How does "pvesm alloc" work?

[emdebbed]

I'd like to use `pvesm alloc` but not matter what kind of filename I use is always returns the same error:

root@host:~# pvesm alloc hdd_raid10_data01 100 foo 100G
unable to parse volume filename 'foo'

How is this tool supposed to work?

The disk naming is fixed to specific structure: vm-[VMID]-disk-[DISKID]

Thanks for the response. However after having a look at disks created via the Webinterface I realised that with my storage type "btrfs" the filename must have a fileending like .qcow2

See https://pve.proxmox.com/pve-docs/pvesm.1.html for available file types.

So in the end this worked:

root@host:~# pvesm alloc hdd_raid10_data01 100 bla.qcow2 100G
