cli: Addition of new child elements under brick in volume info xml.

2014-01-17T10:12:55+00:00

Added new child elements; name and hostUuid under brick in
volume info xml where name and host uuid of the bricks are stored,
This does not break backward compatibility as the old value under
brick is not removed.

glusterd: Aggregate tasks status in 'volume status [tasks]'

2013-12-23T14:56:34+00:00

        Backport of http://review.gluster.org/6230
Previously, glusterd used to just send back the local status of a task
in a 'volume status [tasks]' command. As the rebalance operation is
distributed and asynchronus, this meant that different peers could give
different status values for a rebalance or remove-brick task.

With this patch, all the peers will send back the tasks status as a part
of the 'volume status' commit op, and the origin peer will aggregate
these to arrive at a final status for the task.

The aggregation is only done for rebalance or remove-brick tasks. The
replace-brick task will have the same status on all the peers (see
comment in glusterd_volume_status_aggregate_tasks_status() for more
information) and need not be aggregated.

The rebalance process has 5 states,
 NOT_STARTED - rebalance process has not been started on this node
 STARTED - rebalance process has been started and is still running
 STOPPED - rebalance process was stopped by a 'rebalance/remove-brick
           stop' command
 COMPLETED - rebalance process completed successfully
 FAILED - rebalance process failed to complete successfully
The aggregation is done using the following precedence,
 STARTED > FAILED > STOPPED > COMPLETED > NOT_STARTED

The new changes make the 'volume status tasks' command a distributed
command as we need to get the task status from all peers.

The following tests were performed,
- Start a remove-brick task and do a status command on a peer which
  doesn't have the brick being removed. The remove-brick status was
  given correctly as 'in progress' and 'completed', instead of 'not
  started'
- Start a rebalance task, run the status command. The status moved to
  'completed' only after rebalance completed on all nodes.

Also, change the CLI xml output code for rebalance status to use the
same algorithm for status aggregation.

volume status [all |  [nfs|shd||quotad]] [detail|clients|mem|inode|fd|callpool]
volume statedump  [nfs|quotad] [all|mem|iobuf|callpool|priv|fd|inode|history]

glusterd changes:
=================
* Quota limits are now set as extended attributes by glusterd from
  the aux mount created by the cli.
* The gfids of the directories on which quota limits are set
  for a given volume are stored in
  /var/lib/glusterd/vols//quota.conf file in binary format,
  and whose cksum and version is stored in
  /var/lib/glusterd/vols//quota.cksum.

cli: List only nodes which have rebalance started in rebalance status

2013-11-20T19:30:25+00:00

Listing the nodes on which rebalance hasn't been started is just giving
out extraneous information.

Also, refactor the rebalance status printing code into a single function
and use it for both rebalance and remove-brick status.
