[Users] Fragmentation on VZ7

Howdy,

I'm running a graphing container on VZ7. Specifically it's running
carbon-cache with metrics coming in every minute for a total of 46G of
stats spread out over 193349 files. This disk space usage of this
containers ploop container is regularly blowing up.

Today, I ran the following command:

prl_disk_tool compact --hdd /vz/private/101/root.hdd

This freed up 172GB of disk space.

How do I prevent this kind of fragmentation from building up? Am I
expected to compact the ploop images on a regular basis?

Thanks,
Chris
