[SOLVED] Restore VMs and CTs without the original Drive

[tadopai]

Hello,

my main Hard Disk Drive has gone and all of my CTs / VMs on it. But I have several backups on my Proxmox Backup Server, but can't restore it because my main drive is broken. And if I try it it will delete the vm / ct after the error.


/etc/pve/storage.conf (Server-HDD-400GB is broken and ServerHDD-1TB_1/2 are my new drives)

My Drive Error:

Incorrect checksum in metadata area header on /dev/sdc at 4096
Failed to read mda header from /dev/sdc
Failed to scan VG from /dev/sdc

My fsck.ext4:

root@pve:~# fsck.ext4 -nf /dev/sdb
e2fsck 1.44.5 (15-Dec-2018)
Warning! /dev/sdb is in use.
ext2fs_open2: Bad magic number in super-block
fsck.ext4: Superblock invalid, trying backup blocks...
fsck.ext4: Bad magic number in super-block while trying to open /dev/sdb

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>

Thanks ins advance!

Okay I found a solution.

I format my drive and afterward I named the formatted drive again "Server-HDD-400GB". Now I can restore my backups.
