Is 3.7 stable? I have 60+ potential users and dont want to risk too
much. ;-)

The bricks are all on separate servers. On each is a XFS partition on a
single HDD (together with other partitions for system etc.). All in all
there are currently seven machines involved.

I just noticed that on all servers the
/var/log/glusterfs/etc-glusterfs-glusterd.vol.log is full of messages like

I assume this to be part of the problem…

Regards :-)
