I just bought 2 x 1TB discs and a PCI RAID controller card. The controller card can be configured by pressing F4 during bootup, and I have setup the two discs as a RAID1 array. Available space is now 931GB. I had expected the controller card to present the RAID1 array as a single disc to the rest of the system, but YaST sees each disc separately as /dev/sgf and /dev/sgg. So I’ve now setup a software RAID1 array, using YaST, which gives me my single, virtual disc /dev/md0, but has reduced my freespace on the empty disc to 860GB.
Is it possible to just use the hardware RAID setup?
