[PVE-User] RAID 10 with proxmox

Hi Muhammad,

Raid 10 is not common for a fake Raid, I would presume it is real Raid. 
Do you know what Raid Controller you have ? Normally, the hardware 
drivers are included in the linux kernel, and Promox kernel (the last, 
2.6.32-6 is based on RHEL 6 one) contains a lot of them. The Proxmox 
team even includes more drivers if they are available and are requested 
by users.

But the normal way to setup Raid volume (for example Raid 10), if it is 
a real hardware Raid Conttroller, is to enter the Raid bios Setup (often 
Ctrl-A when you power on the server), and inside this Raid setup, you 
configure your Raid (selecting the level, the disks included in the 
volume, and so on, see the documentation of your Raid Controller). Then 
there is a long Raid initialization phase, and only when it is 
completed, you can try to install Proxmox-ve. If the Raid controller is 
recognized, the installer will see one disk, your Raid 10 volume, and 
happilly install on it.

Be sure there is a Battery Board Unit (BBU) on your Raid Controller if 
there is Ram cache.

Hope this helps.
