Hello,
I've been considering buying another hard drive for my FreeBSD
machine, and building a RAID with my current hard drive so that both
drives are treated as one.
Do any of you have experience in this area? Is this advisable? I'm
assuming I'd be looking at creating a RAID-5? Can this be done
without reformatting my current drive? Does this setup work well? Do
you have any general advice for me? I need to know if there is risk
involved here.
Thanks in advance!
Joe,
It depends on what you need to do. If you just want data integrity
then
you need raid 1 - mirroring and GEOM is your friend. There is a good
section in the Handbook on setting a GEOM raid 1 without formatting
the
original drive.
If you are also looking for more drive space, then raid 5 gives a
measure of both.
In both cases, the warning of backing up the system first applies.
Hmmm..... What I need is more drive space. Should I look at GEOM
rather than vinum? Do you know whether the drives would need to be
reformatted in order to setup the RAID?
I'll definitely heed your advice on backing up the drive first!
