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 /
    /
            Name:                   @
            uuid:                   e5e505d6-1309-8447-b51e-73f08c9401d1

Here it seemed that you changed your default sub-volume.(259 not 5)
I sent a patch before to fix this problem, it has not been pushed into chris's master branch, patch url is:

https://patchwork.kernel.org/patch/3258971/

But is has been pushed into david's latest integration branch , you can pull from:

git pull http://github.com/kdave/btrfs-progs.git integration-20131211

Hopely it can fix your problem.^_^


Thanks,
Wang

I see Wang Shilong dealt with the snapshot issue; I'll tackle the version 
thing.

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.

After compiling this version the above tests works.  Now, however, the
receive fails:
