[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
