* glusterd/snapshot: Recording the snapshots missed in each brick.Avra Sengupta2014-04-0211-62/+1203
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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/snapshot: Making snap operations crash consistentAvra Sengupta2014-04-027-53/+206
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the events of a volume's brick being down, or a node being down, making snap ops like create, delete, restore, and status crash consistent. Marking snap status of snap bricks which were not snapshotted because the volume brick was down as -1, and not starting those snap bricks till the snapshot is taken. During delete bypassing lvm snapshot remove for snap bricks whose snap status is -1 During restore bypass replacing xattrs on the snapshot bricks whose snap status is -1. Also bumping restored volume's version so as to handle nodes being down. On handshake of a restored volume, passing brick's snap_status as well. During snapshot status of the non-snapshotted brick details display "N/A". If a node is down, the entry itself will not be displayed.

* glusterd/mgmt_v3 locks: Handling different entities with mgmt_v3_locks.Avra Sengupta2014-03-077-43/+111
| | | | | | | | | | | | | | | | | Within the same namespace allowing mgmt_v3 lock engine to handle entities of valid types. Postfixing the element's name with the entity type allows us to perform locking operations on different elements of different entitites at the same time. For example: A volume named test, will acquire a lock on the name test_vol, while a snap named test will acquire lock on the name test_snap, and thus be allowed to co-exist in the same namespace.

* gluster/snapshot: Create missing backend snapshot folderRajesh Joseph2014-03-073-47/+79
| | | | | | | | | | | | | | | | Snapshot volume bricks are mounted under /var/run/gluster/snaps folder. In the latest machines /var/run is a symbolic link to /run folder. In such cases if we use /var/run then there would be mismatch between mtab entry for the mount and the folder where we actually mount. Therefore this patch will get the correct folder and also create it if the folder is missing.
