<div><br></div><div>I put the old HDD containing data I would like to recover in another machine and tried to see what I could do. pvscan and lvscan would show a pv, but would report the Incorrect metadata area header checksum warning. I tried to mount my /boot partition, but it said something along the lines of "Unknown filesystem type LVM.....". However, if I used *-t ext2*, the /boot partition would mount without a problem. I ran fsck.ext4 (big mistake) on the /boot partition which destroyed all of the data on that partition. The destruction of /boot is not important to me, but the steps I took to do it may give some insight on my LVM issue.</div>
<div><br></div><div>At this point, I believe that I accidentally told sfdisk that my /boot was an LVM partition which was why I was unable to boot into my os.</div><div><br></div><div><br></div><div>
Now I have the HDD set up and when running pvdisplay I see the HDD, but it does not show a VG name and reports it as a "new physical volume". Because it's not assigned to a VG, it does not get placed in /dev/mapper, which means I cannot run cryptsetup to unlock the drive.</div>
<div><br></div><div>Any recovery/backup information that I see being used by other people to rectify similar situations resided on the drive I am having problems with, which makes it impossible for me to use such data for recovery.</div>
<div><br></div><div>I am hoping there is a way to assign this PV to a VG without destroying any data on the disk so that I can decrypt it and export the data from the drive.</div><div><br></div><div>
I am currently dd'ing the drive to another drive so that any suggestions I get from this mailing list can be executed without taking me further from retrieving my data.</div><div><br></div><div>I appreciate you taking the time to read this email and thank you for any input or suggestions you may have.</div>
