kernel 5.13.19-1-pve #1 SMP PVE 5.13.19-2

pvesm nfsscan found my nfs export

Try running:
`update-initramfs`
`proxmox-boot-tool refresh`
`update-grub`
and rebooting

Background:
https://lore.kernel.org/all/1637926692.uyvrkty41j.astroid@nora.none/

This is an issue in the kernel config - which has been fixed for newer kernels - and which can be mitigated locally by recreating the initramfs and rebooting

I hope this helps!

Many thanks!

It works

Instructions above from Stoiko helped me today with an error I hadn't seen before.

When I click on `synology-nas-storage` the Summary will show that it allows the following Content: VZDump backup file, Disk image, ISO image, Container, Snippets, Container template. But if I click on its `Backups` tab it says "mount error: mount NFS: No such device (500)"

The Storage can be accessed again with no problems. Thank you!
