Good morning!

First of all, the product looks great! I've been working with VMware, but this is great too.

But.. I've a question. I've installed a HP ML115 G5 for testing purposes at home (study, testing for customers etc). This system has 3 sATA 250 GB harddisks. The system has a raid controller onboard, but Proxmox sees only the separate disks. So I've disabled the controller, only using the separate disks.

So far, so good - Proxmox runs fine (1x Windows 7 for testing, 2x windows 2008).

The problem is: how can I use the other 2 harddisks for virtual machines? While creating a new virtual machine I cannot point to a drive to place it.

I'm new to Linux (yes.. I'm a Windows guy. :rolleyes: ) so... any help would be appriciated!

Regards,

Arie

You have at least three options:

- edit config files in /etc/qemu-server/<VMID>.conf manually, point the disk to a new location, for example:

scsi0: /mnt/new_disk/some_virtual_disk...
virtio0: /mnt/new_disk/other_virtual_disk...

Currently, there is no way to editthis values from the web interface


- mount /var/lib/vz/images/ on a new disk - this means all images will be stored on a new disk (probably a good idea to move the contents of this directory to a new disk)


- use mount -o bind, and either mount /var/lib/vz/images/ or individual virtual machines on a new disk

not supported yet on the web interface but quite easy via command line.

just take a look on a VM config file (VMID is to replaced with your virtual machine number).

Code:
cat /etc/qemu-server/VMID.conf

name: deb501-netinstall-amd64
ide2: debian-501-amd64-netinst.iso,media=cdrom
smp: 1
vlan0: rtl8139=9E:18:24:4D:C8:BF
bootdisk: ide0
ide0: vm-114-disk.qcow2
ostype: l26
memory: 512
currently we use disk image files in qcow2 format as default, see "ide0: vm-114-disk.qcow2"

now, if you want to use a phyical disk partition, just change this line to something like:

Code:
ide0: /dev/sdb1
but take care, you should partition your hard drive first with 'fdisk /dev/sdb'. On Linux systems with sata drives, the first hard drive is normally /dev/sda, the next /dev/sdb, ... And the partitions on these drives are /dev/sda1, /dev/sda2,...

so I assume your Proxmox VE is installed on /dev/sda1 (this is the boot partition) and /dev/sda2 (this is the LVM partition with all the rest).

The upcoming Proxmox VE 2.x will make the use of extra storage (local and remote) easier, see roadmap.
