If it is for other reasons, do you have to stripe ? Yep, performance. It's for a database machine. Adding disks will be a very rare occurrence, resizing LVs an uncommon occurrence. So having LVM just do the sizing of LVs on the striped mirrors is a managment advantage. It doesn't really sound like LVM is the right tool for doing the striping itself though. md can do the striping but apparently it's advised to take everything offline first if the striping is part of a stack of storage systems. That is a bit inflexible but better than what LVM can give me and, like I said, adding disks will be rare.
