Title:
'in use' error when Nova volume encryptors format cinder volumes
Status in OpenStack Compute (nova):
Fix Released
Bug description:
Tempest scenario TestEncryptedCinderVolumes has been silently skipped when
run with NetApp iSCSI cinder volume drivers because they did not set the
'encrypted' key in the connection_info['data'] dict in their
initialize_connection methods. Change
https://review.openstack.org/#/c/193673/ - which sets the encrypted flag
generically, in the VolumeManager's initialize_connection, on the basis of the
volume.encryption_key_id value - causes this test to actually run its
encryption providers and exposes a problem in LuksEncryptor:_format_volume()
for these iSCSI volumes.
In TestEncryptedCinderVolumes we get the following exception:
