We’re pleased to annouce the release of Ceph v0.48, code-named “argonaut.” This release will be the basis of our first long-term stable branch. Although we will continue to make releases every 3-4 weeks, this stable release will be maintained with bug fixes and select non-destabilizing feature additions for much longer than that. Argonaut is recommended for production users of rados and librados, rbd and librbd, and radosgw.
The upgrade to v0.48 argonaut from previous versions includes a disk-format upgrade. Please note:
The highlights for this release include:
The new default keyring locations mean that when enabling authentication (‘auth supported = cephx’), keyring locations do not need to be specified if the keyring file is located inside the daemon’s data directory (/var/lib/ceph/$type/ceph-$id by default).
There is also a lot of librbd code in this release that is laying the groundwork for the upcoming layering functionality, but is not actually used. Likewise, the upstart support is still incomplete and not recommended; we will backport that functionality later if it turns out to be non-disruptive.
For more information, please see the complete release notes.
The current focus for upcoming development releases is on radosgw stability, RBD stability, and RBD layering. There is also ongoing ‘devops’ work on integration with management and provisioning tools like upstart, Chef, Juju, and Crowbar. A major refactor of the OSD code is about to be merged which will improve performance and scalability, and our testing coverage continues to improve.
