anyone have any good howtos about doing mirroring+striping on 2 drives
with LVM2? best i found is the lvcreate man page, which indicates
using the switches "--stripes 2" and "--mirrors 1". just wanna make
sure that's all i need to know.
also, opinions of MD vs LVM2 for mirroring+striping on 2 drives?
