I built the new btrfs-progs 3.12 recently. I note that the version
information doesn't seem to match this:
# ./btrfs --version
Btrfs v0.20-rc1-358-g194aa4a
Regardless, I was trying to use btrfs send (which worked in the older
btrfs), and failed. Here's an example:
# ./btrfs send -vvv -p /snapshots/bo /snapshots/bp > /dev/null
At subvol /snapshots/bp
ERROR: open @/snapshots/bp failed. No such file or directory
Any idea what might be going on here?
Here's the volume information:
# ./btrfs sub show /

There was a bit of a hiccup in the versioning with the 3.12 tarball, since the version policy had just changed with it, and (I gather) the tarball prep script hadn't been updated appropriately. I believe a patch has already been applied to fix the problem (the patch was certainly posted on this list, but I haven't tracked whether it was actually applied yet) so the same problem won't happen the next time. Meanwhile, btrfs properly reports v3.12 here, but I pull and build from live-git, and the v3.12 tagged commit simply happened to still be current HEAD last I updated. That does explain why the problem with the tarball version wasn't discovered earlier, however, since people (including the devs) building from live-git saw the expected v3.12; it was apparently only the process of preparing and releasing the tarball that was affected by the version bug. -- Duncan - List replies preferred.
