Using btrfsctl from ubuntu maverick, (built and running on
ubuntu-10.04), I get:
rich@eisenhower> btrfsctl -s snap1 /home || echo failed
operation complete
Btrfs Btrfs v0.19
failed
rich@eisenhower> ls -las snap1
total 4
4 drwxr-xr-x 1 root root 32 2010-07-20 18:25 .
0 drwxr-xr-x 1 rich rich 1324 2010-07-21 12:47 ..
0 drwxr-xr-x 1 checker build 22 2010-07-20 18:21 checker
0 drwxr-xr-x 1 rich rich 1322 2010-07-21 12:44 rich
0 drwxr-xr-x 1 root root 36 2010-07-21 10:47 za-cb
This would seem to indicate a non-zero exit status despite the fact that
the snapshotting operation appears to have succeeded. This makes it
impossible to programmatically check whether a snapshot was created
successfully or not as I will need to explicitly discard the exit status
from btrfsctl.
I get the same results when built from git, except that it identifies
itself as "v0.19-16-g075587c".
I would expect that btrfsctl would return zero exit status when it was
capable of doing what it was asked and non-zero exit status only when it
could not.

Try using "btrfs" tool; btrfsctl is/will be deprecated I think... and
it's better anyway.

Ah! Thanks.
Wiki page needs to be updated then. It shows btrfsctl and doesn't
mention btrfs.
This one: https://btrfs.wiki.kernel.org/index.php/Getting_started
