Hi all

been using PVE for a while now, but only lately started to get an issue with NFS shares or I think it is NFS shares causing the problem.

conf file of LXC

arch: amd64
cores: 4
features: mount=nfs;cifs,nesting=1
hostname: Tautulli
memory: 6144
nameserver: 10.0.0.200
net0: name=eth0,bridge=vmbr0,firewall=1,gw=10.0.0.2,hwaddr=BC:24:11:79:D2:7A,ip=10.0.0.123/24,type=veth
onboot: 0
ostype: ubuntu
rootfs: Fastboi:203/vm-203-disk-0.raw,size=40G
startup: order=6,up=5
swap: 6144


using fstab to mount 3 nfs mount points hosted on a OMV instance VM, which has a passthrough for a Sata card and a Dell perc controller.

now I can't 100% pinpoint the problem but when I want to reboot a LXC which has a NFS mount point it just hangs and never stops,reboots or force via cli. I have not found when the exact trigger is, sometimes it takes 2 days other times I've been running for over a month without issues.

in the end, I have to do a foul method of finding the pid killing it then rebooting the PVE host and then only will the lxc come back online again.

am I being very dumb with the method I'm doing the mount points ?

anything else I can provide that might lead to finding the issue?
