Special Forums Hardware Filesystems, Disks and Memory Can't repair super block, bad magic number Post 302562541 by dallasw1983 on Friday 7th of October 2011 08:49:56 AM

I ran the three and returned this:
Code:
# pvscan
No matching physical volumes found.
# vgscan
Reading all physical volumes. This may take a while...
# vgdisplay

I came across a program called TestDisk, its used to repair partition tables.
I haven't used it yet since it wants to know which partition table the drive uses and I'm not sure. It looks like it analyzes first, then if it finds any, it can make the repairs.

TestDisk - Official
cgsecurity.org/wiki/TestDisk

TestDisk - In use
geekyprojects.com/storage/how-to-repair-a-damaged-partition-table-or-mbr/

Should I use that since lvm didn't return any thing?
