to fail.
Added cbks for decompounder.

glusterd/geo-rep: Avoid started status check if same host

2016-06-13T14:40:04+00:00

After carrying out add-brick, session creation is carried out
again, to involve new brick in the session. This needs to be done,
even if the session is in Started state.

While involving slave uuid as part of a session, User is warned
if session is in Started state. This check needs to be avoided
if it is same slave host and session creation needs to be proceeded.

glusterd: fail volume delete if one of the node is down

2016-06-13T14:39:46+00:00

Backport of http://review.gluster.org/14681

Deleting a volume on a cluster where one of the node in the cluster is down is
buggy since once that node comes back the resync of the same volume will happen.
Till we bring in the soft delete feature tracked in
http://review.gluster.org/12963 this is a safe guard to block the volume
deletion.

Please note the test file which is backported from this commit has an issue
where we start the volume and then try to delete it which is anyway going to
fail. So the test actually doesn't validate the fix.
http://review.gluster.org/#/c/14693/ in master fixed the problem and the same is
ported as part of this commit as well.

glusterd/geo-rep: upgrade path when slave vol uuid involved

2016-06-13T10:36:56+00:00

slave volume uuid is involved in identifying a geo-replication
session.

This patch addresses upgrade path, where existing geo-rep session
is gracefully upgraded to involve slave volume uuid.

glusterd/snapshot: remove quota related options from snap volfile

2016-06-04T03:39:29+00:00

enabling inode-quota on a snapshot volume is unnecessary, because
snapshot is a read-only volume. So we don't need to enforce quota
on a snapshot volume.

This patch will remove the quota related options from snapshot
volfile.

glusterd/snapshot: Fix snapshot creation with geo-rep

2016-06-03T05:42:16+00:00

Backport of http://review.gluster.org/#/c/14595

The construction of path to geo-rep session directory
is broken with the commit "http://review.gluster.org/13111"
as it saves the slave volume uuid in 'gsync_slaves'
dictionary. This patch fixes the same.

Backport of http://review.gluster.org/#/c/14026/

Introduce cluster.favorite-child-policy which when enabled with
[ctime|mtime|size|majority], automatically heals files that are in
split-brian.

The majority policy will not pick a source if there is no majority.
The other three policies pick the first brick with a valid reply and
non-zero ctime/mtime/size as source.

cli/glusterd: add/remove brick fixes for arbiter volumes

2016-05-24T08:35:57+00:00

Backport of: http://review.gluster.org/14126

1.Provide a command to convert replica 2 volumes to arbiter volumes.
Existing self-heal logic will automatically heal the file hierarchy into
the arbiter brick, the progress of which can be monitored using the
heal info command.

Syntax: gluster volume add-brick  replica 3 arbiter 1


2. Add checks when removing bricks from arbiter volumes:
- When converting from arbiter to replica 2 volume, allow only arbiter
  brick to be removed.
- When converting from arbiter to plain distribute volume, allow only if
  arbiter is one of the bricks that is removed.

3. Some clean-up:
- Use GD_MSG_DICT_GET_SUCCESS instead of GD_MSG_DICT_GET_FAILED to
log messages that are not failures.
- Remove unused variable `brick_list`
- Move 'brickinfo->group' related functions to glusted-utils.
