This is the second part of an entry that was way too huge to post as one. The first part was Building The New VBOX.
After I was finally able to configure my RAID setup in Ubuntu, I halted the system to assemble everything. Shock and horror! Just before the screen went black, two large FAILED error messages appeared, informing me that an error had occurred when stopping the RAID arrays. Was I surprised? Not really.
Once again I consulted the Great Interweb Oracle, a.k.a. Google. From what I gathered when reading the Ubuntu forums and bug reports, the posters considered it to be a bug that resulted in the RAID array being dirty on every boot. This, in turn, meant that one of the disks would be rebuilt on every boot. A rather useless RAID setup, in my humble opinion.
