CentOS - Jan 2017 - CentOS 7 install on one RAID 1

Hi, folks,

   I'm building a new box, and I want three partitions - /boot, /, and
swap, on *one* RAID 1, not three separate partitions. Other than
<alt-f2> mdadm..., *is* there any way in the graphical installer to do
this? All I see is a way to make three separate partitions.

   Pointers to links happily accepted.

       mark, back to googling

the first sentence is in conflict with the last one ("I want three
partitions" vs. "not three separate partitions")

A hardware RAID will provide one device that can be partitioned or use LVM on
one MD RAID (software version).

I don't know the answer to that question, but what I can tell you is 
that I handle software RAID setup in kickstart, creating the partitions 
manually, so that I can replace drives using a shell script.  Making the 
partitions predictable means there's less of a chance that I'll make 
errors during drive replacement, and that I can pass that duty on to 
less experienced co-workers without worrying about it.

If that wasn't clear, I meant to make the two drives into a single RAID 1,
*then* partition that for root, swap, and boot.

Trouble is, it's for this one box. Next box, or the one after, will be
happy with the kickstart as it is.

The solved part: I did the <alt-F2> and created the RAID 1. I went back to
the GUI, and tried to rescan... it didn't find it, didn't show any
drives,
then it showed the two real drives... then it gagged, and crashed, and
rebooted. HOWEVER, when I tried the next time, anaconda's probing found
the RAID, and I'm installing now.

*phew*
