Hi everyone, Please hold off on upgrading to this release. It triggers a bug in SimpleMessenger that causes threads for broken connections to spin, eating CPU. We're making sure we understand the root cause and preparing a fix. Thanks! sage On Wed, 7 Dec 2016, Abhishek L wrote:

This point release fixes several important bugs in RBD mirroring, RGW multi-site, CephFS, and RADOS.

We recommend that all v10.2.x users upgrade. Also note the following when upgrading from hammer

Upgrading from hammer ---------------------

When the last hammer OSD in a cluster containing jewel MONs is upgraded to jewel, as of 10.2.4 the jewel MONs will issue this warning: "all OSDs are running jewel or later but the 'require_jewel_osds' osdmap flag is not set" and change the cluster health status to HEALTH_WARN.

This is a signal for the admin to do "ceph osd set require_jewel_osds" - by doing this, the upgrade path is complete and no more pre-Jewel OSDs may be added to the cluster.
