I tagged and uploaded v0.28 a week ago but forgot to blog and email about it. That may be just as well, as there were a number of issues that got fixed last week. I’ll separate out the main items. Changes for v0.28: osd: peering code refactor osd: long object name support osd: removed fragile […]
We’ve released v0.27.1. This includes a few bugfixes for v0.27, including mds: misc journaling and replay bugs mds: fixed –reset-journal cfuse: fixed device major/minor values conf: less noise to stdout osd: fixed file descriptor leak from fiemap operation In short, nothing terribly earth shattering. v0.28 is about a week away, and will include significant changes […]
v0.27 is done! This mostly bugfixes, cleanups, and incremental improvements. Notably: * lots of cleanups in config file loading, handling, to make library behavior sane, warn on config file errors, etc. * osd: fix out of order ack bug * mount.ceph: uses kernel keys interface (when available) to pass secrets * osd, mon: use new […]

Are you a Linux kernel programmer interested in a job working on the Ceph distributed file system or btrfs? Are you a C/C++ developer interested in building scalable, fault tolerant and high performance distributed systems? Are you an experienced QA engineer with a storage or distributed system background? DreamHost is hiring Ceph engineers for our […]
This a bugfix release. If you’re using librados or librbd, please upgrade, as there are some small API fixes. If not, there isn’t anything too critical here aside from some OSD recovery corner cases. * librados: some size_t -> uint64_t type conversions to support large objects * librbd: lots of size_t -> uint64_t conversions for […]
We’ve just tagged the v0.25 release. Most of the work here is in the OSD cluster, a new librbd library (refactoring existing RBD infrastructure), and a librados API refresh. * osd: fix map churn while peering * osd: “watch/notify” framework for RBD synchronization * osd: ability to read from closest replica * osd: many bug […]
We’ve released v0.24.3 with more bug fixes, including one that loses data in certain cases when OSDs restart during recovery. It’s pretty much all OSD stuff, which is where we’re focusing our testing efforts currently. osd: misc crashes, slowness osd: fix bug that loses backlog (and potentially data) osd: scrub fixes osd: snap_trimmer fixes mds: fix […]
I’ll be giving a talk at SCALE 9x targeted toward system administrators and users. It’ll be Sunday, February 27th at 4:30pm in the Century AB room. Hope to see you there!
UPDATE: Here are the slides, as ODF and PDF.
