Move VMs from old disk.

[diager0357]

Hello
I installed new server of Proxmox. I would like to move my VMs from disk of my old server.
Unfortunatelly, I don't know how to ucomplish.
I have disks like this:


root@local:/mnt/bak# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda ├─sda1 8:1 0 1007K 0 part ├─sda2 8:2 0 512M 0 part └─sda3 sdb ├─sdb1 8:17 0 1007K 0 part ├─sdb2 8:18 0 512M 0 part /boot/efi └─sdb3 ├─pve-swap 253:0 0 8G 0 lvm [SWAP] ├─pve-root 253:1 0 ├─pve-data_tmeta 253:2 0 3.5G 0 lvm 338.4G 0 lvm └─pve-data_tdata 253 └─pve-data 253:4 0 338.4G 0 lvm sr0 11:0 1 1024M 0 rom


My old disk is sda. And when I am trying to mount it on my system I am receiving:


root@local:/mnt/bak1# mount /dev/sda3 /mnt/bak2 mount: /mnt/bak2: unknown filesystem type 'LVM2_member'.


Can someone help my how to mount my old data on new server of Proxmox?

Thanks in advance.

Hey,

All is in the return of your "problem" ^^

First of all, this is not a Proxmox "problem". It's a storage missendestanding.

On your old installation, you've installed it in "LVM configuration".

LVM => Logical Volume Manager.

You cannot mount a disk LVM used directly. You need to mount theses logical volumes.

Check theses commands in CLI:
logical volume scan short: lvs
logical volume scan "extended": lvdisplay

Logical group scan short: vgs
Logical group scan extended: vgdisplay

Physical volume scan short: pvs
Physical volume scan extended: pvdisplay.

You can found theses logicals volumes links in /dev/mapper/idk-actually

Your mount command seem to be like that:
mount /dev/mapper/VG_name/lv_name /your/mountpoint

(ps: i don't really remember the syntaxe in the folder /dev/mapper/, it could be like VG_NAME-LV_name )

Bests rresgards
