NFS mount Frustration (500 not online)

[fortechitsolutions]

Hi, I have a 'fun' question.

I am trying to mount NFS export to a proxmox host. They are both in 'public' (OVH) hosting so I've setup firewall rules on the NFS server to restrict access to NFS server suitably / allow access only to this client /and restrict ports used to simplify firewall rules.

I can manually mount the NFS export on proxmox command line, thus:

(note IP addresses are fuddled to make less obvious my real public IPs involved)

root@proxmox:/etc/pve# mount  158.99.209.99:/export  /mnt/pve/nfs-tank2

root@proxmox:/etc/pve# df -h

and also

root@proxmox:/mnt/pve/nfs-tank2# mount
sysfs on /sys type sysfs (rw,relatime)
....
158.99.209.99:/export on /mnt/pve/nfs-tank2 type nfs4 (rw,relatime,vers=4.2,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=199.99.99.99,local_lock=none,addr=158.99.209.99)

I can then manually setup a proxmox 'directory' type storage and use this and it works fine. But this is horribly kludge klunky.

If I try to add it via the Storage>Add>NFS GUI then I proceed, I tell it advance > NFS version 4.2 > and specify all things correctly. And it gives me error, storage is not online (500)

In my CLI I can confirm that things look OK also thus:

I am just wondering if this sounds familiar in any way to anyone.

it is driving me up the wall.

Thanks!

Our code uses "showmount" to check if the server is online. So what is the output of

# /sbin/showmount --exports <server>

Hi, thanks for the reply.

Here is output:

root@proxmox:~# /sbin/showmount --exports 158.99.209.99
