Hi all,
I have a box with 4 x 120 GB EIDE drives which I want to convert to FreeBSD 5.4 ( it's an old SNAP 4500 from Snap Appliance, now owned by Adaptec, running a custom build of Linux)

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.



See gmirror and geom.

Thanks for the links , but i'm not too sure what steps I ought to follow.

I basically want to have the RAID 5 across ad0, ad1, ad2, ad3 , and the partitions on top of that. and then build my system on top of that (as if it were a hardare RAID controller, and I'd be installing on top of amr0s1, for example). I think this should be doable, right?

So, should I
1) Boot up with Disc 1, install minimal config, reboot
2) setup GEOM RAID 5 on all the discs ?
3) edit fstab to point to /dev/[what??]/[what else] instead of /ad0s1[abef] ?

or

boot up with CD 1, run GEOM, build the raid 5 from here before installing anything, then install on top?

thanks for your all help :)

Beto
