Title:
encrypted iSCSI volume fails to attach, name too long
Status in OpenStack Compute (nova):
Won't Fix
Status in os-brick:
New
Bug description:
When running the following tempest tests an error occurs in n-cpu:
tempest.scenario.test_encrypted_cinder_volumes.TestEncryptedCinderVolumes.test_encrypted_cinder_volumes_cryptsetup
test_encrypted_cinder_volumes_luks
This occurred when using devstack with nova at:
HEAD is now at d0c2684 Merge "libvirt: Resize down an instance booted
from a volume"
Both stack traces below are from n-cpu logs:

To reproduce, run the tempest tests mentioned above on system that has an ip,
iscsi properties and volume name which, when combined, results in a very long
name used by cryptsetup. The long name will cause the above error to occur.
