hi
i was looking for a way to list all snapshots*.
then i discovered this:
mkdir ./.snap/test
then i found this:
./.snap/test
./subdir/.snap/_test_1099511630280
the subdir/.snap/_test_1099511630280 vanishes if i delete the ./.snap/
test.

This is expected, because subdir's contents are contained by the 'test'
snap, and we want the .snap/ dir to show you all snaps that contain
copies of the current directory. The name is mangled
(_$snap_$snap_root_ino) to avoid collisions with the current directory's
snap namespace. Snaps beginning with _ are disallowed.

find ./ -type d -print0 | \
xargs -0 -I% -n1 find %/.snap -mindepth 1 -maxdepth 1 \
\( ! -name "_*" \)
should do it, I think.

thanks for the explanation! i've created
http://ceph.newdream.net/wiki/Snapshots
for future reference.

Hi all,
It would be sweet to get shadow copy for Samba to work with Ceph
snapshots. This blog entry (for ZFS) might be a good start if anyone is
interested in experimenting and documenting (for Ceph)!
http://www.edplese.com/blog/2009/12/02/samba-shadow_copy2-enhancements/
One difference seem to be that Samba is expecting the snapshots to be per
volume and not per directory, but I havn't had time to look into it
further.
