[SOLVED] mount.nfs: Protocol not supported

[Andrey G]

Hello.
I try to connect my NAS folder to Proxmox as NFS share.
NAS: Thecus N2310. It supports sharing folder via NFS. It is configured via web, but command line (linux) is also available. (IP 192.168.10.3)
Proxmox:

When I try to add nas storage via web gui I receive mount error: mount.nfs: Protocol not supported (500).
When I try manually mount nfs, I get the same:

But from Ubuntu host I mount this share successfully.
What I do wrong with Proxmox?

You are mounting as nfsv3. Check nfs server versions support on Thecus.

It supports both 3 and 4. See rpcinfo spoiler.

Found in /var/log/syslog
nfsv4: disagrees about version of symbol module_layout
same for nfsv3
any ideas?

Hi

this is typically a outdated kernel .... message loading nfs ...

strange i bet your modinfo would issue a error ...

so to find out the module complaining "disagrees about version of symbol module_layout" ... by dmesg

perhaps a "apt-get update && apt-get dist-upgrade " will solve your problem ....

 

[Andrey G]

Reboot fixed the issue.

Hi Andrey,

Thanks for the info. It solved my problem.
