Volume stuck in "in-use" status and can't be detached

[Jo]

When a volume is attached to an instance and the instance is rebooted or crashed the volume gets stuck in "in-use" status. And it can't be detached or re-attached.

It has problems reattaching it is because it is already logged in

so if you check compute log you will see a line like the following:

sudo iscsiadm -m node -T iqn.2010-10.org.openstack:vol-xxxx -p xx.xx.x.xx:xxxx --login
and it will say ProcessExecutionError already exists

The manual workaround is

sudo iscsiadm -m node -T iqn.2010-10.org.openstack:vol-xxxx -p xx.xx.x.xx:xxxx --logout (from the compute-host)

the login will work the next time

Looks like a duplicate of bug 747922 -- could you please test a recent version and confirm that the bug is gone ?

Yes, this is verified and it works fine now.
