export vm problem, disk not available when vm offline

[Dale.Sykora]

I have a vm on a proxmox 7.4 cluster with disks under LVM, and I want to export as a qcow2.
I found the disk path with

root@n2:~# pvesm path vd2v1:vm-118-disk-0
/dev/msa2040-vd2v1/vm-118-disk-0

However, the path in unavailable when the VM is turned off (details below).

How do I make the disk paths "available" so I can use qemu-img to export with command below?

qemu-img convert -O qcow2 -f raw /dev/msa2040-vd2v1/vm-118-disk-0 /mnt/pve/backup2/images/clone-vm118-disk0.qcow2

I could try lvchange -a to activate the LV, but not sure if that will break anything on a production cluster... Please advise?

here is what lvs shows when vm is off

root@n2:~# lvs | grep 118
vm-118-disk-0 msa2040-vd2v1 -wi------- 100.00g
vm-118-disk-1 msa2040-vd2v1 -wi------- 300.00g

lvdisplay show status NOT available

You should be ok activating the LV manually, as long as you are sure that no one is using it.
You can also use "qm disk move" command. With appropriate arguments it should convert your raw disk to qcow on target storage.

Good luck
