NFS Slow/Stuck Shutdown

[vertigo8]

Hi

I'm having issues with NFS with my shutdown of PVE being stuck, or takes forever/long time Specifically the LXC container, is where the hold up is.

My setup is as follows:

1. Running pve 8.1.4
2. Running pci passthrough with a HBA to a TrueNAS VM.
3. TrueNAS VM hosts my NFS shares.
4. NFS shares are mounted on my PVE host/parent with automount via systemctl.
5. A LXC container has the above NFS shares in above step mounted via a bind from the PVE host

Steps I've done to try to alleviate the issue:

1. Added a hookscript to the LXC, where under the pre-stop section, I have "fusermount -uz /mnt/share" command
2. Added a shutdown service to the PVE host/parent, which stops the automount systemctl service and unmounts on PVE

Any ideas what I could be doing wrong here?

Thanks.
