> cinder-volume[8696]: segfault at 0 ip 00007fb8b937d70a sp 00007fb7b97f9bb0 error 4 in librbd.so.1.0.0[7fb8b9234000+52b000]

This is an error in an application (presumably a part of cinder) using librbd. Unfortunately the report lacks any information which could be used to debug the problem, such as

1) cluster configuration
   a) ceph -s
   b) the content of /etc/ceph/*
2) the exact steps to reproduce the error, preferably as a sequence of shell commands
3) core dump of the crashed process
