The best reason I can think of for 2-disk RAID5 is upgrading a 1-disk setup to 3-disk: #1 - RAID5 the two new disks (3-disk setup -- 2 running) #2 - Copy the old disk to the new RAID5 #3 - raidhotadd the old disk I've done this twice now but had to use a tape drive to backup first. Mind you,

Q: on root/swap mirroring

I've recently had a chance to set up some root mirroring under Solaris (v2.6 7) using DiskSuite. In Sun's setup they have to specify a partition (small one like 8-10mb) for a metatable database to help point to partitions to boot from as well as general mapping information. I'm not that
