This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enig10E2A397132E254BEE6C5522 Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: quoted-printable I've just thought of something - the situation where geom_label detects=20 multiple "same" labels is actually very similar to that of=20 geom_multipath. Obviously this doesn't apply 100% to UFS and other=20 filesystems' labels (except if there's a way to identify different file=20 systems by their superblock, for example timestamp of creation?), but in = case of "manual" labels, if the unique ID matches and the label string=20 matches, it's probably the same device. Currently, geom_label discards "additional" devices with the same label, = and I remember there was a discussion about if that should be changed=20 (though I don't remember the conclusions). It would be useful if=20 geom_label would work the same as geom_multipath in this case (i.e.=20 failover to "next" device, add new devices with same label+id to the=20 pool), or even if geom_multipath were merged in geom_label.
