Release 2016_009 (2016-03-09)

Impact

• All Cluster daemons will be restarted, slowly and carefully, to activate the new release and configuration. We do not expect noticable impact.

Packages

• Update Ceph: 0.94.5 -> 0.94.6

• Fix box hashes (#20488)

Configuration

• We are ignoring the security update for ipython GLSA 201512-02 as we are not affected by the issue.

• Adjust Ceph options to make maintenance activities like scrubbing and snapshot trimming less impactful.

• Switch Ceph to “jemalloc” allocator for improved latency.
