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.
