It seems like a low hanging fruit to fix? There must be a reason why the developers have not made a prioritized order of backfilling PGs. Or maybe the prioritization is something else than available space? The answer remains unanswered, as well as if my suggested approach/script would work or not? Summer vacation?

You are absolutely right there, just wanted to chip in with my experiences of "it nags at me but it will still work out" so other people finding these mails later on can feel a bit relieved at knowing that a few toofull warnings aren't a major disaster and that it sometimes happens, because ceph looks for all possible moves, even those who will run late in the rebalancing. -- May the most significant bit of your life be positive. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
