Look your clients at mon sessions: We upgraded our Ceph cluster from Hammer to Luminous and it is running
fine. Post upgrade we live migrated all our Openstack instances (not 100%
sure). Currently we see 1658 clients still on Hammer version. To track the
clients we increased the debugging of debug_mon=10/10, debug_ms=1/5,
debug_monc=5/20 on all three monitors and looking at all three monitor logs
at /var/log/ceph/mon.<id>.log and grepping for hammer and 0x81dff8eeacfffb but
not seeing anything in logs even after hours of waiting.
Earlier in our other clusters it used to show in logs from which Openstack
compute node it is originating from. Am I missing something or do I need
to add more logging or need to check a different log on all three ceph
monitor nodes?
`ceph daemon /var/run/ceph/ceph-mon.ceph-mon0.asok sessions | grep hammer | awk '{print $2}'`
