thanks to dmick, he helped to look at the involved test nodes, the partition tables of the reported devices are zeroed, but that should not be fatal.
in the case of mira077, the osd.3 was up and running before ceph-objectstore-tools list pg:
ceph-objectstore-tool --data-path /var/lib/ceph/osd/ceph-3 --journal-path /var/lib/ceph/osd/ceph-3/journal --log-file=/var/log/ceph/objectstore_tool.\\$pid.log --op list-pgs'
and failed with
2017-07-20T09:29:14.829 INFO:teuthology.orchestra.run.mira077.stderr:Mount failed with '(5) Input/output error'
and another interesting thing is that teuthology reports I/O error also
2017-07-20T09:29:14.832 ERROR:teuthology:Uncaught exception (Hub)
