Physical Harddisc to Guest System

[KaG]

Hello,

I have the idea to move a File-Server to Proxmox. The Situation is, that i have more than 500GB Files on the File Server. In my point of view proxmox build always a virtual HD for Guest Systems (The Guest System is a Win 2003 or Samba Server).

Problem: In this Situation i have a virtual HD with more than 500GB and it´s not posible to backup and restore this file. and when the VHD is corrupt, nobody can restore documents or something else.

Question: Is it posible to connect a physical HD to proxmox? Maybe with NTFS or FAT or ext3? And is it posible to have this HD in a Raid 1?

I hope you know what i mean and this question is not posted

Yes, you can do that on the command line. Lets say you have an unused disk '/dev/sdc'. First, you need to partition that drive:

# fdisk /dev/sdc

assuming you create a partition called /dev/sdc1. Then create a standard KVM VM - lets assume VMID 777. Then you can use
that device inside your VM with:

# qm set 777 -ide0 /dev/sdc1

The remove the old virtual disk on the web interface.

And is it posible to have this HD in a Raid 1?

It is recommended to use a hardware raid controller.

Hello Dietmar,

thank you for the quick and excelent answer. For me that i am realy sure: That means i can take the HD or one of the Raid 1 HD out of the Proxmox System and but it in in a nother system and can read the date?

I don't understand that question?

I don't understand that question?

The Proxmox Server goes down (CPU fail). I need - for example - a lot of Contracts they saved on the "physical" HD at the Guest System win 2003 Server at proxmox. Today i put the HD out of the server an put it in an externaly usb HD Case and connect it to my Laptop for example or in a other Server and can normaly read all date (Filesystem ext3, FAT or NTFS) with the explorer.

So when this is posible with your solution it´s fine. I hope it´s now clear or i thing wrong?

That should work.

That should work.

add a physical drive to vm

What I would to know is if I have a VMID say 777 and I would to mount a physical drive to be mounted to this machine in addition to the virtual disk
so that I have a drive dedicated to this KVM machine.
Can I do that?

Thank you

 

[dietmar]

Yes. This thread explains how to do it.

This will show you how to enable a physical ide or sata drive so it is accesible from the guest OS. It's really very very easy - I use mine for much the same as yours, a 1TB physical drive that contains the sites/mail/etc, whilst the server itself runs virtually
