Partitioning questions

[Alex]

Hi,

I'm trying to install FC14 x86_64 on a quad-core AMD box with 4 1TB
SATA disks, and have some questions about partitioning.

I'd like to create a RAID5 array with no spares, using all four disks.
There isn't room in the chassis for more disks, and they will never be
replaced with larger ones. Should I even worry about LVM?

If so, do I manually create the RAID5 partitions (and devices) that I
want to use, then wrap them in LVM?

By default, the installer creates LVM partitions, but it seems they
must be deleted to create the RAID partitions, correct?

The installer is very non-intuitive (and more difficult than it needs
to be) if you want to just create RAID partitions and not LVM.

Thanks,
Alex
