Hey guys, Regarding http://tracker.ceph.com/issues/38034A MBackfillReserve::RELEASE following by a MBackfillReserve::REQUEST from the primary are processed out of order at the backfill target.
This can be triggered by a preemption where the same PG immediately attempts to backfill again. What ensures that backfill node processes the messages from the primary in order? Is this a result of changes
in the messenger that were being tested? David
