cluster/afr : Prevent inode-evict during split-brain resolution

2015-05-09T08:54:56+00:00

        Backport of: http://review.gluster.org/#/c/10134/

1) Provided setfattr command to set timeout for split-brain
choice.

2) If split-brain inspection/resolution is being done
from the mount for a file, ref the inode when
split-brain-choice is set.
This inode will be unconditionally unref-ed after timeout
seconds set by the user/default otherwise.

3) Updated the doc and testcase to reflect the changes.

cluster/afr : enable inspection & resolution of files in split-brain

2015-03-19T13:33:12+00:00

Part 2/2 patch to enable users analyze and resolve
split-brain.

This patch enables :
1) Users to inspect the files in data and metadata split-brain.
2) Resolve the split-brain.
Both using a series of setfattr commands.

Consider a volume "test" with 2 bricks.

1) To inspect a file f1:
setfattr -n replica.split-brain-choice -v test-client-0 f1
        After the execution of this command, if no read_subvol
is found, reads will be served from test-client-0 (corresponding
to brick-0).

2) To resolve split-brain :
setfattr -n replica.split-brain-heal-finalize -v test-client-0 f1
        Execution of this command will lead to the resolution
of data and metadata split-brain with subvol mentioned in the
command (test-client-0 here) as the source and the rest as sink.
