Hi all,

We are seeing some oddness on a couple of our compute hosts that seems 
to be related to iSCSI. On a couple of our hosts I am seeing this error 
in the nova compute logs:

2020-10-27 18:56:14.814 31490 WARNING 
os_brick.initiator.connectors.iscsi 
[req-8613ae69-1661-49cf-8bdc-6fec875d01ba - - - - -] Couldn't find iscsi 
sessions because iscsiadm err: iscsiadm: could not read session 
targetname: 5
iscsiadm: could not find session info for session1707

That seems to also stop any instance on the compute host from being able 
to reboot.  Reboots seem to get accepted but the instance never 
completes and gets stuck in the reboot state:

2020-10-27 19:11:58.891 48612 INFO nova.compute.manager [-] [instance: 
c8079e85-4777-4615-9d5a-3d1151e11984] During sync_power_state the 
instance has a pending task (reboot_started_hard). Skip.
2020-10-27 19:11:58.891 48612 INFO nova.compute.manager [-] [instance: 
31128f26-910d-411f-98e0-c95dd36f4f0f] During sync_power_state the 
instance has a pending task (reboot_started_hard). Skip.

Does anyone know of a way to resolve this without rebooting the entire 
compute host? I can't see any other issues other than the fact there is 
this iSCSI error which in turn seems to stop nova from processing 
anything for any instance.

Any advice would be much appreciated.

Regards,
