Open Stack

For testing purposes, I created a new volume of size 1 GB and attached it to an instance. I could now see the status “In Use” in the GUI. Also in the VM, I did a sudo fdisk –l to see a new volume mounted on /dev/vdc. I then detached the volume again, the status message was detached but in the volume it displays “In Use”. I am unable to delete the volume now.

Can I know does it usually take longer time to delete? Is there a workaround for this problem?

Can you please run in debug mode and try to trace the log.

I could find traces of INFO about the volume creation in the nova-compute.log, nova-volume.log and nova-api.log but I couldn't find any ERROR.
Using the CLI (nova volume-list), I see the status as "attaching".

ok if you are SURE that there is not a single trace in nova-compute.log; then check nova-api on the controller, you'll see the volume creation request there.
Have you tried with the CLI?
