[Gluster-users] Upgrade 10.4 -> 11.1 making problems

Morning,
a few bad apples - but which ones? Checked glustershd.log on the "bad"
server and counted todays "gfid mismatch" entries (2800 in total):
44 <gfid:faeea007-2f41-4a72-959f-e9e14e6a9ea4>/212>,
44 <gfid:faeea007-2f41-4a72-959f-e9e14e6a9ea4>/174>,
44 <gfid:d5c6d7b9-f217-4cc9-a664-448d034e74c2>/94037803>,
44 <gfid:d263ecc2-9c21-455c-9ba9-5a999c03adce>/94066216>,
44 <gfid:cbfd5d46-d580-4845-a544-e46fd82c1758>/249771609>,
44 <gfid:aecf217a-0797-43d1-9481-422a8ac8a5d0>/64235523>,
44 <gfid:a701d47b-b3fb-4e7e-bbfb-bc3e19632867>/185>,
etc. But as i said, these are pretty new and didn't appear when the
volume/servers started missbehaving. Are there scripts/snippets
available how one could handle this?
Healing would be very painful for the running system (still connected,
but not very long anymore), as there surely are 4-5 million entries to
be healed. I can't do this now - maybe, when the replacement is in
productive state, one could give it a try.
Thx,
Hubert
