Hello,
I have 3 node HCI cluster with oVirt 4.4.6 and CentOS8.
For time to time (I belive) random brick on random host goes down
because health-check. It looks like
[root@ovirt-hci02 ~]# grep "posix_health_check" /var/log/glusterfs/bricks/*
/var/log/glusterfs/bricks/gluster_bricks-vms2-vms2.log:[2021-07-07

I cannot link these errors to any storage/fs issue (in dmesg or
/var/log/messages), brick devices looks healthy (smartd).
I can force start brick with
gluster volume start vms|engine force
and after some healing all works fine for few days
Did anybody observe this behavior?
vms volume has this structure (two bricks per host, each is separate
JBOD ssd disk), engine volume has one brick on each host...
gluster volume info vms
