Dear Proxmox-Experts,

i tried to create a Directory in Proxmox. But the dialog tells me "No Disks unused":

When i look at the "Disks" on the Node, almos all partitions are not mounted:

Is that a normal behaviour?

I hope someone can help me. Unfortuantely, i´m not an expert in Proxmox.

Greetings!
 
Hi,

this is normal & expected. You have a single disk in your system, which is already used as the boot disk by Proxmox VE.
As for the partitions, expected as well - the first too are boot partitions and the third is the actual root partition of the system.

As to why it says that the root partition (so /dev/nvme0n1p3) is not mounted - that is simply due to how LVM storage works underneath.

If you want to actually add another storage (so e.g. a directory storage), you need a free (thus second) disk in the system.

As you seem to have choosen either ext4 or XFS during installation, you have a local and local-lvm storage defined for your guests.
I'd suggest reading a bit into the Storage chapter of our admin guide, hopefully that should clear things up a bit regarding storage in Proxmox VE. :)

Is this stating that proxmox can not run on a single disk?

Not at all. The OP has both a directory storage (local) & an lvm-thin (local-lvm) on that single disk (LVM). These storages can be used appropriately for their respective storage types. The OP wasn't able to create a new directory storage, that is all.

I just installed Proxmox for the first time like OP, and ran into the same issue with "No Disks unused". All the space is taken up by the LV. The LVM-Thin has a data dir with 300+GB free. However I can't seem to use any of it.
