Bug Description
I'm installing the daily build of Kubuntu as of 9/21. I created a RAID0 out of partitions on three
disks. I then marked that as PV for LVM. I also marked some free space on one of the drives as a PV
for LVM.
The problem is that there is no way to control the priority of the two PV's. That is, I can only
associate them in a set, but I cannot be sure that the LVM won't put the normal partition first.
Naturally, what I want is for it to use the RAID first and then only when that fills should it spill
over into the regular partition.
There needs to be a way to control this.
Aside: when setting up RAID, do you make sure that the stride and block size are offset properly for
whatever filesystem is being installed? I understand that ext3 likes to space information evenly on the
disk, and if that spacing is a multiple of the block size times the number of disks, you'll defeat the
much of the point in using RAID0.
Thanks.

BTW, besides this (which may be just a result of my unfamiliarity with LVM), I
think the partitioner that comes with Ubuntu is absolutely brilliant. I just
thought you should know that. :)
