Doc Text:
.RBD images can now be removed even if the optional journal is missing or corrupt If the RBD journaling feature is enabled, a missing journal prevents the image from being opened in an attempt to prevent possible data corruption. This safety feature also prevented an image from being removed if its journal was unavailable. Previously, the journaling feature had to be disabled before attempting to remove the image if this situation occurred. With this update, RBD image removal skips any attempt to open the journal because its integrity is not important when the image is being deleted. As a result, RBD images can now be removed even if the optional journal is missing or corrupt.
