How Can I Install Proxmox on a Raid 10?

[Danielc1234]

I just upgraded our server with 4-WD drives and in the bios set it for Raid, then on the bios software set the drives to Raid 10.

I then booted to Proxmox install cd and proceeded to install, but noticed it was only installing on the 0 drive. After the installation, looked everything was fine, but when I rebooted the system to enter the proxmox, it acts like nothing is there. I wont boot to the Proxmox.

Any ideas?
Thanks

Hi,
this sounds like that you use a fake-raid. If it's a true raid, the os see only one big disk and not four single disks.
With lspci you can look, which raid-controller you have.
pve don't support fake-raid and if you wan't a raid-10 becours of the speed it makes sense to get an good hardware-raid-controller.

Udo, thanks for the reply. Yes unfortunately it is a 'fake' raid 10. I have looked around the forums and see others with this same issue. Looks like more money to get this thing going!

Do you think since I only have one server running the Centos, PHP, simple email server and SQL all together that I should even be thinking about VT?

Is there any speed advantage or other advantage to use Proxmox?

Hi,
i don't know VT - i only know vmware (esx v2 til v4) and proxmox. At the company we use vmware and proxmox and i'm very happy with proxmox (but some smp-windows-guests runs better on vmware - many guests runs equal or better on proxmox
I make good experience with opensource-software and don't like the software from redmond...

But most of your clients (email, centos) are predestined for openvz: marginal performance-lost. Good io and cpu-performance. And, this time you have only internal storage (if i understand you right), so you have no problems, that openvz-clients are only use local storage.

The money for a good raid-controller is a good investment.
Take a look at http://www.proxmox.com/forum/showthread.php?t=3000
for some perf-values.
