Proxmox in Fujitsu RX100 S6

[robertodiaz]

We just purchased a Fujitsu RX100 S6 with LSI MegaRAID controller. We set the two 250GB hard drives in raid1. When we start Proxmox 1.7 to install does not detect the disks in raid1, we must choose between the disk sda1 or sda2. We tested a Debian Lenny 6 and detect the disks in Raid1.

Is there any way that Proxmox 1.7 detects disks in raid1 ?

Best regards.

Hi,
if you see two disks the raid controller aren't a raid-controller! It's a fake-raid: the raid is doing by software (if you wont sw-raid then use the linux sw-raid - i assume a better quality than lsi-crap).
Software raids are not supported by proxmox, but there are some people which use this (search in the forum). But if you have the chance to get an real (fast) raid-controller, then use them.

Maybe you're right.

On the Datasheet's server I can see that:

Onboard or integrated Controller
RAID Controller Integrated RAID 0/1 or RAID 5/6 controller for SAS base units (option, occupies one PCIe slot).
See under Components RAID controller
SATA Controller Intel® 3420 Ibex Peak PCH Platform Control Hub, 1 port used for accessible drive
4 port for internal SATA HDDs with RAID 0, 1, 10 for Windows and Linux;

So, do you think the server haven't got the RAID controller, right ? It's an option ! The server has a software raid ?

Best regards.

Hi,
yes - if it's a real raidcontroller you can't see the disks - you see only one disk which the raid-cntroller defined. Unfortunately also on server boards the manufactures use crappy softwareraids...

udo, i'm not an expert, and think you're right (as always ), but i was thinking: my not be the logic (raid) volume just not configured?

Hi,
with an real raidcontroller you don't see the single disks. Except, you defined them as "passthrough" disk (to use the benefit of raidcontroller cache).
The costs of an good real raid-controller are to high to use them on a motherboard. The manufactures go's two way (both are bad): 1. use fake raids (mostly today) or 2. use very slowly real raid-controller like the lsi SAS1064 - SUN use this things in the x4100...
Both chooses makes no fun!
