<hr />
<div>We do not support '''Software RAID (mdraid)''' in offical Proxmox kernel.<br />
<br />
== Reasons ==<br />
The basic reason is that proxmox.com want to offer support for their system, and software raid would cause unjustified burden for us.<br />
<br />
The problems are:<br />
# Most system admins are unable to recover from a software raid error because they never read the documentation.<br />
# RAID1 is not the onyl raid level - I we want to fully support software raid we need a quite complex interface to configure that (RAID5, RAID10, ..)<br />
# We want to use LVM2 (snapshots). This adds an additional level of complexity, i.e. if you recover or if you want to extend your system by adding harddisks.<br />
# One single failed disk can make the whole system unusable - we observed this with sotware raid - but never with hardware raid<br />
<br />
* The developers know that Proxmox VE will not work with soft raid [http://www.proxmox.com/forum/showpost.php?p=4406&postcount=3]<br />
* It creates problems in proxmox special setup<br />
* May stop working after an upgrade<br />
