A release candidate for 0.72 emperor is ready! This candidate squashes the last of the blocker bugs and includes all of the functionality that will be present in the final 0.72. Looking back to dumpling, overall I think we are also in much better shape than before: better overall stability from our testing and much broader test coverage. Please test! Emperor will include several key improvements over dumpling: - improved crc32c performance (intel optimizations, caching) - mon: friendly warnings when pg counts are out of whack - mon: per-pool performance statistics - mon: stability and cpu utilization improvements - osd: improved interaction with backend file systems (lower latency) - osd, librados: new copy primitives (to support in-progress tiering work) - osd: lots of internal clean and refactoring (to support erasure coding) - rgw: bucket quotas - rgw: performance improvements - rgw: validate S3 tokens against keystone - mds: many many bug fixes and improvements (mostly from Yan, Zheng of Intel) - librados: new class and client example code The draft release notes can be found here: - http://ceph.com/docs/master/release-notes/ You can get the emperor packages from the 'testing' rpm and deb locations: - http://ceph.com/debian-testing - http://ceph.com/rpm-testing We will also be putting them in the stable emperor locations shortly (e.g., /debian-emperor). If you anticipate moving from dumpling to emperor, please try this release on any test environment you have available. If you are still running cuttlefish or bobtail, upgrade to dumpling already! sage _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
