Note also that the information I can provide is only for doing mirroring, as I haven't played with RAID 5. Mirroring can be done in a "non-destructive" fashion, which I don't believe is true of RAID 5--I think you'll find that you need a "space" where you can dump filesystems while you build the RAID 5 partitions, and then copy it all back, which as you can imagine will get pretty ugly. Assuming you've gone through the process on a practice box, and you have a spare disk, you should be able to do a lot in six hours. I have to say, though, that your system would probably benefit a lot by having the filesystem layout "revisited". Two of the things I'd be concerned about are: it appears to have no (separate) filesystem for /tmp, which is probably why / is so large the amount of space that's being used on /var Tony -- Tony Landells Senior Network Engineer Ph: +61 3 9677 9319 Australian Clearing Services Pty Ltd Fax: +61 3 9677 9355 Level 4, Rialto North Tower 525 Collins Street Melbourne VIC 3000 Australia To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
