I am attempting to resize a ploop file system but receive an error.  Here
is the command and the output:

This is while the container is down:

root at cluster-01:/var/log# vzctl set 15000 --diskspace 5G --save

This is while the container is started:

When I first tried to resize the ploop device, I used the information on
this site: http://openvz.org/Ploop/readme

This site instructed me to resize/balloon the file system
ploop grow -s 10g -d /dev/ploop38961

Not sure how to undo the damage I've done.

I did the same resize on another container without any issues using vzctl.
Not sure what is special about this container.

Any help is appreciated.

Thanks,
Axton Grams
