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?

NAME
repartition - load a partition table SYNOPSIS
repartition device [partition-file] DESCRIPTION
Repartition uploads a new partition table for the partitions of device. The table is obtained from the first sector of partition-file if given, device otherwise. Device may refer to the whole drive or a primary partition, depending on whether you want to upload a partition or a subpartition table. The partitions will be truncated to fit within the enclosing device like the disk driver does, unless the numbers are coming from partition-file. EXAMPLES
repartition /dev/hd0 repartition /dev/hd4 /etc/hd4.table Reload the partition table of drive 0 setting /dev/hd[1-4], and the subpartition table of /dev/hd4 setting /dev/hd4[a-d] using a file. The latter may be useful if you need more than the 4 subpartitions a single Minix partition gives you. DIAGNOSTICS
The new table is printed on standard output. FILES
/dev/hd[0-9] SEE ALSO
hd(4), part(8). BUGS
The disk must be in use for the changes to stick. The partition table of an idle disk will be reloaded on the first open. AUTHOR
