Can't attach a RBD volume to an instance

 

Hi everyone,

I setup a ceph cluster and I use the RBD driver for nova-volume.
I can create volumes and snapshots but currently I can't attach them to an
instance.
Apparently the volume is detected as busy but it's not, no matter which
name I choose.
I tried from horizon and the command line, same issue.

$ nova --debug volume-attach de3743be-69be-4ec3-8de3-fc7df6903a97 12
