btrfs 3.16.2 does not recognize subvolumes correctly
Hi all,
I just noticed that when doing a 'btrfs subvolume show /' I get the error 'ERROR: / doesn't belong to btrfs mount point', which is not quite true. I get the same error for all the other subvolumes as well. It worked fine until 3.14.1.
Regards,

Hi all,
First of all, I am talking about btrfs-progs 3.16.2 if there was any doubt.
I did some more checking and found the following disturbing results.
I can still create snapshots of subvolumes and the default subvolume (/) without problems. But sending the snapshot fails with the error:
ERROR: /.SNAPSHOT doesn't belong to btrfs mount point
btrfs subvolume list -a /
ID 259 gen 21444 top level 5 path home
ID 260 gen 21443 top level 5 path var
ID 742 gen 18830 top level 5 path .SNAPSHOT ID 743 gen 18832 top level 259 path home/.SNAPSHOT
But then again e.g.
btrfs subvolume show /home
ERROR: /home doesn't belong to btrfs mount point
All this is happening on my laptop running kernel 3.16.3. (Debian).
Interestingly enough I have another machine where only the default subvolume makes problems but another subvolume can be snapshotted and the snapshot send. This machine uses kernel 3.14.15.
Please let me know what I can do to fix this.
Regards,

There was a similar issue in btrfs-progs 3.16 that was fixed in 3.16.1 by this commit:
https://git.kernel.org/cgit/linux/kernel/git/mason/btrfs-progs.git/commit/?id=6a47725a6fb8a463dd60611800222c7297195588
I'd do a quick btrfs --version just to make sure you're running the version you think you are. Otherwise, the output of mount might shed some light on why you're getting this.

Turns out I am still using btrfs-progs 3.16 :( Don't know where I came across the version 3.16.2 that I put in the subject. Gee, embarrassing.
Sorry for the noise. Hope 3.16.1 will be available in Debian testing soon.
