v0.67 Dumpling released

v0.67 Dumpling released

[Sage Weil]

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:

Dumpling is the second Ceph release on our new three-month stable release 
cycle.  We are very pleased to have pulled everything together on 
schedule.  The next stable release, which will be code-named Emperor, is 
slated for three months from now (beginning of November).

 * Git at git://github.com/ceph/ceph.git
 * Tarball at http://ceph.com/download/ceph-0.67.tar.gz

Seem there is a new dependency in the ceph-common debian package: python-ceph

Is that really required (previous release does not depend on that)?

Sure is - the 'ceph' command line tool is now written in python and
uses python-ceph to interact with ceph daemons.

It is.  The new 'ceph' CLI utility is written in python and uses the 
librados python bindings to communicate with the cluster.

Hi lists,

in this release I see that the ceph command is not compatible with 
python 3. The changes were not all trivial so I gave up, but for those 
using gentoo, I made my ceph git repository available here with an 
ebuild that forces the python version to 2.6 ou 2.7 :

git clone https://git.isi.nc/cloud/cloud-overlay.git

I upgraded from cuttlefish without any problem so good job 
ceph-contributors :)

Have a nice day.
