Either that or I'm misreading you and am totally confused about what your question is... Btrfs-zero-log was previously its own command. In 4.0 it has moved under the btrfs rescue command as btrfs rescue zero-log. That's what I was referring to as the new integrated btrfs rescue zero-log. Then there's a comma, and specifically stated btrfs check --repair (starting with btrfs, thus suggesting an entirely new command as that's what btrfs commands start with), a /separate/ command I ran. I'm not sure where you got btrfs rescue zero log btrfs check, apparently interpreting that as a single command, despite the comma and repeated btrfs, and the hint in "nothing I tried", which suggests several things were tried... So someone's obviously confused, but I'm not sure if it's you or me or both! =:^) >> So I got to use the new btrfs-progs v4.0 metadata-restoration option in >> btrfs restore, > > In man btrfs-restore I only see a -m option, is that what you're > referring to? Yes. That too is new in 4.0, the patch in fact being new enough I wasn't actually expecting to see it in a release until 4.1 or at least 4.0.1. But it works well (except with dry-run, -D, which apparently is falling a bit behind as it still has the too many loops error from older code that no longer affects a normal write-out run, too). =:^) Since I suggested restoring ownership/perms to the person who came up with the patch (his first one restored dates but not ownership/perms, as the date issue was his itch and he scratched it, so I suggested ownership/ perms too, my itch, which not being a coder I can't scratch directly), I'm happy as a kid at Christmas! =:^) -- Duncan - List replies preferred.
