memory usage grows as storage volume grows #59

I hope this is still alive and running, regardless I'm seeing a strange issue. Basically I was switching from old nfs storage to this new storage. I mounted the pvc as a volume called backup on the container. Then just did an rsync from old directory to the new when the container crashed OOM? At first I was very suprised and thought it had to be something to do with the files? I tried many many tests after that. Tried spinning up a brand new container. Nothing on it. Add a pvc which is 8g. Then copied a 66mg file onto the container as a tar.gz. Its just a really big text file. Extract the file which becomes 1.5g. And as you imagine memory for the container spikes with the new data? Screen Shot 2020-06-08 at 7 11 18 PM

Is there something I'm missing? Please let me know if there is anything I can provide to help narrow this down.
