cluster/afr: split-brain resolution CLI
Extend the AFR heal command to include automated split-brain resolution.
This patch [3/3] is the final patch for afr automated split-brain resolution
implementation.
"gluster volume heal <VOLNAME> [full | statistics [heal-count [replica
<HOSTNAME:BRICKNAME>]] |info [healed | heal-failed | split-brain]| split-brain
{bigger-file <FILE> |source-brick <HOSTNAME:BRICKNAME> [<FILE>]}]"
The new additions being:
1.gluster volume heal <VOLNAME> split-brain bigger-file <FILE>
Locates the replica containing the FILE, selects bigger-file as source and
completes heal.
2.gluster volume heal <VOLNAME> split-brain source-brick <HOSTNAME:BRICKNAME>
<FILE>
Selects <FILE> present in <HOSTNAME:BRICKNAME> as source and completes heal.
3.gluster volume heal <VOLNAME> split-brain <HOSTNAME:BRICKNAME>
Selects all split-brained files in <HOSTNAME:BRICKNAME> as source and completes
heal.
Note: <FILE> can be either the full file name as seen from the root of the
volume (or) the gfid-string representation of the file, which sometimes gets
displayed in the heal info command's output.
Entry/gfid split-brain resolution is not supported.
Example can be found in the test case.
