Hi,
Here is my System Setup

Pentium III 900 MHZ
512 MB Ram
HDD1: 160GB
HDD2: 10GB
HDD3: 80GB

Partitions:
HDD1: 150GB /srv ext3 10GB Swap
HDD2: 10GB / ext3
HDD3: 80 GB /mount xfs

I've got all vServers Running in the 150Gig Partition.
I want to add the 80Gig Drive too an VPS 250 which shall be an fileserver containing samba etc.
The Problem is, how do i add it?

Thanks for your help.

Chris

Hi Chris,

please, correct me if i understood your idea wrong: you want to add an additional drive and create a Container that will reside on this drive, right?

If yes, then just mount additional drive to some directory on the Hardware Node, for example /mnt/driveX, then create a Container using additional options to vzctl: "--private" and "--root".
Check "man vzctl" for details.

Hope this helps.

Ok,
maybe I stated my Problem not good enough.

I don't want to create an VPS on an harddisk,
i wan't to add an Harddisk Partition to an existing Virtual Enviroment.

Example:

VPS 250: Fileserver

/boot
...
/home
/home/iso ==> Partition 2 HDD 3
/home/audio ==> Partition 3 HDD 3
.....

This is what I would need.
The Harddisk was part of an older Server.
I thought of just putting an VE on the HDD, but theres not enough place left and i don't want to delete anything on the harddisk.

Well,

the simplest way is to mount that disk on Hardware node to a directory (e.g. /data/tmp) and then bindmount /mnt to the Container.
You can automate this by per-container "mount" script:

# cat /etc/vz/conf/101.mount
#!/bin/bash

. /etc/vz/vz.conf

mount -n -o bind /data/tmp $VE_ROOT/data/tmp

You can also read about --devices / --devnodes vzctl options, they allow you to get access to /dev/XXX device from inside a Container, and then just mount the device inside a Container as usual. But in this case please, first play with ext3 partitions, for xfs partition you might face some additional issues.

I already tried to play arround with the

--devices / --devnodes

options, but the problem I encoutered was, that due to a lack, that the modul directory of the kernel wasn't available in side each VPS, he couldn't handle the XFS filesystem.

To Copy the Content from one disk to another is quite a little bit nasty.
Its almost 80 Gigs and takes a while (IDE)

Well gona try the other solution sone

I've just added a new disk and wanted to make it available to a container to use as additional storage. This worked for me on ext3.

vzctl set 1000 --devnodes sdb1:rw -save
