[Gluster-users] Problem with self-heal

Hi there

Not sure whether this is related, but we see the same problem with
glusterfs-3.4(.2). Several files are listed as being healed but they never
finish and checksums are identical.
We had some problems with NTP, meaning that the clocks on the nodes diverged by
a couple of seconds. I suspect this may be the root cause for it, but I could
not do any further tests and the files are still in the same state (self-healing).

Interestingly there are other threads describing this sort of problem, but
nothing came out so far.
