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.
