[SOLVED] PBS datastore on NFS

Jul 20, 2022
I have PBS 2.2-7 running as a VM on Proxmox 7.2-14. I have a datastore on PBS that I wish to put on an NFS server VM so that I can share it with Duplicati, which is running in yet another VM. I will use Duplicati to encrypt and store the PBS datastore on a cloud storage service.

My question has to do with accessing a datastore via NFS.

I have used Proxmox to move the datastore disk from PBS to the NFS server. On the NFS server, I have exported the datastore to make it accessible to the PBS VM. This was successful as I am able to mount and browse the NFS-mounted datastore from the PBS console.

Now I want to access this NFS mount as an existing datastore in PBS.

When I do this, PBS creates an empty datastore in /mnt/datastore/NFS2.

If I mount the real (NFS) datastore at /mnt/datastore/NFS2, then PBS will not allow me to add the datastore, because one already exists at that location.

So how do I go about putting this NFS-mounted datastore back into PBS?

You could try to edit the "path" in the /etc/proxmox-backup/datastrore.cfg form the old datastore location to the mountpoint of the new NFS share.
