* glusterd/snapshot: Recording the snapshots missed in each brick.Avra Sengupta2014-04-021-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Persisting missing snapshot info on disk as well as in memory in the following format: -------------NODE-UUID--------------:---------SNAP-UUID--------------=BRICKNUM:-------BRICKPATH--------:OPERATION:STATUS 927cb5fe-63da-48f5-82f6-e6a09ddc81c4:a17b4fe42c5a45f7a916438643edaa13= 3 :/brick/brick-dirs/brick3: 1 : 1 927cb5fe-63da-48f5-82f6-e6a09ddc81c4:a17b4fe42c5a45f7a916438643edaa13= 3 :/brick/brick-dirs/brick3: 3 : 1 927cb5fe-63da-48f5-82f6-e6a09ddc81c4:83a3cc05453b46b2a7eda4c9a9208638= 3 :/brick/brick-dirs/brick3: 1 : 1 This data will be stored on disk at /var/lib/glusterd/snaps/missed_snaps_list In memory we maintain the data as a list of glusterd_missed_snap_info in conf, the key for this list are the first two fields, i.e NODE-UUID:SNAP-UUID. For every NODE-UUID:SNAP-UUID, there can be multiple operations missed on multiple bricks. So we maintain a list of glusterd_snap_op_t for evert node of glusterd_missed_snap_info This list is maintained or updated during snapshot create, delete, and restore operations which are the only operations that if missed, are recorded in this list. During snapshot create, if a node is down, or a brick is down, we don't receive their mount point infos. snap_status of such bricks is marked as -1, and their brick details are added to this list. During snapshot delete, we check from originator node, if any other nodes, holding bricks of the said snap are down. Those are also added to the list. Also if the node is up, but the snapshot was pending for a snap brick, and its snap_status is -1, we add that to the list too. When a subsequent delete entry is processed for an already existing create entry, we just mark the create entries status as done (2), and don't add the delete entry to the list. During snapshot restore, we check from originator node, if any other nodes, holding bricks of the said snap are down. Those are also added to the list. Also if the node is up, but the snapshot was pending for a snap brick, and its snap_status is -1, we add that to the list too.

* glusterd: remove-brick:Allow simultaneous removal of multiple subvolumes.Ravishankar N2013-08-131-1/+2
| | | | | | | | | | | | | | | | | Currently, remove-brick supports removal of only one distributed stripe/ replica pair at a time. Fix it to support removal of multiple pairs. This is consistent with add-brick behaviour which supports adding multiple stripe/replica pairs simultaneously. Removal is successful irrespective of the order of the bricks given at the CLI, as long as the bricks are from the same subvolume(s).

* glusterd: Run post hooks on a different threadKrishnan Parthasarathi2012-05-291-1/+3
| | | | | | | | | | | | | | | | | | | | This change ensures post hooks can 'wait' if need be and _not_ prevent glusterd from being able to run other operations meanwhile. Also ensures that post hook scripts are 'serialized' between transactions. ie, post hook scripts of txn1 are completed before post hook scripts of txn2 are started, where txn1 happens before txn2.

* glusterd / cli: mount-broker serviceCsaba Henk2011-09-121-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mountbroker is configured in glusterd volfile through a DSL which is restriced enough to be able to appear in the role of the value of a volfile knob. Basically the DSL describes set-theorical requirements against the option set which is sent by the cli (in the hope of getting a mount with these options). If the requirements meet and the volume id and the uid who is to "own" the mount can be unambigously deduced from the given request, glusterd does the mount with the given parameters. The use case of geo-replication is sugared by means of volume options which then generate a complete mount-broker option set. Demo: - add the following option to your glusterd volfile: option mountbroker-root /tmp/mbr option mountbroker.fool EQL(volfile-id=pop*|user-map-root=*|volfile-server=localhost)&MEET(user-map-root=john|user-map-root=jane) - before starting glusterd, create /tmp/mbr owned by root with mode 0755 - with cli, do $ gluster system:: mount fool volfile-id=pop33 user-map-root=jane volfile-server=localhost - on succesful completion (volume pop33 exists and is started, jane is a valid username), the mount path will be echoed to you - you can get rid of the mount by $ gluster system:: umount <mount-path> Change-Id: I629cf64add0a45500d05becc3316f67cdb5b42ff BUG: 3482 Reviewed-on: http://review.gluster.com/128 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vijay@gluster.com>
