Yes, if two disks belonging to the same mirror go down, I lose my data. But if two disks which are not from the same mirror go down, I would like to be able to boot up without any problems. And as someone else mentioned, what else am I going to do with those 200mb? I'd rather maintain symmetry and not have to worry which disks /boot is on, as I'll know that if the data drive survives, then I won't have any problems with the boot drive either.
so, is your / on a 4 spindle mirror too?
N-way mirrors require every write to be done N times.
No, / is on a 2 raid 1 arrays which are striped using LVM. And the N times write penalty doesn't really apply to boot, since it rarely gets written to.
