Greg is correct on all counts. You have to create the MD devices from the "setup software RAID" option, prior to formatting anything. After you do this, you will have to create your new file systems (EXT3, etc.) on those MD devices, not on HDA or HDB. You are building layers. It seems as if you have tried to put layer 2 on top of layer 0, instead of layer 1 (RAID) on top of 0 (the raw partitions), and then 2 (the file systems) on top of 1 (RAID). Additionally, since you are trying to mount both file systems on slash, you may not realize that unix sees everything as one single file system. You have one, mounted at slash (the root FS), and others mounted at various mount points thereunder. You should not think of software RAID as a file system which must be mounted, but as a partitioning layer gwhich must be created before you can mount anything. For example, if you have HDA1 and HDB3, of identical sizes, and you wanted to operate a RAID 1 device using those partitions, you would create a device called MD0, by using the RAID setup tools appropriate (or the installer if it supports it, which yours' seems to do). Then, instead of having HDA1 or HDB3 any more, you will have only MD0. You will make one file system, on MD0, and leave the HDA1 and HDB3 devices alone, as RAID's md0 is now handling them.
