* glusterd: Allow bumping up the cluster op-versionKaushal M2014-05-062-0/+77
| | | | | | | | | | | | | | | | | | | | | | | | | This patch allows a user to bump up the cluster op-version by doing # gluster volume set all cluster.op-version <OP-VERSION> The op-version will be bumped only if - all the peers in the cluster support it, and - the new op-version is greater than the current cluster op-version This set operation will not do any other change other than changing and saving the cluster op-version in the glusterd.info file. It will NOT, - change any existing volume - add the option to the global options list - fix the cluster op-version to the given version, it can be bumped up by other volume set commands.

* glusterd/snashot: Perform missed snap createsAvra Sengupta2014-05-064-145/+589
| | | | | | | | | | | | | | | | | | | | | | | | | When a brick is started, and the glusterfsd process requests for volfile, the brick_name is sent in the req dict. In glusterd, after fetching the spec the brick_name is looked up in the missed_snap_list, and any missing snap creates on the same brick are performed. After this, the glusterd responds back with the specfile. Also collate brick data from the node's hosting the bricks during restore. In case the data is absent, the local node's data is used. This is needed to ensure that, during a restore we collect the information created when a missed snap create is performed.

* glusterd : Volname, brickpath & volfpath length validationAtin Mukherjee2014-05-036-21/+61
| | | | | | | | | | | | | | | | | | | | | | | | While creating a volume and adding a brick validation for _POSIX_PATH_MAX is done on absolute pathname instead of relative pathname due to which a brickpath having less than _POSIX_PATH_MAX may also fail the validation if the directory length is greater than (_POSIX_PATH_MAX -strlen(brickpath/volume name). Also this fix addresses one cli response message correction which says the volume file is too long instead of brick path is too long (when brickpath length validation doesn't fail and vol file length validation fails.) It is also important to note that with the current design of volfile naming, it can not be guranteed that volname and brickpath can have max of _POSIX_PATH_MAX characters.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. gluster volume set nfs-ganesha.enable ON/OFF If the option is set to ON, the volume field in the nfs-ganesha configuartion file is edited. Gluster-nfs is disabled on that volume and the volume is exported using nfs-ganesha. 2.gluster volume set nfs-ganesha.host IP This is used to provide the IP of the nfs-ganesha host. Note : nfs-ganesha.host MUST be set before using nfs-ganesha.enable ON The switch from gluster-nfs to nfs-ganesha is mostly done by the hook-scripts in the post phase of the 'set' option. As a result, gluster volume reset does not function as it is expected to. By default, nfs-ganesha will be set to off but the process will not be killed. Hence, a few changes have to be made post 'reset' option as well. Those changes also have been added.

A new gluster rpc program for ping is introduced. The ping timer is only started for peers that have this new program. The deafult glusterd ping timeout is 30 seconds. It is configurable by setting the option 'ping-timeout' in glusterd.vol . Also, this patch introduces changes in the glusterd-handshake path. The client programs for a peer are now set in the callback of dump_versions, for both the older handshake and the newer op-version handshake. This is the only place in the handshake process where we know what programs a peer supports.

If so, then glusterd_v3_mgmt framework is not called, as reading information from local node is enough. This Patch also fixes "Assertion failed: volname" while doing the system config change when snap create was in progress.

* glusterd/snapshot: Compare and update snapshots during peer handshakeAvra Sengupta2014-04-287-126/+984
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During a peer-handshake, after the volumes have synced, and the list of missed snapshots have synced, the node will perform the pending deletes and restores on this list. At this point, the current snapshot list in the node will be updated, and hence in case of conflicts arising during snapshot handshake, the peer hosting the bricks will be given precedence Likewise, if there will be a conflict, and both peers will be in the same state, i.e either both would be hosting bricks or both would not be hosting bricks, then a decision can't be taken and a peer-reject will happen. glusterd_compare_and_update_snap() implements the following algorithm to perform the above task: Step 1: Start. Step 2: Check if the peer is missing a delete on the said snap. If yes, goto step 6. Step 3: Check if there is a conflict between the peer's data and the local snap. If no, goto step 5. Step 4: As there is a conflict, check if both the peer and the local nodes are hosting bricks. Based on the results perform the following: Peer Hosts Bricks Local Node Hosts Bricks Action Yes Yes Goto Step 7 No No Goto Step 7 Yes No Goto Step 8 No Yes Goto Step 6 Step 5: Check if the local node is missing the peer's data. If yes, goto step 9. Step 6: It's a no-op. Goto step 10 Step 7: Peer Reject. Goto step 10 Step 8: Delete local node's data. Step 9: Accept Peer Data.

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 every 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.
