Re: Cannot create an LVM disk layout on top of SW RAID in kickstart

On a related note, I'm also bumping into the 256GB logical volume size 
limit...and I don't see a way to create a volume group with 16MB extents 
in anaconda.  Anybody else figured out a way to do this?

At this point I'd actually be fine doing all the partitioning in %pre 
and then just instructing anaconda to use the partitions I create, but I 
don't know what LVM/partitioning commands are available in BusyBox 
inside anaconda.
