I looked at a few more
containers. A couple have the ploop device and a couple do. I'm not
sure why. Most that do have the ploop devices have a bunch of stale
ones. For instance:<br>
<br>
# vzctl exec #### ls -l "/dev/ploop*"<br>
b-----x--- 1 root root 182, 300625 Jan 18 22:57 /dev/ploop18789p1<br>
b-----x--- 1 root root 182, 355073 Jan 18 22:57 /dev/ploop22192p1<br>

b-----x--- 1 root root 182, 897201 Jan 18 22:57 /dev/ploop56075p1<br>
<br>
The active one is pretty obvious (/dev/ploop46856p1). It doesn't seem
to be specific to node or kernel, the containers are split on the same
system.<br>
<br>
Have you filed a bug report?<br>

I can't speak as to how to
address the issue, but why do you consider it messed up? I logged in
to a few nodes and saw the same thing on all of them and I don't
remember this being any different in the past. The ploop device only
exists outside of the container (when mounted). Inside the container is
just a reference, no actual device exists.<br>
<br>
I don't know enough about the original issue, what are you trying to
accomplish with the ploop device inside the container?<br>
