This looks like your both disks has bad sectors in the same place. The error=3D5 is EIO returned from your disk driver. By default gmirror disconnects failed components on first EIO. In 6.1 it won't disconnect last failed component. In FreeBSD 6.1 you can prevent disconnecting any failed components by setting kern.geom.mirror.disconnect_on_failure sysctl/tunable to 0. This won't help you much in this case, though. --=20 Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
