(I've just started testing) If gmirror kicks one disk, you might end in an unfortunate situation on the next reboot. Since gmirror won't use the kicked disk, gpart will take it an make the partitions available as <diskX>p#. glabel might use these instead of the labels on gm0p#. Ant then you use the kicked disk. To avoid this, do not use labels but refer to the partitions only as gm0p# (or with the journal as gm0p#.journal). Nicolas -- http://www.rachinsky.de/nicolas
