* glusterd: Removed 'proactive' failing of volume opKrishnan Parthasarathi2013-04-301-53/+3
| | | | | | | | | | | | | | | | | | | Volume operations were failed 'proactively', on the first disconnect of a peer that was participating in the transaction. The reason behind having this kludgey code in the first place was to 'abort' an ongoing volume operation as soon as we perceive the first disconnect. But the rpc call backs themselves are capable of injecting appropriate state machine events, which would set things in motion for an eventual abort of the transaction.

* tests: Modified test to use remove-brick instead of 'start' variantKrishnan Parthasarathi2013-04-301-2/+1
| | | | | | | | | | | | | | | | | | | remove-brick start doesn't remove the brick from the volume immediately. It would wait until migration of data to other bricks are complete. Even when there is no data to be migrated, one can expect a finite delay from the time of remove-brick start command's exit and removal of brick(s). This may cause subsequent checks on brick count to fail in a non-deterministic manner. Also, renamed the test file name to reflect bug-id corresponding to community release.

* extras: include Fedora changes in init.d/glusterdNiels de Vos2013-04-291-23/+73
| | | | | | | | | | | | | | | | | | | | | The changes in the .spec file from Fedora have largely been merged into the glusterfs.spec.in. It seems that some dependencies have been missed, most importantly some additions to the init-script that are called while (un)installing or updating RPMs. These changes come from the downstream Fedora package that carries its own glusterd.init script. In future, Fedora/EPEL should be able to drop that file and use the Gluster project version.

* glusterd: Introduce volume op-versionsKaushal M2013-04-2611-419/+600
| | | | | | | | | | | | | | | | | | | | | | | Each volume is now associated with two op-versions, * op_version - the op-version of the highest op-versioned feature enabled * client_op_version - the op-version of the highest op-versioned feature enabled which affects the clients only. These two op-versions are generated dynamically and kept updated during runtime. Glusterd now uses the respective volumes' client-op-version during getspec requests. To achieve the above a new field in the vme table is introduced, client_option, this boolean field tells if the option is a client side option.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM: performance.nfs.* option values (which are of type boolean) are not validated during the stage phase of 'volume set'. The result - nfs graph generation fails during commit phase, AFTER the option and its (invalid) value have been placed in volinfo->dict. CAUSE: nfsperfxl_option_handler() - the function that validates the values of performance.nfs.* options - never receives the (key,value) pair that needs to be set, for validation during 'volume set' stage. FIX: In build_nfs_graph(), copy the (mod_)dict containing the (option,value) parameters into set_dict before attempting to build the client graph for the volume on which the operation is being performed. Of course, an easier way out would be to simply do a 'volume reset' and pretend nothing wrong happened!

| | | | | | | | | | | | | | | | | | | In a single node cluster, it is possible to deadlock on the "big lock", while restarting bricks. In glusterd_restart_bricks, we perform a glusterd_brick_connect, where we release the big lock in anticipation that glusterd_brick_rpc_notify could run in the same C stack (and deadlocking). So, in the restart code path, we could unlock before we have performed a lock on the big lock. To fix this, we need to take the big lock in the glusterd_launch_synctask 'thread' as well.

When a GET or HEAD request is made on a container, stat() system calls are made during the Python standard library method, os.walk, to determine if a given directory entry is another directory to recurse into, and then utils._update_list() will stat() each file to get it size, and finally utils.get_container_details_from_fs() will stat() each directory encountered. For most installations we have seen so far, we don't need the container listing to accurately return the size of all the objects in the container, so we can reduce the number of stat() system calls by not fetching the size of the object. For now, turn it off by default, and provide an /etc/swift/fs.conf configuration parameter to turn it back on: accurate_size_in_listing = yes The default for the above is "no".

* glusterd: big lock - a coarse-grained locking to prevent racesKrishnan Parthasarathi2013-04-1217-106/+692
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are primarily three lists that are part of glusterd process, that are concurrently accessed. Namely, priv->volumes, priv->peers and volinfo->bricks_list. Big-lock approach ----------------- WHAT IS IT? Big lock is a coarse-grained lock which protects all three lists, mentioned above, from racy access. HOW DOES IT WORK? At any given point in time, glusterd's thread(s) are in execution _iff_ there is a preceding, inbound network event. Of course, the sigwaiter thread and timer thread are exceptions. A network event is an external trigger to glusterd, via the epoll thread, in the form of POLLIN and POLLERR. As long as we take the big-lock at all such entry points and yield it when we are done, we are guaranteed that all the network events, accessing the global lists, are serialised. This amounts to holding the big lock at - all the handlers of all the actors in glusterd. (POLLIN) - all the cbks in glusterd. (POLLIN) - rpc_notify (DISCONNECT event), if we access/modify one of the three lists. (POLLERR) In the case of synctask'ized volume operations, we must remember that, if we held the big lock for the entire duration of the handler, we may block other non-synctask rpc actors from executing. For eg, volume-start would block in PMAP SIGNIN, if done incorrectly. To prevent this, we need to yield the big lock, when we yield the synctask, and reacquire on waking up of the synctask.

The situation seems to be when both subvolumes of a replica are "local" to glustershd, and in such cases glustershd is sensitive to the order in which the subvols come up. The core of the issue itself is that, without the patch (#4784), self-heal daemon completes the processing of index and no entries are left inside the xattrop index after a few seconds of volume start force. However with the patch, the stale "backing file" (against which index performs link()) is left. The likely reason is that an "INDEX" based crawl is not happening against the subvol when this patch is applied. Before #4784 patch, the order in which subvols came up was : [2013-04-09 22:55:35.117679] I [client-handshake.c:1456:client_setvolume_cbk] 0-patchy-client-0: Connected to 10.3.129.13:49156, attached to remote volume '/d/backends/brick1'. ...

The index in brick2 has the list of files/gfid to heal. It appears to be the case that when brick1 is the first subvol to be detected as coming up, somehow an INDEX based crawl is clearing all the index entries in brick2, but if brick2 comes up as the first subvol, then the backing file is left stale. Also, doing a "gluster volume heal full" seems to leave out stale backing files too. As the crawl is performed on the namespace and the backing file is never encountered there to get cleared out. So the interim (possibly permanent) fix is to have the script issue a regular self-heal command (and not a "full" one). The failure of the script itself is non-critical. The data files are all healed, and it is just the backing file which is left behind. The stale backing file too gets cleared in the next index based healing, either triggered manually or after 10mins.

* cluster/distribute: Ignore non-participating subvols for layout checksshishir gowda2013-04-094-27/+178
| | | | | | | | | | | | | | | | | | | | | | | When subvols-per-directory is < available subvols, then there are layouts which are not populated. This leads to incorrect identification of holes or overlaps. We need to ignore layouts, which have err == 0, and start == stop. In the current scenario (start == stop == 0). Additionally, in layout-merge, treat missing xattrs as err = 0. In case of missing layouts, anomalies will reset them. For any other valid subvoles, err != 0 in case of layouts being zeroed out. Also reverted back dht_selfheal_dir_xattr, which does layout calculation only on subvols which have errors.

* syncenv: be robust against spurious wake()sAnand Avati2013-04-091-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the current implementation, when the callers of synctasks perform a spurious wake() of a sleeping synctask (i.e, an extra wake() soon after a wake() which already woke up a yielded synctask), there is now a possibility of two sync threacs picking up the same synctask. This can result in a crash. The fix is to change ->slept = 0|1 and membership of synctask in runqueue atomically. Today we dequeue a task from the runqueue in syncenv_task(), but reset ->slept = 0 much later in synctask_switchto() in an unlocked manner -- which is safe, when there are no spurious wake()s. However, this opens a race window where, if a second wake() happens after the dequeue, but before setting ->slept = 0, it results in queueing the same synctask in the runqueue once again, and get picked up by a different synctask. This is has been diagnosed to be the crashes in the regression tests of http://review.gluster.org/4784. However that patch still has a spurious wake() [the trigger for this bug] which is yet to be fixed.

* afr: let eager-locking do its own overlap checksAnand Avati2013-04-054-56/+87
| | | | | | | | | | | | | | | | | | | | | | | | Today there is a non-obvious dependence of eager-locking on write-behind. The reason is that eager-locking works as long as the inheriting transaction has no overlaps with any of the transactions already in progress. While write-behind provides non-overlapping writes as a side-effect most of times (and only guarantees it when strict-write-ordering option is enabled, which is not on by default) eager-lock needs the behavior as a guarantee. This is leading to complex and unwanted checks for the presence of write-behind in the graph, for the simple task of checking for overlaps. This patch removes the interdependence between eager-locking and write-behind by making eager-locking do its own overlap checks with in-progress writes.

* posix: fix dangerous "sharing" of fd in readdir between two requestsAnand Avati2013-04-031-2/+17
| | | | | | | | | | | | | | | | | | | | | | | posix_fill_readdir() is a multi-step function which performs many readdir() calls, and expects the directory cursor to have not "seeked away" elsewhere between two successive iterations. Usually this is not a problem as each opendir() from an application has its own backend fd, and there is nobody else to "seek away" the directory cursor. However in case of NFS's use of anonymous fd, the same fd_t is shared between all NFS readdir requests, and two readdir loops can be executing in parallel on the same dir dragging away the cursor in a chaotic manner. The fix in this patch is to lock on the fd around the loop. Another approach could be to reimplement posix_fill_readdir() with a single getdents() call, but that's for another day.
