R> I've got a geom based file system that is running under 2 geom R> modules: multipath and journal. Solved the problem, so here's some notes for the archive: - the answers were hiding throughout in the freebsd-geom mailing list archives, I just forgot to look there initially. - this was a single data disk that was improperly partitioned/sliced in the beginning, therefore the metadata information was being picked up twice and auto creating the journal device under each device. - if the journal is being picked up multiple times (ie slice + partition), then remove one of the formatting options (via dd if=/dev/zero of=/dev/xxxxx bs=512 count=32) so only 1 journal is picked up. Then do "gjournal clear /dev/xxxxx" to properly remove the metadata. - hardcode the gjournal labels for situations like this, as it'll stop it being autoloaded under multiple devices. - gjournal hardcoded provider labels are up to 15 characters long, so long device names can be a pain (like "multipath/xxxx0s1a" is too long). Probably a few other notes that I've forgotten, but that'll get you on the right path. R. --
