Didn't have any issues. One got full, however, so I decided to buy fresh disks and make a new one. Did exactly what I did the first time: fdisk/label/copy data to one disk, add it to the mirror. added another disk, got to DEGRADED 100%. Gmirror seems to hang there forever unless you reboot - Now, system won't boot (aka /bin/sh or pathname) -> why? -> mount gives "incorrect superblock" for /dev/mirror/gm1. Took gm1 out of fstab, or course, then ran fsck, which echoed the concerns about incorrect super block. Rebooted, now fsck just says, "Could not determine filesystem type". What's my best way to proceed? It took all &*%#@ day to mirror up those 2 disks, and I'd rather not repeat the process if there is something I can do to recover the data as is - only if I can trust the mirror after recovery, of course. Thanks, Steve
