Hey Well my sata disks are recognized by installer and now i'm in the next painfull step of creating RAID 1. Using this tutorial: http://www.howtoforge.com/linux_software_raid it stops for me when it tries to create an array. "No RAID partitions available" All four partitions for 1 disk in total 8 partitions are set for RAID! So i went to console (ALT+F2) and typed: mknod /dev/md0 b 9 0 mdadm --create -l 1 -n 2 /dev/md0 /dev/sda1 /dev/sdb1 and array was successfully created: cat /proc/mdstat gives me an md0 array.. Now i wanted to do this for all other 3 partitions (in total i have 4) using same steps: mknod /dev/md1 b 9 0 mdadm --create -l 1 -n 2 /dev/md1 /dev/sda2 /dev/sdb2 It asks me for creating array, i type 'yes' and then it gives me an error: mdadm: SET_ARRAY_INFO failed for /dev/md1: Invalid argument Going back to first console, installation still gives me "no raid partitions available". Anyone knows what's going on here? Some hints would be appriciated..
