NFS nightmare

[Saint Michael]

I need to mount an NFS share inside a privileged LXC container, but it fails. I am not using AppArmor, for I disabled it on /proc/cmdline (apparmor=0).  So what is keeping me from mounting the NFS share? I get this error: "mount: /remote: bad option; for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount.<type> helper program."
The command is :
mkdir -p /remote;mount -t nfs 208.73.236.249:/master /remote

my config file has:

lxc.mount.auto=
lxc.mount.auto=proc:rw sys:rw cgroup:rw
lxc.apparmor.profile=unconfined
lxc.tty.max = 10
lxc.pty.max = 1024
lxc.cgroup2.devices.allow = c 1:3 rwm
lxc.cgroup2.devices.allow = c 1:5 rwm
lxc.cgroup2.devices.allow = c 5:1 rwm
lxc.cgroup2.devices.allow = c 5:0 rwm
lxc.cgroup2.devices.allow = c 4:0 rwm
lxc.cgroup2.devices.allow = c 4:1 rwm
lxc.cgroup2.devices.allow = c 1:9 rwm
lxc.cgroup2.devices.allow = c 1:8 rwm
lxc.cgroup2.devices.allow = c 136:* rwm
lxc.cgroup2.devices.allow = c 5:2 rwm
lxc.cgroup2.devices.allow = c 254:0 rwm
lxc.cgroup2.devices.allow = c 10:137 rwm # loop-control
lxc.cgroup2.devices.allow = b 7:* rwm    # loop*
lxc.cgroup2.devices.allow = c 10:229 rwm #fuse
lxc.cgroup2.devices.allow = c 10:200 rwm #docker
lxc.cgroup2.devices.allow= a
lxc.cap.drop=
lxc.cgroup2.devices.deny=
lxc.autodev= 1
lxc.hook.autodev = sh -c 'mknod ${LXC_ROOTFS_MOUNT}/dev/fuse c 10 229'

Do I need to add something to the config file?

Hi,

it says it needs a helper program.

mount: /remote: bad option; for several filesystems (e.g. nfs,
cifs) you might need a /sbin/mount.<type> helper program

ls -l /sbin/mount.nfs*

What give you this command? The error message looks like missing a package.

Cheers,

We are using NFS shares, make sure that you have the kernel modules loaded:

CONFIG_PACKAGE_kmod-fs-nfs=y

CONFIG_PACKAGE_kmod-fs-nfs-common=y

CONFIG_PACKAGE_nfs-utils=y

(might be different for your host).

Best, Todor

I solved it. It needed the package nfs-common.

many thanks to all.
