Title:
  Attaching LVM encrypted volumes (with LUKS) could cause data loss if
  LUKS headers get corrupted

Status in Cinder:
  New
Status in OpenStack Compute (Nova):
  Invalid
Status in OpenStack Security Advisories:
  Won't Fix

Bug description:
  I have doubts about the flow of the volume attaching operation, as
  defined in /usr/lib/python2.6/site-
  packages/nova/volume/encryptors/luks.py.

  If the device is not recognized to be a valid luks device, the script is luks formatting it! So if for some reason the luks header get corrupted, it erases the whole data.
  To manage corrupted headers there are the 

      cryptsetup luksHeaderBackup

  and

      cryptsetup luksHeaderRestore

  commands that respectively do the backup and the restore of the
  headers.

  I think that the process has to be reviewed, and the luksFormat
  operation has to be performed during the volume creation.
