A few things you could do... This will read for 1 second, then pause for one second. Hopefully making a nice consistent blinking light for you to find in your server. export baddisk=/dev/rdsk/cXtYdZ while true ; do dd if=$baddisk of=/dev/null bs=1024k count=128 ; sleep 1 ; done But if you don't have lights or something... The safest thing for you to do is to zpool export, then shutdown, remove one disk. Power on, devfsadm -Cv, and try to zpool import -a When the bad disk is gone, you'll be able to import no problem. If you accidentally pull the wrong disk, it will not cause any harm. Pool will refuse to import. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
