There is a manual page for gmirror already in -CURRENT (if you haven't checked it out already). If you want to migrate without dump(8)/restore(8), it is possible, but risky. First you need to find out where vinum stores metadata (I don't know) and do dd(1): # dd if=/dev/<disk0> of=/dev/<disk1> skip=<N> Where <disk0> and <disk1> are your mirror's components and <N> is the number of sectors used by vinum (if they are stored at the beggining). You can increase block size for dd(1) to speed up things, but it will confuse 'skip' argument. Then you should create the mirror by using gmirror command: # gmirror label -b round-robin <name> <disk1> # gmirror load # gmirror insert <name> <disk0> But keep in mind that this is a risky procedure and I haven't tested it. -- Pawel Jakub Dawidek http://www.FreeBSD.org pjd_at_FreeBSD.org http://garage.freebsd.pl FreeBSD committer Am I Evil?
