Another sprint and another release! This one is delayed a day or two due to power issues in our data center. The most exciting bit here is a big refactor in the monitor that has finally landed (thanks go to Joao Luis), but there is lots of other good stuff to go around: * mon: rearchitected to utilize single instance of paxos and a key/value store (Joao Luis) * mon: new 'ceph df [detail]' command * osd: support for improved hashing of PGs across OSDs via HASHPSPOOL pool flag and feature * osd: refactored watch/notify infrastructure (fixes protocol, removes many bugs) (Sam Just) * osd, librados: ability to list watchers (David Zafman) * osd, librados: new listsnaps command (David Zafman) * osd: trim log more aggressively, avoid appearance of leak memory * osd: misc split fixes * osd: a few journaling bug fixes * osd: connection handling bug fixes * rbd: avoid FIEMAP when importing from file (it can be buggy) * librados: fix linger bugs (Josh Durgin) * librbd: fixed flatten deadlock (Josh Durgin) * rgw: fixed >4MB range requests (Jan Harkes) * rgw: fix log rotation * mds: allow xattrs on root * ceph-fuse: fix statfs(2) reporting * msgr: optionally tune TCP buffer size to avoid throughput collapse (Jim Schutt) * consume less memory for logging by default * always use system leveldb (Gary Lowell) WARNING: We noticed the librados headers are broken as the build was going out, and the fix just missed the build. We'll do a point release if anyone needs it. When upgrading, try to avoid leaving mixed monitor versions for long periods of time; see the release notes for more details: http://ceph.com/docs/master/release-notes/#v0-59 In other news, the ceph-cookbooks for Chef just got a long-overdue update. If you are a Chef user, please take a look at the updated repo on github and let us know what you think (or better yet start sending your pull requests our way): http://github.com/ceph/ceph-cookbooks I should also mention that, although you don't see much action here, Caleb and Yehuda are hard at work on the multi-site, disaster recovery, and API features for radosgw. You can get v0.59 from the usual places: * Git at git://github.com/ceph/ceph.git * Tarball at http://ceph.com/download/ceph-0.59.tar.gz * For Debian/Ubuntu packages, see http://ceph.com/docs/master/install/debian * For RPMs, see http://ceph.com/docs/master/install/rpm _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
