The recent "Messed up creating new array..." thread has someone who started by using the whole drives but she now wants to use partitions because the array is not starting automatically on boot (I think that was the symptom). I'm guessing this is because there is no partigion ID of "fd" since there isn't even a partition. I'm on the verge of re-doing this array with 11 full drives (/dev/sd? as opposed to /dev/sd?1 and /dev/sd?2). Will I have the same problems with booting? I like the idea of not having to partition the drives but not if it is going to cause hassles. I realize that there could be a potential problem if I need to replace a drive with a slightly different model that is slightly smaller.
