Another three months have gone by, and the next stable release of Ceph is
ready: Dumpling! Thank you to everyone who has contributed to this
release!
This release focuses on a few major themes since v0.61 (Cuttlefish):
* rgw: multi-site, multi-datacenter support for S3/Swift object storage
* new RESTful API endpoint for administering the cluster, based on a new
and improved management API and updated CLI
* mon: stability and performance
* osd: stability performance
* cephfs: open-by-ino support (for improved NFS reexport)
* improved support for Red Hat platforms
* use of the Intel CRC32c instruction when available
As with previous stable releases, you can upgrade from previous versions
of Ceph without taking the entire cluster online, as long as a few simple
guidelines are followed.
* For Dumpling, we have tested upgrades from both Bobtail and Cuttlefish.
If you are running Argonaut, please upgrade to Bobtail and then to
Dumpling.
* Please upgrade daemons/hosts in the following order:
1. Upgrade ceph-common on all nodes that will use the command line ceph
utility.
2. Upgrade all monitors (upgrade ceph package, restart ceph-mon
daemons). This can happen one daemon or host at a time. Note that
because cuttlefish and dumpling monitors cant talk to each other,
all monitors should be upgraded in relatively short succession to
minimize the risk that an untimely failure will reduce availability.
3. Upgrade all osds (upgrade ceph package, restart ceph-osd daemons).
This can happen one daemon or host at a time.
4. Upgrade radosgw (upgrade radosgw package, restart radosgw daemons).
There are several small compatibility changes between Cuttlefish and
Dumpling, particularly with the CLI interface. Please see the complete
release notes for a summary of the changes since v0.66 and v0.61
Cuttlefish, and other possible issues that should be considered before
upgrading:
