Hello,

You have to remove the ceph lock:

$1 = pool

$2 = volume name

read -r -a vars <<< $(rbd -p $1 lock list $2 | tail -1) rbd -p $1 lock remove $2 "${vars[1]} ${vars[2]}" ${vars[0]}

Best regards,

Romain

I saw your message on the website http://lists.openstack.org/pipermail/openstack-discuss/2019-April/005635.htm... . And i have been troubled by the same problem for a long time . I tried to change the parameters resume_guests_state_on_host_boot=True and instance_usage_audit=True in the nova.conf ,but it didn't work . I wonder if you have solved this problem, looking forward your reply, Thank you and best regards.

And my instance error looks like this . [cid:e8770762-d2b2-4630-9ce6-4d357dc92cee]
