Description of problem:
thin_repair isn't able to repair metadata that got full and corrupt. using this bz as per IRC chat with zkabelac for hopefully manual recovery of metadata. gathered dd dump of original metadata.

Version-Release number of selected component (if applicable):
RHEL 7.4


I will attach the compressed dd dump of original metadata and the vgcfgbackup
