v0.27 released

v0.27 released

[Sage Weil]

v0.27 is done!  This mostly bugfixes, cleanups, and incremental 
improvements.  Notably:

 * lots of cleanups in config file loading, handling, to make library 
behavior sane, warn on config file errors, etc.
 * osd: fix out of order ack bug
 * mount.ceph: uses kernel keys interface (when available) to pass secrets
 * osd, mon: use new syncfs() syscall where available
 * librados: compound object operation support
 * librbd: snapshot images no longer writeable
 * librbd: rollback to snapshot and other misc fixes
 * mds: journal replay cleanups, performance, bug fixes
 * mds: many clustered mds fixes (mostly with rename and recovery)
 * mds: standby-replay mode fixes
 * mds: robust lookuphash for better nfs reexport support
 * mon: bugfixes with mds takeover
 * obsync: synchronize object buckets between s3, directory, swift, rados
 * osd: misc recovery fixes
 * radosgw: dup bucket creation fixes
 * radosgw: many small protocol fixes

As part of the radosgw work we've created s3-tests.git, which includes a 
bunch of simple tests to verify implementations of the s3 protocol.  See

 * git://ceph.newdream.net/git/s3-tests.git
 * http://ceph.newdream.net/git/?p=s3-tests.git;a=summary

For v0.28 we're focusing on the OSD cluster, radosgw, and continuing with 
the MDS clustering fixes.  Sam and Josh are working on a refactor in the 
OSD peering code that will make peering more understandable, verifiable, 
and (we hope) less buggy.

In v0.27
When I run mkcephfs -c -a, I get

temp dir is /tmp/mkcephfs.Mts3TZhEwG
preparing monmap in /tmp/mkcephfs.Mts3TZhEwG/monmap
/usr/local/bin/monmaptool --create --clobber --add 0 --print
/tmp/mkcephfs.Mts3TZhEwG/monmap
/usr/local/bin/monmaptool: invalid ip:port '--print'
rm: cannot remove `/tmp/mkcephfs.Mts3TZhEwG/*': No such file or directory

and so I cannot start ceph up. But It was working till v0.26. Thanks

It seems you have a monitor defined without "mon addr" set in the
config file.

mkcephfs could use better error handling; I'll add that.

Im using ceph since a while an follow the mailinglist since more than a year.
In the same project as we use ceph, we also use a messaging api called
zeromq (http://www.zeromq.org/) for messaging between our other
components.
And i thought this might be a proper replacement for your messaging
implementation, which causes some trouble.

ZeroMQ was developed to speed up stock trading and is now widely used
in many high performance messaging applications.
It offers a lot of different messaging pattern implementations
(publish/subscribe, fanout, ..) as well as different transport
mechanisms (tcp, multicast (pgm), inprocess ..).
It has a brokerless design and has many language bindings, but is
entirely written in c/c++.
There is a very active community.

It is also very well documented: http://zguide.zeromq.org/page:all

I was thinking since some time to point the ceph development team to
this piece of code, now with your announcement of the 0.28 work i
decided to do so.

So if you want to spend some spare time to read through the basic
concepts, enjoy.

Greetings from Munich
