Step one: Do a full disk backup. Boot to a live-CD, then back everything |
| 13 |
up with dd or -- if available -- ddrescue. |
| 14 |
|
| 15 |
Step two: Replace broken partitions with `mount --bind` versions from |
| 16 |
the live-CD. Then chroot into your system. Refer to the Gentoo Handbook |
| 17 |
for details. |
| 18 |
|
| 19 |
Step three: Do you still have /etc? In that case, you can try to restore |
| 20 |
the LVM metadata from backups that are automatically created by certain |
| 21 |
operations. |
| 22 |
|
| 23 |
Try `vgcfgrestore --list <volume group>` from a to see what is available. |
| 24 |
|
| 25 |
Step four: Post more info. |
