I guess we will wait 3-4 days for cluster recovery to finish and I will update you if something happens once it's HEALTH_OK.
Is there a way to force epoch/osdmap trimming on rebalancing cluster?
I would use https://github.com/cernceph/ceph-scripts/blob/master/tools/upmap/upmap-remap... A pass or two of that will enter upmaps to obviate the current backfill. If you also temporarily disable the balancer you should very quickly get to a point with no backfill_wait. Then after the trimming and the dust settles you should re-enable the balancer to finish.
Afaik there no way to do it. It would be nice if we had such ability. It's not the first time we have this class of issues (big mon DBs). I would consider it a major flaw of the ceph. It cannot get healthier until it's not in a perfectly healthy state.
