Start LXC container (or VM) after an NFS share is available

[Angelone]

Hi all,

I've spinned a VM to run TrueNas on proxmox 7.4-16 and it expose an NFS share that has been mounted in the Proxmox host:

/etc/pve/storage.cfg

nfs: nfsdata
        export /mnt/hddstorage/nfsdata
        path /mnt/pve/nfsdata
        server <TrueNAS_VM_IP>
        content images
        prune-backups keep-all=1

I've also an LXC container that uses the share and naturally it will fail to boot if the NFS share is not available. Is there a way to boot the LXC container only when the NFS has been fully mounted on the host?
I know that I can add a boot delay of "random" time but I'm looking for a more reliable solution.

Many thanks

Currently, I'm having the same issue. I mounted via /etc/fstab, but that should not make a difference. Did you find a solution?

I now have this setup in testing and am looking into options...did you find a solution? I'm assuming the lxc needs to not start automatically and a script needs to run on boot up to check for nfs share connectivity before starting the lxc through the cli? I will be trying to get something together on this over the next couple of days but if there's a solution out there already???

I've setup the mounts on the proxmox host using autofs and configured the vm to have order=1 and startup delay=120, the lxc is then set to order=2

This set me right, there's another option too via systemd.automount which I've not tried as yet: https://forum.proxmox.com/threads/truenas-vm-autofs-mount-dependent-lxcs.155261/
