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