Should I just stick with mdadm for my mirroring and striping needs?
You can do it today with some hassle or wait until someone implements a
feature called 'generic layering'. The feature really means, treat some
LVs as PVs!
How can you do raid10 today? Create two raid0 LVs. Lets us call these
lvgroup0/lv0 and lvgroup0/lv1. Now create raid1 lv in lvgroup1 where
lvgroup1's PVs are lvgroup0/lv0 and lvgroup0/lv1.
Isn't that a rai10 volume?
To increase the chances of surviving a double-disk failure it would be
better to raid-0 a bunch of raid-1's.
Are we sure there are no deadlock problems with LVM2 layered on top of LVM2?
