We're also in the process of updating Ceph Hammer from 0.94.6 to 0.94.9
I have a candidate build out for 0.94.9 [1] which might need to go out ASAP.
We've been having issues where 0.94.6 is hanging and failing in our CI under certain circumstances whereas I am unable to reproduce the problem on 0.94.9. I'm not able to put my finger on what the exact problem is - the problem reproduces on ci.centos.org jobs consistently where it does not elsewhere. This might be happening since CentOS 7.3 is out ? Maybe something related to that.
To get 0.94.9 to build, install and run, I needed to tag the following that were missing from ceph-hammer-candidate: - libbabeltrace [2] (would otherwise fail to build from source) - lttng-ust [3] (would otherwise fail to build from source) - userspace-rcu [4] (dependency for lttng-ust for liburcu-cds.so && liburcu-bp.so)
For the record, here's the spec file update for 0.94.6 to 0.94.9 [5].
Here's a sample .repo file to test it out: --- [centos-ceph-hammer-candidate] name=CentOS-7 - Ceph Hammer Candidate baseurl=http://cbs.centos.org/repos/storage7-ceph-hammer-candidate/x86_64/os/ gpgcheck=0 priority=1 enabled=1 ---
I've successfully tested 0.94.9 in an OpenStack use case (backing Nova, Glance, Cinder and Gnocchi) without problems but I'd like to hear back from at least someone else.
Thanks and let me know if you have any questions,
