<ul></ul><p>As it turned out, this was caused by small size of WAL (`bluestore block wal size`) and the fact I did not set `max_total_wal_size` properly. When I set both values to 1GB, the problem disappeared. Nevertheless I think that these values should not influence the performance of Ceph storage.</p> bluestore - Bug #48070: Wrong bluefs db usage value (doubled) returned by `perf dump` when option `bluestore_rocksdb_cf` is turned on.https://tracker.ceph.com/issues/48070?journal_id=1797692020-11-19T13:30:04ZKinga Karczewska
