[Gluster-users] Self-Heal Daemon not Running

[Andrew Lau]

Found the BZ https://bugzilla.redhat.com/show_bug.cgi?id=960190 - so I
restarted one of the volumes and it seems to have restarted the all daemons
again.

Self heal started again, but I seem to have split-brain issues everywhere.
There's over 100 different entries on each node, what's the best way to
restore this now? Short of having to manually go through and delete 200+
files. It looks like a full split brain as the file sizes on the different
nodes are out of balance by about 100GB or so.

Any suggestions would be much appreciated!

Cheers.
