To mirror the root partition to another: # mkdir /mnt/root # mount /dev/<ROOT-MIRROR-DEV> /mnt/root # cd /mnt/root # /sbin/dump -f- / | restore -rf- You will not *need* to umount the root partition. (If you wanted to hot-swap between them, I'm not sure it's possible on FBSD. There is a ``pivot_root'' syscall on linux, though.) To mirror another partition, do mostly the same thing, but replace / with the partition in the dump line (and make sure the correct destination is mounted on your current directory for the restore). Dump/restore is pretty much the accepted way of doing this. -- Josh _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
