I have a machine with 180 or so logical volumes as well as an OS partition that were wiped out with a format when reinstalling centOS6. I made a terrible mistake, not being familiar with the interface to not notice that it was formatting the entire disk rather then taking me to the partition manager that I've been used to since the redhat days. I cancelled the formatting with a control alt delete as soon as I noticed the issue but my VolGroup00 is gone from view and in it's place is a new volgroup that the installer created.

Is there anything I can do to recover that data?

Obviously. Was looking for something a little more helpful then that. I've found "testdisk". – user165520 Mar 20 '13 at 18:19
Testdisk has been used to restore lost partitions. I've used it once before successfully and I was able to access my data after performing a fsck. – Andrew Ty. Apr 17 '13 at 21:34

Probably too late to help in this case... See my answer to this question on Unix & Linux:
