Exclude Disk from Snapshot?

[Kadrim]

Hi there,

is it possible to exclude a Disk from KVM-Snapshot?

The Scenario is like this: i have Server A which has two Disks: Disk 1 (Main/Boot - QCOW2) and Disk 2 ("Data Grave" - RAW).

Currently i cannot take a snapshot at all, because not all Disks are in QCOW2-Format.
So the first question is: can i somehow tell Proxmox or KVM to do the snapshot anyway? Only Disk 1 is important, and Disk 2 should not be included in any Snapshot.

Another way would be, to convert the "Data-Grave" to QCOW2, then the Snapshot option would work, but as the title says: is it possible to not include it? I do not want to "record" all the changes done on Disk 2 at all.

My last resort would be a bit blunt: i could remoe the Raw-Disk completely from the server and offer it via iSCSI. That way, the machine could create a snapshot and the Disk 2 would stay in Raw-Format and not be included.
But that option has a big overhead in comparision to adding the disk directly.

Any thoughts?

Best regards,
David

unfortunately not, i am afraid my outlined scenario via iscsi (or something comparable like nbd) seems to be the only option at the moment

You can live detach disk, that does not support snapshot. Create snapshot. Reattach drive.
