> What's the issue with adding all osd with noout and norebalance and once all of them up, unset rebalance? In sufficiently small and/or fast clusters, this is probably fine. For other clusters, the reasons that one may not want to do this are outlined at the start of the pgremapper readme: https://github.com/digitalocean/pgremapper To give a sense of scale, for some of our clusters, we measure post-augment backfill time in days to weeks. We're very interested in methods that can be used to tightly control backfill in these cases, which is why we built pgremapper.
