Thank you for that info Anthony, I just wanted to know the expected behavior. In that same vein, when I use btrfs sub list it lists all subvols regardless of whether or not it is given a path argument. Is this current behavior as well. Thanks again.

Good afternoon btrfs,
I have been having issues with snapshots not reading the whole file tree below them. I have installed new btrfs-progs from

git://git.darksatanic.net/repo/btrfs-progs-unstable.git

made and installed them.  My tree is:  /Btrfs |
                                              |__ nfs1 |
                                                       |__ data |
|__ sites | |__ 00xx | |__ email@address

If I use btrfsctl -s (btrfs sub snapshot isn't working) snappath-name /btrfs/nfs1 I get a mountable snapshot of nfs1 but data is all that I can see below it. If I btrfsctl -s snappath-name /btrfs/nfs1/data/sites/0000 I can mount /0000 and get a full list of email@address accounts but none of the files below them. I should have stated earlier, everything down to and including /email@address are subvolumes. Below /email@address directories and files were rsync'd into the subvol from an nfs mount. Finally if I snapshot /email@address I have access to all directories and files below them. Because of this I believe that the issue is with snapshots of subvolumes. I thought I just couldn't see subvols above the snapshot level and was able to see subvols below. Am I confused or is this a real problem. I am using kernel 3.1.0-rc4 and will be happy to trace anything you need if you can tell me how to get what you need. Thanks for your help.
Jim

yaarg -- resend w/list included -- changed clients recently (tbird) and cant figure out how to default to replay-all ...

i believe this is expected behavior as of now -- there are a couple threads mentioning `recursive snapshotting`, check those out. AFAIK a snapshot will not traverse beyond it's own boundaries.
