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.
