[Gluster-users] Data on gluster volume gone

This logfile didn't have any logs about heal. Could you find the same file
on the other node as well and attach it to the mail-thread? We should also
see the mount logs once to confirm replication did something or not.
Otherwise we should see the brick logs. Instead of checking it iteratively,
could you tar /var/log/glusterfs on both the nodes and give links to these
files so that we can download and check what might have happened?
