Hi
Because our block devices are fairly small and our containers don't write data inside them (and we hit issues with resizes being very slow) we have a static setup:
AUTO_EXTEND_POOL=False
The intention is to just create the lv as big as we can up front, because we don't need that space for anything else. We leave 2% for metadata.
However - we're running in to a problem, where our metadata volume is hitting 100% before out data volume gets close (sometimes, 60%). We're deploying kubernetes on these boxes, which garbage collects based on data usage not metadata usage, so we are often hitting the 100% and taking outÂ
boxes.
What I'm struggling to understand is how much metadata a docker image or docker container uses. If I can find that out I can figure out a good data:metadata ratio. Is there a way for me to discover this?
Or, as I suspect, am I missing something here?
Thanks
