Ceph » bluestore

While maybe not directly triggered by ceph-volume, the following error is displayed on osd creation. OSD is still created and starts.

 stderr: 2017-11-30 15:30:48.794603 7f3555cf6e00 -1 bluestore(/var/lib/ceph/osd/ceph-17//block) _read_bdev_label unable to decode label at offset 102: buffer::malformed_input: void bluestore_bdev_label_t::decode(ceph::buffer::list::iterator&) decode past end of struct encoding
