Subject:   RAID 5 with Vinum
Message-ID:  <NDBBKCNFGLGFDJGFGEECKEOBCDAA.bhui@mail.com>

next in thread | raw e-mail | index | archive | help
I'm thinking about setting up a RAID 5 system with Vinum using 4 IDE HDDs.
I've looked through the man pages on vinumvm.org, but I still have one
preliminary question:

when installing FreeBSD with the intention of setting up RAID 5 using Vinum
on 4 hard drives, do I install the whole OS on one hard drive and then use
Vinum to arrange the file system on the remaining 3 hard drives, or do I
install the OS on all 4 hard drives (assign space that fills up all 4
drives) and use Vinum to work out the RAID 5 itself afterwards?

One other question about Vinum I have:

If I have the FreeBSD OS on 2 hard drives without any RAID/Vinum setup and
then decide to add two more hard drives and setup RAID 5, is this something
that Vinum can easily do, or is it easier to reformat all 4 drives and start
from scratch?  If Vinum can do this "on the fly," what Vinum commands/steps
would I use to do it?

Thanks.
