    v0.62 released

    This is the first release after cuttlefish.

    Behold, another Bobtail update!  This one serves three main purposes: it fixes a small issue with monitor features that is important when upgrading from argonaut -> bobtail -> cuttlefish, it backports many changes to the ceph-disk helper scripts that allow bobtail clusters to be deployed with the new ceph-deploy tool or our chef cookbooks, and it […]

    v0.56.4 released

    There have been several important fixes that we’ve backported to bobtail that users are hitting in the wild.  Most notably, there was a problem with pool names with – and _ that OpenStack users were hitting, and memory usage by ceph-osd and other daemons due to the trimming of in-memory logs.  This and more is […]

    Ceph Settles in to Aggressive Release Cadence

    Since its inception, Ceph has always had a fast-paced rolling release tempo. However, with the amount of adoption that Ceph has had over the last year (including continued integration work with several other open source projects), we wanted to move to a more reliable, and predictable, release schedule. The release schedule can be divided into […]
