Hi,

I just performed a minor ceph upgrade on my ubuntu 14.04 cluster from ceph
version to0.94.6-1trusty  to  0.94.7-1trusty.   Upon restarting the OSDs, I
receive the error message:

2016-06-01 12:17:49.219512 7f64a70ea8c0  0 monclient: wait_auth_rotating

eventually the OSD fails to start.    Oddly, this affects only some of the
OSDs on this host.
On the mon host, there is a warning:

How do I clear these up after the upgrade?    All of the filesystems on the
OSDs are mounted and the keyrings are there......

Thanks,
Jeff
