The reason for this requirement is to stop you from shooting yourself in the foot and overwriting a file system. > so I decided to install new FreeBSD-3.1-stable to support disk > mirror so that when something happen and no technical guys in, I can > only tell someone to switch the disks and I can repair the bad fs > remotely. You don't need to "switch the disks" with Vinum. It just carries on running. With ccd, you need to reconfigure and reboot. > But I really doesn't find the root fs can be mirrored by vinum!
