glusterd/mountbroker: enhance mountbroker-geo-replication.* option to take multiple volumes

2012-03-14T17:59:01+00:00

Comma can be used in the value of a "mountbroker-geo-replication.*" option
with semantics as of these examples:

  option mountbroker-geo-replication.foolabel vol1,vol2,vol3:geouser

and

  option mountbroker-geo-replication.geouser vol1,vol2,vol3

will allow geouser to mount any of the volumes vol{1,2,3} with params of a
geo-rep aux mount under label foolabel, resp. geouser

Also fix memleak in parsing of this option.

glusterd: Fix brick op to prevent glusterd crashing

2012-03-14T16:51:13+00:00

Was building payload only for node types GD_NODE_BRICK & GD_NODE_NFS.
Payload wasn't being built for nodes GD_NODE_SHD & GD_NODE_REBALANCE, which made
glusterd crash when those operations were performed.

Also fix a compile warning.

cli, glusterd, nfs: "volume status|profile|top" for nfs servers

2012-03-14T09:27:42+00:00

Enables usage of volume monitoring operations "volume status", "volume top" and
"volume profile" for nfs servers. These operations can be performed on
nfs-servers  by passing "nfs" as an option in cli. The output is similar to the
normal brick outputs for these commands.

The new syntaxes for the changed commands are as below,
 #gluster volume profile  {start|info|stop} [nfs]
 #gluster volume top  {[open|read|write|opendir|readdir [nfs]]
               |[read-perf|write-perf [nfs|{bs  count }]]}
               [brick ] [list-cnt ]
 #gluster volume status [all |  [nfs|]]
          [detail|clients|mem|inode|fd|callpool]

glusterd: Peer(s) mustn't send updates about members not yet in cluster

2012-03-12T12:19:23+00:00

Also, peerinfo is added to peers list synchoronous with the request triggering
it. This ensures that atmost one request sees that the peer (in question) is
not in peers list.  Earlier, 'concurrent' handle_friend_update requests would
see that a particular peer is not in the peers list yet, as the addition of the
'peer' into the list happened asynchronously, on the 'connect' event of the
'peer'.
