Hi,
I'm still testing my 2 node (dedicated) iSCSI gateway with ceph 12.2.12
before I dare to put it into production. I installed latest tcmu-runner
release (1.5.1) and (like before) I'm seeing that both nodes switch
exclusive locks for the disk images every 21 seconds. tcmu-runner logs
look like this:
2019-08-05 12:53:04.184 13742 [WARN] tcmu_notify_lock_lost:222
rbd/iscsi.test03: Async lock drop. Old state 1
2019-08-05 12:53:04.714 13742 [WARN] tcmu_rbd_lock:762 rbd/iscsi.test03:
Acquired exclusive lock.
2019-08-05 12:53:25.186 13742 [WARN] tcmu_notify_lock_lost:222
rbd/iscsi.test03: Async lock drop. Old state 1
2019-08-05 12:53:25.773 13742 [WARN] tcmu_rbd_lock:762 rbd/iscsi.test03:
Acquired exclusive lock.
Old state can sometimes be 0 or 2.
Is this expected behaviour?
What may be of interest in my case is that I use a dedicated
cluster_client_name in iscsi-gateway.cfg (not client.admin) and that I'm
running 2 separate targets in different IP networks.
thx for advice
matthias
