Proxmox CIFS

proxmox Sep 29, 2020

Adding a Windows Share to Proxmox isnt always straight forward.

First I would attempt to add it using the WebGUI

Enter the ID - Name the Share

Server - Recommend to use IP unless you have an extremely stable DNS

Username - Windows user that has access to the share

Password - as above

Share - This should be automatically populated, select your CIFS share

Domain - enter domain

Content - I select all of them.


What happens if the above doesnt work?

Sometimes you will see an error similar to the below. This generally means the SMB version isnt supported.

mount error(95): Operation not supportedcreate storage failed: error during cfs-locked 'file-storage_cfg' operation: mount error: Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

We can overcome this by using the CLI

Putty onto the Proxmox Node

Enter the following command,

pvesm add cifs ProxBackup --server IP ADDRESS --share ProxmoxBackup --username WINUSER --password WINPASS --domain DOMAIN--smbversion 2.0

smbversion can either be 2.0, 2.1 or 3.0. Try them all until one works.
