glusterd: Fixed glusterd_brick_create_path algo.

2012-05-19T10:27:20+00:00

- check if any prefix of the brick path has "trusted.gfid"
  or "trusted.glusterfs.volume-id" set.
- set trusted.glusterfs.volume-id on the bricks as soon as
  its induction into the volume is settled. Earlier, the setting of
  "volume-id" used to happen during the first run of the brick process,
  leaving of window for bricks part of one volume to be (ab)used by another
  volume inadvertently.
- removed creation of brick directory (if missing), during start volume force.
  This is to avoid directory creation as part 'force'ful starting of volume
  and leave the responsibility with the user, who understands the
  'availability' of the export directory (brick) better.

mgmt/glusterd: Avoid re-starting nfs unconditionally.

2012-05-09T05:14:01+00:00

NFS server is restarted unconditionally when a volume option is
configured through the set interface. This patch prevents restart
of NFS server when operations are performed on translators that
are not part of the NFS graph.

This does not prevent re-start of a NFS server when an option
corresponding to a translator that is part of the NFS graph is
re-configured.

rebalance: handshake_event_notify to make fsd talk to glusterd

2012-04-25T11:05:35+00:00

Event_notify can be used by others to communicate with glusterd.
A cbk event is also added for future use.

req has a op, and dict.
rsp has op_ret, op_errno, and dict.

With this, rebalance process can update the status before
exiting.

glusterd: Added volume-id to 'op' dictionary

2012-04-13T06:07:08+00:00

Volume-id passed in op dictionary would help detect possible split brains
among peers in a cluster. The idea is to check if the volume's id and
the vol-id that was passed are equal.
ie, same volume name, but different volume id indicate that glusterd
'metadata' of one of the participating peers is stale or there is
a split brain.

This is over and above the existing checksum based validation of peer
supplied cluster 'metadata' (ie, volume info file).

glusterd: Added init scripts like interface for gluster commands

2012-03-31T12:15:08+00:00

Directories to hold the scripts mentioned above would be created for each
gluster command under glusterd's 'working dir' as follows:
(eg.)
/hooks/version/create/pre

/hooks/version/create/post

where, version corresponds to the version of hook scripts.

The scripts beginning with 'S' under the above directories would be run before
(pre) and after (post) the volume created. The scripts would receive a command
line argument as below:
--volname=

This can be optionally used  by the script.

glusterd: Fixed replace-brick commit_force algo.

2012-03-27T17:34:13+00:00

- commit force subcommand of replace-brick (rb) should be allowed
  even if source brick is (irrecoverably) offline.
- modified rb_timer to be active only for start subcommand. This is
  important since, the rb timer event relies on src_brick and dst_brick
  objects to be 'alive' when it 'happens'. In the case of
  abort/commit/commit force it is very likely that src_brick and/or
  dst_brick objects could have been destroyed.

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]
