Is Proxmox supporting Software RAID (mdadm) ?

I use a server of OVH. Its a model: X8STi Supermicro
With two Harddrives: model: 2 x Western WD10EADS-OOPS (Software Raid)
CPU Intel® Core™ i7-920

Software Raid setup:

mdadm --misc --detail /dev/md1
/dev/md1:

UUID : 143a2bff:1fdf830e:f4b67177:f022a824
Events : 0.39

Number Major Minor RaidDevice State
0 8 1 0 active sync /dev/sda1
1 8 17 1 active sync /dev/sdb

With OVH version of Proxmox 1.3 Real bad performance.
After upgrading to 1.4 Much better but still not stable.

Procedure is used: http://travaux.ovh.net/?do=details&id=3077

Question is the 82801JI (ICH10 Family) 4 port SATA IDE Controller of this server
giving me the troubles or software RAID ? Driver or bad Hardware ?
How to find a solution ? Support don't really has a good answer.

Okay sorry guys i found my answer ppff http://www.proxmox.com/forum/showthread.php?t=838

Looks like i the software Raid is the trouble its not supported ... must use hardware Raid or non .. to make it work..

Software raid is not supported by proxmox ve team.

It is not difficult to setup & get working & I have had 0 issues with it (I do have a real UPS for each server -- about 1500va ea).

Search for HOWTO: and you might come across my thread about setting this up.

There is a "filesystem" section that explains how to optimize it. Did you use those options?
