The usage for the radosgw-admin + command and the 'rgw zone root pool' config optoins have changed + accordingly. + +* rbd progress indicators now go to standard error instead of standard + out. (You can disable progress with --no-progress.) + +* The 'rbd resize ...' command now requires the --allow-shrink option + when resizing to a smaller size. Expanding images to a larger size + is unchanged. + +* Please review the changes going back to 0.56.4 if you are upgrading + all the way from bobtail. + +* The old 'ceph stop_cluster' command has been removed. + +* The sysvinit script now uses the ceph.conf file on the remote host + when starting remote daemons via the '-a' option. Note that if '-a' + is used in conjuction with '-c path', the path must also be present + on the remote host (it is not copied to a temporary file, as it was + previously). + +* The monitor is using a completely new storage strategy and + intra-cluster protocol. This means that cuttlefish and bobtail + monitors do not talk to each other. When you upgrade each one, it + will convert its local data store to the new format. Once you + upgrade a majority, the quorum will be formed using the new protocol + and the old monitors will be blocked out until they too get + upgraded. For this reason, we recommend not running a mixed-version + cluster for very long. + +* ceph-mon now requires the creation of its data directory prior to + --mkfs, similarly to what happens on ceph-osd. This directory is no + longer automatically created, and custom scripts should be adjusted to + reflect just that. + +* The monitor now enforces that MDS names be unique. If you have + multiple daemons start with with the same id (e.g., ``mds.a``) the + second one will implicitly mark the first as failed. This makes + things less confusing and makes a daemon restart faster (we no + longer wait for the stopped daemon to time out) but existing + multi-mds configurations may need to be adjusted accordingly to give + daemons unique names. + +* The 'ceph osd pool delete ' and 'rados rmpool ' + now have safety interlocks with loud warnings that make you confirm + pool removal. Any scripts curenty rely on these functions zapping + data without confirmation need to be adjusted accordingly. + + +Notable Changes from v0.60 +~~~~~~~~~~~~~~~~~~~~~~~~~~ * rbd: incremental backups
