graid3 can only use 3
graid5 can use all 4, but is it production ready?
any ideas?
The advantage of using graid3 at this point is that the extra 1TB
drive I have can then go into the backup server which needs more
space anyway.

Take everything I say with a grain of salt, I am still testing these
kinds of setup.
I do not know about graid5, but gvinum is very slow when used in a raid5
config

Just wondering if it is possible to setup a striped root partition
(graid3) and still be able to boot from it. Logically, it doesn't
sound promising, but has anyone tried this?
Thanks!

I upgraded them to 5 x 8g disks

why it can't be say 5 disks+parity?
The reason is in the definition on RAID 3, which says the updates to the
RAID device must be atomic. In some ideal universe, RAID 3 is implemented in
hardware and on individual bytes, but here we cannot write to the drives in
units other than sectorsize

2) -r Use parity component
the raid controler/software thing can reconstruct the data
with only n-1 of the n drives in the array.
in random IO this can be quite usefull, while in sequential read, the
parity drive is not that much of use.

Is it possible to create a (degraded) graid3 array with only two (or one
less than the planned total) providers? I'm asking since I would like to
move from my current one-disk setup to a three-disk raid3 array, but I'd
like the disk currently in use to be a member of the array and I don't have

Maybe you'll be able to create graid3 with md0 as
the third member (based on sparse file for example)
and later emulate a failure (md0 disappears) and
insert your hard drive

is the loss of your data worth less than the cost of an extra hd? if
so, buy another hd. if not, make a clean install?
should read:

important are the goals of learning more about something I haven't used
before (graid3) and getting a larger volume on a limited budget.
Besides, trickery is where the fun comes in. :)
I appreciate the response, though. It's a point I might have raised myself.

I've got a dual-proc machine with 3 ATA drives that I'd like to roll
together in a graid3 configuration. 2 of the drives are 250G, and the
third is 300G. I'm using the raw disk for the two 250G drives (ad4 and
ad6) and the a partition (which is 250G) of the 300G disk (ad9). ad9
looks like
