LVM bzw. LVM-thin reparieren nach versuchter Diskerweiterung

[stkw]

Ich habe heute versucht mein LVM Laufwerk zu erweitern mit zwei noch verfügbaren Laufwerken.
Dazu habe ich die Anleitung unter folgendem Link verwendet: https://serverfault.com/questions/423544/how-would-i-add-a-second-physical-hard-drive-to-proxmox

Leider ist nun das passiert was bei einem der Kommentare auch dabei steht: Bad magic number in super-block while trying to open /dev/mapper/pve-data

Die Frage ist nun wie kann ich mein Laufwerk wieder reparieren?

root@pve2:~# fsck -nv /dev/mapper/pve-data
fsck from util-linux 2.36.1
e2fsck 1.46.2 (28-Feb-2021)
ext2fs_open2: Bad magic number in super-block
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/mapper/pve-data

The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem.  If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>
 or
    e2fsck -b 32768 <device>
