    sys/geom/mirror      g_mirror.c g_mirror.h 
  Log:
  - Add kern.geom.mirror.disconnect_on_failure sysctl/tunnable (default to 1
    to preserve currect behaviour). When set to 0, components are not
    disconnected - gmirror will try to still use them (only first error will
    be logged). This is helpful when we have two broken components, but in
    different places, so actually all data is available.
    Such buggy component will be visible in 'gmirror list' output with flag
    BROKEN.
  - Never disconnect the last valid component. If we detect errors there we
    will just pass them up. This wasn't reasonable to deny access to the
    whole provider because of one broken sector.
