Recovery of RAID and LVM2 Volumes

 Raid and Logical Volume Managers are great, until you lose data.

The combination of Linux software RAID (Redundant Array of Inexpensive Disks) and LVM2 (Logical Volume Manager, version 2) offered in modern Linux operating systems offers both robustness and flexibility, but at the cost of complexity should you ever need to recover data from a drive formatted with software RAID and LVM2 partitions. I found this out the hard way when I recently tried to mount a system disk created with RAID and LVM2 on a different computer. The first attempts to read the filesystems on the disk failed in a frustrating manner.

LVM recovery tale

 Over the weekend I had the worrying experience of losing my LVM settings and potentially all my data… a quick search on the web showed a confusing set of information, much of it for older versions of LVM and therefore rather suspect.

Well, I recovered all my data and it was really quite simple, so I’ve written up what I did in the hope that someone else, in a similar situation, will find it useful. It’s a scary thing, losing the whole hard disk and knowing that, in reality, its all there.
