      Howdy!

            I am trying to test the fault management system, so I yanked out
    one of the disks in the mirrored rpool. It detects the failure and resilvers
    the hot spare, syslogs the condition ,, but the fault management system
    doesn't seem
    to notice (as per fmadm faulty -a see below) and I don't get a
    notification...
    Shouldn't fm facility see this "error"? Or how can I test for failed disk
    detection/notification, removing one of the disks in a mirrored volume should
    be enough?

    root at live-dfs-2:~# zpool status rpool

    status: One or more devices has been removed by the administrator.
            Sufficient replicas exist for the pool to continue functioning in a
            degraded state.
    action: Online the device using 'zpool online' or replace the device with
            'zpool replace'.

      fmadm sees only historical rsync fault.. ??? in which I did get a
    notification.
