1. When using fdisk, is it really required (or a "good idea") to create the partitions as type "fd"? I've typically just created a regular Linux partition, and would let mkraid to it's thing. (As a result, it seems strange that I ran into #2 below since I didn't do this step of changing the type.) 2. I can't seem to find a document describing how software RAID really works technically. (Yes, I could read the source, but I'm not the most proficient C person, nor do I want to work all weekend looking at the source either.) I had a problem the other day, where I had a md0 device that the system was not able to mount (logical disks mounted from a SAN). Because the system could not mount the disks, it would fail to boot at the section where the system would attempt to auto-detect md0 and would drop me to single-user mode type prompt. Taking the directory out of fstab, and tried to find something in /etc/rc.d/init.d that was trying to do stuff with the md devices at boot but couldn't find anything. Ended up being a problem with an old modular driver, and had to create a new initrd with an updated driver, but I was stuck for a second (well more than a second really). 3. Is "persistent-superblock" supported with Linear and RAID0? I think chunk-size is only supported in RAID0 and higher, but Linear will just skip the configuration with an informational warning at boot.
