NFS TimeOut

Hello,

I have a problem with backing up my VM's, I have a PiNAS (OpenMediaVault5.x) setup in which I mount an NFS share to Proxmox and use that to store backups of the VM's (so they are on separate hardware).

Recently this has stopped working, but not completely. If I start to perform a backup it starts but after a few second it hangs and finally locks up Proxmox so I have to reboot. I believe it is waiting; I have also found a lot of errors in the Syslog (whether the backup is running or not) "Apr 05 19:57:28 pve pvestatd[2800]: storage 'Packup_Server' is not online". The strange thing is I can still access the share from my PC (Windows 10) or Proxmox itself.

I checked the ports are ok:
root@pve:~# nmap 10.1.30.201
Starting Nmap 7.70 ( https://nmap.org ) at 2021-04-05 19:37 BST
Nmap scan report for 10.1.30.201
Host is up (0.00092s latency).
Not shown: 992 closed ports
PORT STATE SERVICE
22/tcp open ssh

111/tcp open rpcbind
139/tcp open netbios-ssn
445/tcp open microsoft-ds
2049/tcp open nfs
5357/tcp open wsdapi

I checked rpcinfo:
root@pve:~# rpcinfo -p
program vers proto port service

100000 3 tcp 111 portmapper
100000 2 tcp 111 portmapper

100021 1 tcp 35017 nlockmgr
100021 3 tcp 35017 nlockmgr
100021 4 tcp 35017 nlockmgr

I checked the mounts and they work:
root@pve:~# showmount -e 10.1.30.201
Export list for 10.1.30.201:
/export 10.1.0.0/16
/export/Backup 10.1.0.0/16

root@pve:~# pvesm nfsscan 10.1.30.201
/export 10.1.0.0/16
/export/Backup 10.1.0.0/16

I even checked I could see old backups and they work:
pvesm list Packup_Server
Volid Format Type Size VMID
Packup_Server:101/vm-101-disk-0.raw raw images 34359738368 101

(There are lots more I have only grabbed the top few, as you can see I have not had any sucessful backups in a while :s )

But even while writing this I still get this error:
Apr 05 20:04:29 pve pvestatd[2800]: storage 'Packup_Server' is not online

If I attempt a backup it locks up the whole of Proxmox which then requires a restart.

The config for the mount it:

I have checked my firewall and I find nothing in the logs, I have also create a dedicated any/any rule for the two to speak:
Proxmox VLAN rule
1617650092101.png
PINas VLAN rule:
1617650125032.png

I am really lost about where to go next, can anyone help?

Many thanks
