v0.94.1 Hammer released

This bug fix release fixes a few critical issues with CRUSH. The most important addresses a bug in feature bit enforcement that may prevent pre-hammer clients from communicating with the cluster during an upgrade. This only manifests in some cases (for example, when the ‘rack’ type is in use in the CRUSH map, and possibly […]

v0.94 Hammer released

This major release is expected to form the basis of the next long-term stable series. It is intended to supersede v0.80.x Firefly. Highlights since Giant include: RADOS Performance: a range of improvements have been made in the OSD and client-side librados code that improve the throughput on flash backends and improve parallelism and scaling on […]

v0.80.9 Firefly released

This is a bugfix release for firefly. It fixes a performance regression in librbd, an important CRUSH misbehavior (see below), and several RGW bugs. We have also backported support for flock/fcntl locks to ceph-fuse and libcephfs. We recommend that all Firefly users upgrade. For more detailed information, see the complete changelog. ADJUSTING CRUSH MAPS This point release fixes […]

v0.93 Hammer release candidate released

This is the first release candidate for Hammer, and includes all of the features that will be present in the final release. We welcome and encourage any and all testing in non-production clusters to identify any problems with functionality, stability, or performance before the final Hammer release. We suggest some caution in one area: librbd. […]

v0.87.1 Giant released

This is the first (and possibly final) point release for Giant. Our focus on stability fixes will be directed towards Hammer and Firefly. We recommend that all v0.87 Giant users upgrade to this release. UPGRADING Due to a change in the Linux kernel version 3.18 and the limits of the FUSE interface, ceph-fuse needs be […]

v0.92 released

This is the second-to-last chunk of new stuff before Hammer. Big items include additional checksums on OSD objects, proxied reads in the cache tier, image locking in RBD, optimized OSD Transaction and replication messages, and a big pile of RGW and MDS bug fixes. UPGRADING The experimental ‘keyvaluestore-dev’ OSD backend has been renamed ‘keyvaluestore’ (for […]

v0.91 released

We are quickly approaching the Hammer feature freeze but have a few more dev releases to go before we get there. The headline items are subtree-based quota support in CephFS (ceph-fuse/libcephfs client support only for now), a rewrite of the watch/notify librados API used by RBD and RGW, OSDMap checksums to ensure that maps are […]

v0.80.8 Firefly released

This is a long-awaited bugfix release for firefly. It several imporant (but relatively rare) OSD peering fixes, performance issues when snapshots are trimmed, several RGW fixes, a paxos corner case fix, and some packaging updates. We recommend that all users for v0.80.x firefly upgrade when it is convenient to do so. NOTABLE CHANGES

v0.90 released

This is the last development release before Christmas. There are some API cleanups for librados and librbd, and lots of bug fixes across the board for the OSD, MDS, RGW, and CRUSH. The OSD also gets support for discard (potentially helpful on SSDs, although it is off by default), and there are several improvements to […]

v0.88 released

This is the first development release after Giant. The two main features merged this round are the new AsyncMessenger (an alternative implementation of the network layer) from Haomai Wang at UnitedStack, and support for POSIX file locks in ceph-fuse and libcephfs from Yan, Zheng. There is also a big pile of smaller items that re […]
