Our system experienced a hard reboot, and when it came up, we started getting panics. The boot mount was on an LVM volume. We recovered the GPT partition but all of the LVM commands that I have run have seemed to indicated that no LVM volumes are present. It also looks like LVM partitions should be prefixed with the text-config file (for rescue reasons) but we just have binary data (which makes me nervous).
Is there a more forensic/aggressive recovery method for LVM?
