Hi Tim, This is the expected behaviour. Balance does not actually remember which chunks it had processed before it was paused, instead it uses a heuristic which is based on the amount of space used out of each chunk. As you have an almost full filesystem, all of your chunks, except for those ~7, are fully (or almost fully) used, and balance resume simply skips them. If you really want to balance everything (why?) you would have to run balance to completion, w/o pausing it.
