FYI - here are the relevant parts of a kickstart I just used to build a 26
disk system with hardware and software raid and the resulting df of the system
after it was built. (CentOS 6.2, in case it matters)The BIG problem I had was
that there are 2 different LSI controllers, as well as the motherboard SATA and
the controllers always came up in a random order (really) and the clearpart and
zerombr commands do not seem to work as advertised. Existing software raid
arrays were getting mounted by the kickstart and the LVM creation would cause
the kickstart to fail.I solved these problems with the %pre script at the end
of the kickstart, which, of course, runs
pre-kickstart.################zerombrclearpart --all --initlabel# some of the
LSI disks show up before the MB disks!# sda and sdb are on the MB, sdc is a 16
disk hardware raid10 array, the last 2 external disks are spares# the 2 disks
next to the spares are swap.bootloader --location=mbr
