volume quota  {alert-time|soft-timeout|hard-timeout} {}
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.

mount/fuse: handle --gid-timeout=0 properly

2013-11-20T22:42:29+00:00

Fix the bug which was using the timeout value as a flag to indicate
if it was set (and hence would fail when timeout=0 would evaluate
as False)

glusterfsd, libgfapi: destroy the temporary graphs constructed for comparison

2013-10-04T04:32:43+00:00

* The new and the oldgraphs which have been constructed whenever there is
  a volfile change (either reconfigure of the existing graph or creating
  a new graph) for comparison should be freed. Otherwise frequent graph
  changes will lead to huge memory leak

logging: Expose set_log_file_path() in libglusterfs.

2013-09-24T19:00:54+00:00

This patch also changes the behavior of glfs_set_logging().
If logfile argument is not provided to glfs_set_logging(),
libgfapi uses set_log_file_path() to create a logfile.

fuse-bridge: enable --fopen-keep-cache based on FUSE_AUTO_INVAL_DATA.

2013-09-17T22:31:48+00:00

If kernel supports FUSE_AUTO_INVAL_DATA then it is safe(r) to turn on
--fopen-keep-cache mode by default. Users report significant improvement
in perf by enabling the mode.

glusterfsd: use-readdirp w/o arguments should not turn off readdirp

2013-09-10T04:41:41+00:00

`use-readdirp` has an optional argument in argp -
specifying just `--use-readdirp` command line should not
'turn off' readdirp, since that undermines the meaning
of such an argument.

glusterfsd: Round robin DNS should not be relied upon with

2013-09-06T22:56:34+00:00

config service availability for clients.

Backupvolfile server as it stands is slow and prone to errors
with mount script and its combination with RRDNS. Instead in
theory it should use all the available nodes in 'trusted pool'
by default (Right now we don't have a mechanism in place for
this)

Nevertheless this patch provides a scenario where a list of
volfile-server can be provided on command as shown below

-----------------------------------------------------------------
$ glusterfs -s server1 .. -s serverN --volfile-id= \
      
-----------------------------------------------------------------
                   OR
-----------------------------------------------------------------
$ mount -t glusterfs -obackup-volfile-servers=: \
      :...: :/ 
-----------------------------------------------------------------

Here ':' is used as a separator for mount script parsing

Now these will be remembered and recursively attempted for
fetching vol-file until exhausted. This would ensure that the
clients get 'volume' configs in a consistent manner avoiding the
need to poll through RRDNS.
