@ -117,6 +117,10 @@ CephFS: Disallow delegating preallocated inode ranges to clients. Config
manager module. Users may choose between two new modes: ``upmap-read``, which
offers upmap and read optimization simultaneously, or ``read``, which may be used
to only optimize reads. For more detailed information see https://docs.ceph.com/en/latest/rados/operations/read-balancer/#online-optimization.
* CephFS: MDS log trimming is now driven by a separate thread which tries to
trim the log every second (`mds_log_trim_upkeep_interval` config). Also,
a couple of configs govern how much time the MDS spends in trimming its
logs. These configs are `mds_log_trim_threshold` and `mds_log_trim_decay_rate`.
