Re: RAID10 and Kickstart



Actually, I think it can be done, essentially just how you wanted to do it, but a little simpler.
Since what you want to do is create software raid 1 of hardware raid 0's
Create identical hardware raid 0 sets on each controllers
for example
c0p1 = 128mb, c1p1 = 128mb
c0p2 = 8192mb, c1p2 = 8192mb
c0p3 = 2047mb, c1p3 = 2047mb
c0p4 = rest of disk, c1p4 = rest of disk


in software raid,
you would create raid 1 set's of
c0p1 - c1p1 : /boot
c0p2 - c1p2 : /
c0p3 - c1p3 : swap
c0p4 - c1p4: /data(ie rest of disk)

you get the idea...

So really your kickstart would only have to know about raid 1 setup
since the raid 0 would be handled by the controllers.

Unless of course, both your controllers only support jbod,
then I think you should be looking into lvm

Yeah, as far as I could tell, there was no way, kickstart or
otherwise, to install a system on to a RAID10 array.  The problem
is, I have two controllers with 8 120GB drives each, and the only
configs that make sense are a stripe of mirrors between the two
controllers (/boot would be its on RAID1 array with a small
partition from the first drive on each controller) or a RAID5 of
all the drives (again, /boot on its own small RAID1).

The former can't be done in kickstart, although I can setup a large
RAID10 data partition during the %post run.  The latter is great,
except with these controllers, I have a problem with corruption
when the RAID5 array drops a bad drive.

Short answer: no.
