I am curious about what is happening with your iscsi configuration
Is this a new iscsi config or something that has just cropped up ?
We are using/have been using vmware for 5+ years with iscsi
We are using the kernel iscsi vs tcmu
Do you mean you are using kernel target, not the ceph-iscsi/tcmu-runner
in user space, right ?
We are running ALUA and all datastores are setup as RR
We routinely reboot the iscsi gateways - during patching and updates and the storage migrates to and from all servers without issue
We usually wait about 10 minutes before a gateway restart, so there is not an outage
It has been extremely stable for us
Thanks Joe

Hi Xiubo,
Thx for pointing me into the right direction. All involved esx host
seem to use the correct policy. I am going to detach the LUN on each
host one by one until i found the host causing the problem.
From the logs it means the client was switching the path in turn.
BTW, what's policy are you using ?
Thanks

Hi Stolte,
For the VMware config could you refer to :
https://docs.ceph.com/en/latest/rbd/iscsi-initiator-esx/ ?
What's the "Path Selection Policy with ALUA" you are using ? The
ceph-iscsi couldn't implement the real AA, so if you use the RR I
think it will be like this.

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

At the same time there are these log entries in ceph.audit.logs:

]': 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/>)
