[Bug 1036093] [NEW] nova volume-attach with high device name keeps volume in state "attaching"

[Kurt Huwig]

Public bug reported:

If I attach a volume to a high device name, e.g. /dev/vdm

nova volume-attach f91e2097-5e2f-47df-90ea-f6da292df41b 4072 /dev/vdm

then nothing happens within the instance and the volume is in the state
"attaching". According to the logs the iscsi attach works and the lv is
in use by tgt. After that, I am unable to detach the volume or shutdown
the instance. The first device that causes the problem is /dev/vdk which
means the first 10 letters a-j are working fine.
