Restore VMs after Proxmox system disk died

root@server7:~# pvesm import lvm04:vm-7041-disk-0 raw+size
400 not enough arguments
pvesm import <volume> <format> <filename> [OPTIONS]

Thanks for your time...

pvesm import lvm04:vm-7041-disk-0 raw+size - -with-snapshots 0

zuliasro · Mar 19, 2021

root@server7:~# pvesm import lvm04:vm-7041-disk-0 raw+size - -with-snapshots 0
volume fourth/vm-7041-disk-0 already exists

Looks like pvesm know about the disk only the Proxmox don't.

qm rescan --vmid 7041

Well that means that it's fine, whats the output of:
pvesm list lvm04

check if this file exists and if it contains the storage: /etc/pve/nodes/server7/qemu-server/7041.conf
it should be identical with /etc/pve/qemu-server/7041.conf

if it's not, then:
cp /etc/pve/qemu-server/7041.conf /etc/pve/nodes/server7/qemu-server/7041.conf

And again:
qm rescan --vmid 7041

Ramalama · Mar 20, 2021

and the output of pvesm status ?

Means this VM's should work then:

Code:

vm-7041-disk-0 fourth Vwi-a-tz-- 100.00g fourth 29.98 vm-7100-disk-0 fourth Vwi-a-tz-- 120.00g fourth 2.92 vm-7142-disk-0 fourth Vwi-a-tz-- 40.00g fourth 45.10 vm-7143-disk-0 fourth Vwi-a-tz-- 40.00g fourth 48.23 vm-7144-disk-0 fourth Vwi-a-tz-- 40.00g fourth 43.10

7041, 7100, 7142, 7143, 7144

They should have (example):
/etc/pve/qemu-server/7041.conf
virtio0: lvm04:vm-7041-disk-0,cache=writeback,discard=on,size=100G

Correct?

Then you didn't made the vmconfig?

zuliasro · Mar 20, 2021

No, while I'm not able to attach the disk.

Attach any disk, then detach it, then change the line in the configs:
/etc/pve/qemu-server/7041.conf / /etc/pve/nodes/server7/qemu-server/7041.conf
virtio0: lvm04:vm-7041-disk-0,cache=writeback,discard=on,size=100G

then do a
qm rescan --vmid 7041

Ramalama · Mar 20, 2021

But use another vm storage, not the same (not lvm04), when you create your vm with 7041 as id.

zuliasro · Mar 20, 2021

root@server7:~# qm rescan --vmid 7041
rescan volumes...

Don't booting.

zuliasro · Mar 20, 2021

The disk is disappeared!
