We will have a maintenance stop soon so I guess updating the kernel will be top priority but I'm not sure we can do the 3 kernel series...

Not quite sure I follow, we already have 0.72-1

[root@compute-1-1 ~]# rpm -qa | grep ceph
ceph-0.72.1-0.el6.x86_64
libcephfs1-0.72.1-0.el6.x86_64
ceph-fuse-0.72.1-0.el6.x86_64
python-ceph-0.72.1-0.el6.x86_64


Does this mean we are having some other bug?

Cheers,
