I am doing a fresh install of SME7.1 on a dell server with 3x 36GB SCSI hard drives. After installation I look at /proc/mdstat and see that both md devices are setup as raid1. How can i set it up as raid 5? I tried installing with option "sme raid5" (wild guess) and no luck. Is this a bug?

Thank you for your reply. It was very helpful. It would have been nice if they mentioned it in the readme.txt for sme7.1 found at smeserver.org
Automated RAID installation
===========================
NOTE: All disks must be the same size for SME Server 7
- The default installation provides the following setup:
- Single disk provides one-way RAID1
- Console screen allows simple addition of second disk to provide mirroring
- Two disks are configured as a RAID1 mirror
- Three to five disks are configured as RAID5 (/boot partition is RAID1)
- Six or more disks are configured as RAID6 (/boot partition is RAID1)
- (bug 2015, 2066) The installer provides options to:
- skip software raid
- skip logical volume manager
- force a raid 1 install on the first two disks detected
- attempt to reserve one disk as a spare
- (bug 130) A script has been provided for conversion from non-RAID to RAID

No it is correct see bug 2492. The default it to now create an array with
spare. So we have the following setups:
1 drive = degraded raid-1
2 drives = raid-1
3 drives = raid-1 with spare
4-6 drives = raid-5 with spare
7+ drives = raid-6 with spare
If you pass the nospare option on bootup then it will revert back to the older
setup.
you can still install RAID5 on 3 disks with the nospare option. I will test it tomorrow.
