* glusterd-volgen: Improve volume op-versions calculationKaushal M2013-05-311-0/+11
| | | | | | | | | | | | | | | | | | Volume op-versions calculations now take into account if an option, a. enables/disables an xlator, or b. is a boolean option. This prevents op-versions from being updated when a feature is disabled. Also, correctly close the dynamically loaded xlators in xlator_volopt_dynload() and prevent leaks.

* glusterd: Give up biglock during rpc conn cleanupKrishnan Parthasarathi2013-05-231-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | glusterd could deadlock after a peer-detach command as follows, 1) glusterd_friend_cleanup function 'flushes' out messages in the rpc layer's queue, that haven't received a response. At this point, glusterd has already acquired the big lock. 2) The side-effect of flushing out the messages is that the corresponding call backs are called. Call backs themselves are executed after acquiring the big lock. This results in the big lock being acquired in a nested manner (in the same thread), which causes a deadlock. This can also happen during brick/NFS/SHD disconnect in volume-stop.

| | | | | | | | | | | | | | | The restarting of bricks has been deffered until the cluster 'stabilizes' itself volumes' view. Since glusterd_spawn_daemons is executed everytime a peer 'joins' the cluster, it may inadvertently restart bricks that were taken offline for say, maintenance purposes. This fix avoids that.

* glusterd: Introduce volume op-versionsKaushal M2013-04-261-0/+42
| | | | | | | | | | | | | | | | | | | | | | | 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.

* glusterd: big lock - a coarse-grained locking to prevent racesKrishnan Parthasarathi2013-04-121-9/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* glusterd: Mark vol as deleted by renaming voldir before cleaning up the storeKrutika Dhananjay2013-03-111-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM: During 'volume delete', when glusterd fails to erase all information about a volume from the backend store (for instance because rmdir() failed on non-empty directories), not only does volume delete fail on that node, but also subsequent attempts to restart glusterd fail because the volume store is left in an inconsistent state. FIX: Rename the volume directory path to a new location <working-dir>/trash/<volume-id>.deleted, and then go on to clean up its contents. The volume is considered deleted once rename() succeeds, irrespective of whether the cleanup succeeds or not.

* glusterd: fix segfault on volume status detailLars Ellenberg2013-03-081-9/+11
| | | | | | | | | | | | | | | | | | | | | | | If for some reason glusterd_get_brick_root() fails, it frees the gf_strdup'ed *mount_point in its own error path, and returns -1. Unfortunately it already had assigned that pointer value to the output argument, the caller function glusterd_add_brick_detail() sees a non-NULL pointer, and free() again: segfault. Could be fixed with a one-liner (*mount_point = NULL) in the error path, but I think glusterd_get_brick_root() should only assign to the output argument once all checks passed, so I use a local temporary pointer, which increases the patch a bit.

* glusterd: allow multiple instances of glusterd on one machineJeff Darcy2013-02-211-0/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is needed to support automated testing of cluster-communication features such as probing and quorum. In order to use this, you need to do the following preparatory steps. * Copy /var/lib/glusterd to another directory for each virtual host * Ensure that each virtual host has a different UUID in its glusterd.info Now you can start each copy of glusterd with the following xlator-options. * management.transport.socket.bind-address=$ip_address * management.working-directory=$unique_working_directory You can use 127.x.y.z addresses for binding without needing to assign them to interfaces explicitly. Note that you must use addresses, not names, because of some stuff in the socket code that's not worth fixing just for this usage, but after that you can use names in /etc/hosts instead. At this point you can issue CLI commands to a specific glusterd using the --remote-host option. So far probe, volume create/start/stop, mount, and basic I/O all seem to work as expected with multiple instances.

* glusterd, cli: Task id's for async tasksKaushal M2012-12-191-56/+209
| | | | | | | | | | | | | | | | | | | | | | This patch introduces task-id's for async tasks like rebalance, remove-brick and replace-brick. An id is generated for each task when it is started and displayed to the user in cli output. The status of running tasks is also included in the output of "volume status" along with its id, so that a user can easily track the progress of an async task. Also, * added tests for this feature into the regression test suite. * added a python script for creating files, 'create-files.py', courtesy Vijaykumar Koppad (vkoppad@redhat.com) into the test suite.

* mgmt/glusterd: Consider nodesvc to be running after onlinePranith Kumar K2012-11-291-10/+12
| | | | | | | | | | | | | | | | | | | | | Definition of online in the message below is that the RPC_CLNT_CONNECT event arrives for the nfs/self-heal-daemon process. For automated tests, sometimes the script needs to wait until self-heal-daemon comes online, so that the relevant commands can be executed. Gluster volume status before this change printed whether the self-heal-daemon is running or not based on the lock availability on the pidfile. But there is a small window where the lock on pid file is present but the process is still not online. So the commands that were depending on this kept failing in the test script.
