Hi, All osds in the dev cluster died shortly after upgrade (packet-only, i.e. binary upgrade, even without restart running processes), please see attached file. Was: 0.55.1-356-g850d1d5 Upgraded to: 0.56 tag The only one difference is a version of the gcc corresponding libstdc++ - 4.6 on the buildhost and 4.7 on the cluster. Of course I may do a rollback and problem will eliminate with high probability, but seems there should be some fix. Also I have something simular in the the testing env days ago - packet upgrade inside 0.55 killed all _windows_ guests_ and one of tens of linux guests running above rbd. Unfortunately I have no debug sessions at this moment and I have only tail of the log from qemu: terminate called after throwing an instance of 'ceph::buffer::end_of_buffer' what(): buffer::end_of_buffer I`m blaming ldconfig action from librbd because nothing else `ll cause such case of destroy on the running processes - may be I`m wrong. thanks! WBR, Andrey
