BTW, that and the corresponding Metadata, single: entries, both used=0.00, are artifacts of the original mkfs.btrfs, and can be safely removed via balance. I've started doing that here right after first mount of the filesystem, before I stick anything on it, but they can be removed later as well. btrfs balance start -m,convert=raid1,soft <mountpoint> ... should do it. The soft avoids the already raid1 metadata, and metadata normally implies system as well. That does it for me, tho one person said in ordered to get the single system chunk gone he had to use -s,convert=raid1,soft -f (force) as well. (I suspect that might be because he did system first, separately, and force is needed as confirmation for that, but not for doing metadata, which implies system as well. Force would also be necessary going the other way, convert=single, since that reduces metadata/system redundancy.) It just bothers me to see those separate extra and unused entries every time I do a btrfs filesystem df, and that gets rid of them, so I do it, and after that my btrfs filesystem df's are nice and tidy like the should be! =:^) -- Duncan - List replies preferred.
