There are also several major items backported to this release:

  • Standby ceph-mgr daemons now redirect requests to the active messenger, easing configuration of tools and humans that access the web dashboard, restful API, or other ceph-mgr module services.
  • The prometheus module has several significant updates and improvements.
  • The new balancer module enables automatic optimization of CRUSH weights to balance data across the cluster.
  • The ceph-volume tool has been updated to include support for BlueStore as well as FileStore. The only major missing ceph-volume feature is dm-crypt support.

Two things with this bullet point:

  1. the line is very long - can it be wrapped/indented to fit into 80 characters like the lines in the intro above?
  2. the formulation "easing configuration of tools and humans . . ." strikes me as odd? Maybe just drop "and humans"?

* The prometheus module has several significant updates and improvements.
* The new balancer module enables automatic optimization of CRUSH weights to balance data across the cluster.
* The ceph-volume tool has been updated to include support for BlueStore as well as FileStore. The only major missing ceph-volume feature is dm-crypt support.
* RGW's dynamic bucket index resharding is disabled in multisite environments.

Here, as a reader, I'm missing an explanation of why it was disabled?

as FileStore. The only major missing ceph-volume feature is dm-crypt support.
* RGW's dynamic bucket index resharding is disabled in multisite environments,
as it can cause inconsistencies in replication of bucket indexes to remote
