And the other minute I started my fairly destructive testing, 0.52 never
ever failed on that. And then a loop started with

leading to high CPU-load on node2 ( IP 10.0.0.11). The destructive part
happens on node3 ( IP 10.0.0.12).
Procedure is as always just kill some OSDs and start over again...
Happened now twice, so I would call it reproducable ;)
Kind regards,

Another development release of Ceph is ready, v0.53. We are getting
pretty
close to what will be frozen for the next stable release (bobtail),
so if
you would like a preview, give this one a go. Notable changes include:
* librbd: image locking
* rbd: fix list command when more than 1024 (format 2) images
* osd: backfill reservation framework (to avoid flooding new osds
with
backfill data)
* osd, mon: honor new 'nobackfill' and 'norecover' osdmap flags
* osd: new 'deep scrub' will compare object content across replicas
(once
per week by default)
* osd: crush performance improvements
* osd: some performance improvements related to request queuing
* osd: capability syntax improvements, bug fixes
* osd: misc recovery fixes
* osd: fix memory leak on certain error paths
* osd: default journal size to 1 GB
* crush: default root of tree type is now 'root' instead of 'pool'
(to
avoid confusiong wrt rados pools)
* ceph-fuse: fix handling for .. in root directory
* librados: some locking fixes
* mon: some election bug fixes
* mon: some additional on-disk metadata to facilitate future mon
changes
(post-bobtail)
* mon: throttle osd flapping based on osd history (limits osdmap
"thrashing" on overloaded or unhappy clusters)
* mon: new 'osd crush create-or-move ...' command
* radosgw: fix copy-object vs attributes
* radosgw: fix bug in bucket stat updates
* mds: fix ino release on abort session close, relative getattr
path, mds
shutdown, other misc items
* upstart: stop jobs on shutdown
* common: thread pool sizes can now be adjusted at runtime
* build fixes for Fedora 18, CentOS/RHEL 6
The big items are locking support in RBD, and OSD improvements like
deep
scrub (which verify object data across replicas) and backfill
reservations
(which limit load on expanding clusters). And a huge swath of bugfixes
and
cleanups, many due to feeding the code through scan.coverity.com (they
offer free static code analysis for open source projects).
v0.54 is now frozen, and will include many deployment-related fixes
(including a new ceph-deploy tool to replace mkcephfs), more
bugfixes for
libcephfs, ceph-fuse, and the MDS, and the fruits of some performance
work
on the OSD.
You can get v0.53 from the usual locations:
* Git at git://github.com/ceph/ceph.git
* Tarball at http://ceph.com/download/ceph-0.53.tar.gz
* For Debian/Ubuntu packages, see
http://ceph.com/docs/master/install/debian
* For RPMs, see http://ceph.com/docs/master/install/rpm
