Re: [K12OSN] New Building's LTSP Server

If you chose Fedora, please note that by using any software RAID for the /boot partition, you won't be able, later, to upgrade the system using the handy "preupgrade" command. By repetitive use of "preupgrade" we are now able to run a K12 over a F14 with no glitches. "preupgrade" requires either a hardware RAID for /boot or a single drive partition, but won't work on a RAID boot partition. We chose to partition the disk so that /boot appears on a single drive and everything else is mirrored on RAID1.

Also, like I said avoid RAID5 even if you have a real hardware

I am actually a fan of RAID 5 for a lot of situations, as I find it
certainly fast enough for my purposes, plenty reliable, and very
efficient with storage.  But a RAID 1 or even "RAID 10" setup, depending
on the specific situation, would also work well.
I used to run RAID5 also but after I had a number of RE2 disk failures
(thankfully never two before the array was rebuilt) and noticed some of
the related performance problems I went to RAID1.  Have a look here for
some arguments:
