I tested the beta alternate Maverick (10.10) from CD and tried to create a RAID10 array with LVM.
What happens is that the RAID10 array itself is correctly created and it shows the correct size ((N/2)*S).
However when I try to create the LVM for this array it shows a size as if it were calculated from RAID5 size ((N-1)*S).
So what the LVM shows is a *lot* bigger than the actual usable size for RAID10.
I also tried to use this incorrect size and create the LVM. It caused a serious lockup of the partitioner for all subsequent install attempts. So I was forced to take the Live CD and repartition with Disk Utility (also GParted crashed with Live CD).
I also tested RAID5. It worked correctly with correct sizes shown ((N-1)*S). Does the installer mix the RAID10 with RAID5?
