I want to setup software Raid 5 , and I want it to affect ALL partitions, including / (so if any one of the drives fails, it will still boot up properly). I am planning on using GEOM, but open to suggestions.
I don't think it's possible -- the loader doesn't know about the mirror even in a mirrored / setup; it justs treats one of the disks of the mirror as 'the boot disk'. It's not until the kernel is loaded that gvinum RAID-5 can do something.
Would the same be true (not possible to boot) for a RAID 1 + 0 with GEOM?
So, in your case, the loader would read random RAID-5 data instead of a kernel and refuse to boot. IE, it's not possible until someone writes a RAID-5 capable loader.
right - so that's why I couldnt find any reference to this anywhere :)
I would advise you to either use gmirror for booting, or define a few gvinum mirror plexes (it is possible to boot from a mirrored gvinum setup although it's tricky to get right).
I guess I could create a boot slice in 2 of the drives, mirror that with gmirror and use that to boot. Then RAID-5 the rest of the drives (minus the size of the boot partition in the other 2 drives of course).
