I did a diff and the contents of the the *Original *meta file (that works
and VM starts but have bad file system) and the *Backup *meta file (the
files being restored from nfs snapshot) *are exactly the same*.
Contents are listed blow. Also the files sizes for all six related files
are exactly the same.

Hi Usman,
can you paste somewhere the content of the meta files?
$ cat 039a8482-c267-4051-b1e6-1c1dee49b3d7.meta
8d48505d-846d-49a7-8b50-d972ee051145.meta
could you also provide the absolute path to those files? (in the vdsm host)
Thanks,
