* glusterd: Improve error logging when a brick from an old volume gets re-usedNiels de Vos2013-03-221-2/+7
| | | | | | | | | | | | | | | | | | | The error message when creating a volume that contains a brick with certain xatts set on a parent directory is unclear. Users do not understand '... or a prefix of it is already part of a volume'. Most users check the final directory that is used for a brick, but not its parents. It would be helpful to present the user with the actual directory that is preventing the volume to use the brick.

* 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.

| | | | | | | | | | | | | | | | | | | | When specifying transport.socket.bind-address option, only the glusterd daemon uses this address. But glusterfsd still working with the default localhost address. For instance, when we want to use an IPV6 specific address we will want that all process use that specified address even glusterfsd. To handle this change we just need to replace the fixed address “localhost” to the specified brick address “brickinfo->hostname” Change-Id: I540d30e6c155f71379a1cf1c0b459ac00faeb62c BUG: 865327 Signed-off-by: Lahoucine BENLAHMR <lahoucine@benlahmr.com> Reviewed-on: http://review.gluster.org/3889 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>

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.

* glusterd: Fix to log command status at the appropriate timeKrutika Dhananjay2012-09-201-1/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM: In the existing implementation, the success/failure of execution of a command is decided (and logged) in glusterd handler functions. Strictly speaking, the logging mechanism must take into account what course the command takes within the state machine before concluding whether it succeeded or failed. FIX: This patch attempts to fix the above issue for vol commands. The format of the log message is as follows: for failure: <command string> : FAILED : <cause of failure> for success: <command string> : SUCCESS APPROACH (in a nutshell): * The command string is packed into dict at cli and sent to glusterd. * glusterd logs the command status just before doing a "submit_reply", which is called (either directly or indirectly via a call to glusterd_op_cli_send_response) at 2 places for every vol command: i. in handler functions, and ii. in glusterd_op_txn_complete In short, the failure of a command in the handler implies the command has indeed failed. However, its success in the handler does NOT necessarily mean the command succeeded/will succeed.
