RAID not detected

[hestin]

hi
im installing proxmox ve on a server series machine (supermicro x7dbr-e) with 4 disks and raid support. I configured raid 0 using the raid utility with all the 4 drives. but while installing proxmox all the 4 disks are shown seperate and asks for destination.
what to do??

I've had the same problem with my ASUS P7P55D Deluxe Motherboard. I defined a RAID5 with 4 disks in the onboard RAID Bios. at the end I could not choose one big partition. The PVE installer just gave me 4 possible disks to choose for installation.
I think the PVE installer should be improved a little bit.

Those MBs does not have a real RAID controller, instead that is what we call 'fake raid' (a way to fool customers). We do not support software raid for various resons (search this forum).

ohhh.
thankyou for your kind reply.
but it has both intel and adaptec raid utilities.
and also in the MB manuals they never mentioned its a fake raid that the MB has.

You MB contains a intel "Intel ESB2 SATA" controller (they call it 'host raid', and it is definately a 'fake raid'). That is why the MB is quite cheap ;-)

See 'Firmware/driver-based RAID" in: http://en.wikipedia.org/wiki/RAID

i know proxmox wont support soft raid.
but for the sake of simple backup can proxmox be installed on a debian lenny which is installed over soft raid?

Some people do that.
