v0.65 released

Our next development release v0.65 is out, with a few big changes.  First and foremost, this release includes a complete revamp of the architecture for the command line interface in order to lay the groundwork for our ongoing REST management API work.  The ‘ceph’ command line tool is now a thin python wrapper around librados.  Note that this set of changes includes several small incompatible changes in the interface that tools or scripts utilizing the CLI should be aware of; these are detailed in the complete release notes.

Other notable changes:

  • mon, ceph: huge revamp of CLI and internal admin API. (Dan Mick)
  • mon: new capability syntax
  • osd: do not use fadvise(DONTNEED) on XFS (data corruption on power cycle)
  • osd: recovery and peering performance improvements
  • osd: new writeback throttling (for less bursty write performance) (Sam Just)
  • osd: ping/heartbeat on public and private interfaces
  • osd: avoid osd flapping from asymmetric network failure
  • osd: re-use partially deleted PG contents when present (Sam Just)
  • osd: break blacklisted client watches (David Zafman)
  • mon: many stability fixes (Joao Luis)
  • mon, osd: many memory leaks fixed
  • mds: misc stability fixes (Yan, Zheng, Greg Farnum)
  • mds: many backpointer improvements (Yan, Zheng)
  • mds: new robust open-by-ino support (Yan, Zheng)
  • ceph-fuse, libcephfs: fix a few caps revocation bugs
  • librados: new calls to administer the cluster
  • librbd: locking tests (Josh Durgin)
  • ceph-disk: improved handling of odd device names
  • ceph-disk: many fixes for RHEL/CentOS, Fedora, wheezy
  • many many fixes from static code analysis (Danny Al-Gaaf)
  • daemons: create /var/run/ceph as needed

We have one more sprint to go before the Dumpling feature freeze.  Big items include monitor performance and stability improvements and multi-site and disaster recovery features for radosgw.  Lots of radosgw has already appeard in rgw-next but these changes will not land until v0.67.
