and I have to repeat myself ... requirement for doing balance is situational and NOT needed to be run on time scheduled regular basis !! With quotas and without quotas it still moves unnecessarily huge amount on data and decreases the lifetime of drives and it also triggers unhealthy drives or drives in predictive failure state to die before they normally could !!! It's broken concept that everybody who uses btrfs just does it periodically by default .. This needs to be removed and not just fixed with tape and crutch by disabling quotas .. regards, dan
