We urge all v0.61.1 users to upgrade to avoid filling the monitor data disks. mon: fix conversion of stores with duplicated GV values mon: disable […]

    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 […]
