I have found the exact same problem with 10.0 when trying to do this as well. My natural preference for servers I was putting in at work is mirrorred RAID 1 on the boot disk(s). I am presuming the same problem has persisted to 10.1 (I haven't tried it yet). When I was doing work on this I found when reverting to my 9.2 CD's that it worked fine. I did a lot of messing around and reinstalls to see how this problem was happening: - installing 9.2 to RAID1 partitions works fine - dropping in a 10.0 DVD and using the "upgrade" function following a successful 9.2 install (which I generally avoid but used for testing this) worked and left me with a fully functional 10.0 install on RAID1 partitions. After I tried that I was surprised how the 9.2 worked but the 10 didn't... not something I have generally run into with Mandrake installs. You can try an upgrade from 9.2 or jsut creating the filesystems with 9.2 and rebooting to boot a version 10.1 install- maybe see how these procedures go. Also watch carefully when you create your RAID1 filesystems- I noticed that one time when creating them, the version 10 install did not correctly set the chunk size on one of the partitions- one of them did not have a chunk size specified, and when the installer tried to mkraid in the bankground it consequently failed.
