If ad4 is your root device, GEOM prohibits changes to the device configuration on a mounted device. You can either: a) boot into the fixit CD, finagle some symlinks to make 'gmirror' work (I think you need to symlink /dist/usr/lib to /usr/lib) and remove it from there; or b) set 'sysctl kern.geom.debugflags=16' which disables the protection. You activate this at your own risk, since it makes it possible to destroy the root volume while it is mounted. -- Doug White | FreeBSD: The Power to Serve [EMAIL PROTECTED] | www.FreeBSD.org _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
