You should be safe as long as the order of slices you give here is the same as it was when device was initially labeled. Of course (as I understand) one of those broken components was really broken, right? If yes, you should 'graid3 rebuild' it immediatelly after 'label' command. If no, you should still rebuild one of them after labeling it. --=20 Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
