I run a Proxmox VE Cluster version 7.4.3 and I want to mount a NFS storage.
The NFS server is a ubuntu nfs-kernel-server and I configured it so that it only accepts NFS version 4 mounts.

Unfortunately the proxmox server does not accept version 4 mounts.
This is what log says:

Code: 
pve1 pvestatd[1074]: mount error: mount.nfs: requested NFS version or transport protocol is not supported

Is there a way to mount NFSv4?
 
You can probably start here:
https://forum.proxmox.com/threads/mount-nfs-4-1-share.43034/#post-206656

If that doesnt help, try other results from "proxmox nfsv4" search, or just "nfsv4" in forum. There were some issues with some kernels, if i remember correctly.
It always helps when requester specifies their software versions (pveversion -v) and provides at least some configuration information (cat /etc/pve/storage.cfg).


Blockbridge : Ultra low latency all-NVME shared storage for Proxmox - https://www.blockbridge.com/proxmox
 
The NFSv4 itself server works.
I can mount all exports on other servers, but proxmox complains and states that this version is not supported.
