With Online Disksuite on Solaris systems you can mirror the root filesystem; You boot from one of the mirrors as if it's a normal ufs filesystem, and very soon after booting it does the ODS configuration stuff to bring mirrors online and remounts root. It means that you may have to boot manually (to pick an alternative mirror) if your "primary" boot device fails, but you still get the advantages of mirroring on your root filesystem. You can't stripe or concatenate it, though. I guess that counts as a different weak point in the implementation :-) - mark ---- Mark Newton Email: newton@internode.com.au Network Engineer Desk: +61-8-82232999 Internode Mobile: +61-416-202-223 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
