Bug Description
SUSE Linux / Icehouse / CINDER /LVM TGT iSCSI
I am trying to dettach volume using Icehouse version. The backend model is LVM, tgt and iSCSI.
However, after a long while, the volume keeps in "dettaching" status.
Then I open cinder-volume.log, find exceptions as bellows:
2014-06-20 14:38:22.438 28194 DEBUG cinder.
2014-06-20 14:38:22.531 28194 DEBUG cinder.

Seems like the problem appears because execute the cmd : sudo cinder-rootwrap /etc/cinder/
and using cmd tgt-admin -s shows:

and links from compute node still exist and using iscsiadm -m node -T iqn.2010-
I am wondering why the problem appears all the time, can anybody help me. Many thanks
