Install Proxmox and DRBD ont the same disk

[Fred91]

Hello,

I plan to use Proxmox in a production environnement and I want to use the following configuration :

- 1 main serveur which will be a big serveur on which will run most of our critical VM.
- 1 backup server, a smaller machine, on which will run non critical VM and wich will be used temporarily if my main server goes down (long maintenance or crash).

I plan to use Proxmox cluster and DRBD but my problem is that Proxmox needs a complete harddrive during install. For DRBD I need an other drive.

This won't be a problem in my main server as it will be equiped with 2 disks in Raid1 for Proxmox and 4 disks in Raid10 for DRBD

But in my backup server, I will just have 2 disks in Raid 1.

Is there anyway on my backup server to tell Proxmox not to use the entire volume during install ?

Should I install a debian first, configuring my partitions as I want (ie one for Proxmox and one for DRBD) and then manually install Proxmox on it ?

Thanks for your help and advices,

Fred

no, you just can select which volume.

but I assume you can create 2 raid1 volumes on these 2 physical disks via the raid management software.

Thanks for your reply.

That's what I thought at first time, but I'm not sure my controller can do that (SAS 6/i on Dell R300).
By the way, I think I can upgrade to an controller wich an handle multiple virtual disks on the same raid array.
