Hi all,

I want to create a backup of our a VM on a existing Thinpool. As it is only a temporary backup before an upgrade of the VM (and we have an external backup job as well) it is okay when the backup is on the same machine as the VM itself (as I don't know where Proxmox is storing snapshots I don't trust them this much (as the snapshot disk is only created when snapshot of memory is activated)).

As the storage on the host itself is not enough, I need to add the storage to our existing LVM-Thin: Is there a recommend way to create a LVM-Disk and mount it as directory?

Regards
SunBlack

Assuming your thinpool is pve/data (default in Proxmox VE) and you want to create a 10GB volume for backups named "backupvolume" run
Code:
lvcreate -V10G -T pve/data -n backupvolume

and create afterwards a filesystem in it and mount it.

Note that 10G is just the virtual size. Be careful to avoid overprovisioning.
