<p>Hi all,</p>
<p>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:</p>
<p>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<br>
iscsiadm: could not find session info for session1707</p>
<p>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:</p>
<p>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.<br>
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.<br>
</p>
<p>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.</p>
<p>Any advice would be much appreciated.</p>
<p>Regards,<br>
