This unclear term is taken from the wording of d-i. Here the exact steps until the problem showed up: 1. I used nothing else than the d-i partition tool on these hard disks and the hardware doesn't provide any RAID specific support. 2. I created two partitions (type fd) to be used for software RAID and combined them to a RAID1 /dev/md0 device, but the d-i CD uses devfs, so it is visible as /dev/md/0 there. 3. I used this /dev/md/0 as a physical volume for LVM. 4. Because of an install problem (Debian bug #382692) I had to reboot. 5. To make a clean start for the next try I decided to delete (but not erase==wipe) the software==md RAID partitions. 6. Repeating from step 2 the installer presented me with the above mentioned error message. Thomas -- Email: thomas@intevation.de http://intevation.de/~thomas/
