Having trouble with bind mount

[gob]

[SOLVED]

Hi
I have a new PVE 3.1 server.
I have a second RAID array with an LVM volume mounted in fstab as /FP02storage

That is fine and I can use that volume.
I am trying to bind mount it into VM 100 as /FP02storage

There is a 100.mount file with the following script:

#!/bin/bash
. /etc/vz/vz.conf
. ${VE_CONFFILE}
SRC1=/FP02storage
DST1=/FP02storage


mount -n -t simfs ${SRC1} ${VE_ROOT}${DST1} -o ${SRC1}

however when I attempt to start VM 100 it won't start and the following task status is posted:

Starting container ...
mount: mount point /var/lib/vz/root/100/FP02storage does not exist
Error executing mount script /etc/pve/openvz/100.mount
TASK ERROR: command 'vzctl start 100' failed: exit code 79

I tried creating the mount point inside /var/lib/vz/root/100/ also, but that didn't work either.

Where am I going wrong?

Cheers.

Fixed this!

I had to run:

mkdir /FP02storage

from within vm 100 before attempting to mount it.

Why do you mount using simfs?
and why do you not want it written to mtab?
And lastly, what you do is not a bind mount!!

What you should do instead:
mount --bind ${SRC1} ${VE_ROOT}${DST1}

And to avoid your problem in the future:
mkdir -p ${VE_ROOT}${DST1} && mount --bind ${SRC1} ${VE_ROOT}${DST1}

thanks for your reply mir.

To be honest, that was the last script I tried from various posted examples. All of the previous scripts did use --bind and I hadn't even noticed it was --simfs.
I have no idea what difference that option makes nor whether or not I need it written to mtab ;-)
I will switch it to bind when I am next able to down the server.

Thanks also for the mkdir tip. I will put that in also..
