[linux-lvm] undelete logical volume

[Andreas Unterkircher]

Hi,

I made a big mistake and deleted a logical volume with some still needed data.

It was the only active lv and no other write access happened on the physical 
disks till yet. Also I have no backup of lvm's metadata.

Is there any way to recover the lost logical volume? (lvm2)

Use RIP (R)ecovery (I)s (P)ossible! (v15.2)  to boot up.
And use command hexdump /dev/hda1 to collect the old LVM config information.
They are nearly 1200.
Use the information to create a metadata file.
Use cfgrestore to recover.
Then mount back the lost LogVol00.

Just my two cents.

Thx for the hint. Also I found out that a metadata backup is created on
a every command in /etc/lvm/archives.
The lv has been recovered, but it looks like the first xxx bytes of the
lv have changed. Luks doesn't accept it
as luks partition anymore and so I can't mount the encrypted partition
anymore. Data lost.... Backup is always
a good idea...
