails with EINVALN Balachandran2015-12-229-80/+317
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | What: If dht_open is called on a migrating file after the inode_ctx is set, subsequent FOPs on that fd do not open the fd on the dst subvol. This is seen when the open-ftruncate-close sequence is repeatedly called on a migrating file. A second call to the sequence described above causes dht_truncate_cbk to call dht_truncate2 as the dht_inode_ctx was already set by the first call. As dht_rebalance_in_progress_check is not called, the fd is not opened on the dst subvol. On a distributed-replicate volume, this causes AFR to open the fd using afr_fix_open, but with the wrong flags, causing posix_ftruncate to fail with EINVAL. The fix: We require fd specific information to make a decision while handling migrating files. Set the fd_ctx to indicate the fd has been opened on the dst subvol and check if it has been set while processing Phase1/Phase2 checks in the FOP callback functions.

* cluster/tier: do not block in synctask created from pause tierDan Lambright2015-12-213-18/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | | We had run sleep() in the pause tier callback. Blocking within a synctask is dangerous. The sleep() call does not inform the synctask scheduler that a thread is no longer running. It therefore believes it is running. If a second synctask already exists, it may not be able to run. This occurs if the thread limit in the pool has been reached. Note the pool size only grows when a synctask is created, not when it is moved from wait state to run state, as is the case when an FOP completes. When the tier is paused during migration, synctasks already exist waiting for responses to FOPs to the server with high probability. The fix is to yield() in the RPC callback, which will place the synctask into the wait queue and free up a thread for the FOP callback. A timer wakes the callback after sufficient time has elapsed for the pause to occur.
