Hi guys,
we are using ceph-iscsi to provide block storage for Microsoft Exchange and vmware vsphere. Ceph docs state that you need to configure Windows iSCSI Initatior for fail-over-only but there is no such point for vmware. In my tcmu-runner logs on both ceph-iscsi gateways I see the following:
2022-12-12 10:36:06.978 33789 [WARN] tcmu_notify_lock_lost:222 rbd/mailbox.vmdk_junet_sata: Async lock drop. Old state 1

2022-12-12 10:36:11.104 33789 [WARN] tcmu_notify_lock_lost:222 rbd/mailbox.vmdk_junet_sata: Async lock drop. Old state 1
2022-12-12 10:36:11.106 33789 [INFO] alua_implicit_transition:570 rbd/mailbox.vmdk_junet_sata: Starting lock acquisition operation.
At the same time there are these log entries in ceph.audit.logs:
2022-12-12T10:36:06.731621+0100 mon.mon-k2-1 (mon.1) 3407851 : audit [INF] from='client.? 10.100.8.55:0/2392201639' entity='client.admin' cmd=[{"prefix": "osd blocklist", "blocklistop": "add", "addr": "10

]': finished
Can someone explaint to me, what is happening? Why are the gateways blacklisting each other? All involved daemons are running Version 16.2.10. ceph-iscsi gateways are running on Ubuntu 20.04 with ceph-isci package from the Ubuntu repo (all other packers came directly from ceph.com <http://ceph.com/>)
