[-- Attachment #1 --] I've just thought of something - the situation where geom_label detects multiple "same" labels is actually very similar to that of geom_multipath. Obviously this doesn't apply 100% to UFS and other filesystems' labels (except if there's a way to identify different file systems by their superblock, for example timestamp of creation?), but in case of "manual" labels, if the unique ID matches and the label string 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 (though I don't remember the conclusions). It would be useful if geom_label would work the same as geom_multipath in this case (i.e. failover to "next" device, add new devices with same label+id to the pool), or even if geom_multipath were merged in geom_label. Comments?
