NFS

NFS maybe by dynamically mounted on demand in the WebUI but affects LXC/VM starts if mapped drives are not mounted.

Automatically mount NFS via FSTAB on boot.

Create NFS mount locations

See NFS for mounting options.

# Set mount immutable to prevent writes when not mounted.
mkdir /d
mkdir {MOUNT}
chattr +i /d
cd /d
chattr +i *  # Changes required unsetting.

/etc/fstab

0644 root:root

{SERVER}:/d/pve /d/pve nfs4 rw,nfsvers=4,minorversion=2,proto=tcp,fsc,rsize=1048576,wsize=1048576,nocto,_netdev 0 0

Map NFS UID/GID for LXC containers

LXC containers using mounted NFS drives must map the LXC UID/GID to PVE UID/GID. Squashed NFS drives must use mapped root user (typically 165536).

If unsure, attempt to read/write from the LXC container and view file permissions on NFS server to see what the actual write permissions are.

systemctl daemon-reload
mount -a
ls -l /d  # Mounted R/W with NFS squashed permissions.

Cluster data storage over NFS. NFS must be mounted on all cluster nodes before adding storage.

pvesm add dir pve --path /d/pve --content images,vztmpl,backup,snippets,rootdir,iso
reboot  # NFS should be mounted on boot.
