Recover an ext4 file system on an lvm logical volume

#1 Post by jgdempsey » 21 Jun 2017, 01:08

Hi all,
I have been able to recover all of the Logic Volume info for a LVM drive, but am getting a "Bad magic number" error for all of the Superblocks that I have tried when I try to do an e2fsck on the volume, which had an ext4 file system on it. I have tried a number of the alternative super blocks, but so far get the same error.
Any other possibilities for recovery?
Thanks
JD

Please post the output of pvdisplay -a, vgdisplay, lvdisplay -a
Run TestDisk, Advanced, SuperBlock on the ext4 filesystem, post the testdisk.log file content and the e2fsck command you are using
