afr: Automagic unsplit-brain by [ctime|mtime|size|majority]

2016-05-27T14:56:37+00:00

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.

cluster/afr: Don't let NFS cache stat after writes

2016-05-14T14:30:21+00:00

Problem:
Afr does post-ops after write but the stat buffer it unwinds is at the
time of write, so if nfs client caches this, it will see different
ctime when it does stat on it after post-op is done. From NFS client's
perspective it thinks the file is changed. Tar which depends on this
to be correct keeps giving 'file changed as we read it' warning.
If Afr instead has to choose to unwind after post-op, eager-lock,
delayed-post-op will have to be disabled which will lead to bad
performance for all write usecases.

Fix:
Don't let client cache stat after write.

cluster/afr: Do heals with shd pid

2016-05-14T14:14:37+00:00

Multi-threaded healing doesn't create synctask with shd pid, this
leads to healing problems when quota exceeds.
