Thanks!
So to sum up, I'd best:
* set the noout flag
* stop the OSDs one by one
* shut down the physical node
* jank the OSD drives to prevent ceph-disk(8) from automaticly
activating at boot time
* do my maintainance
* start the physical node
* reseat and activate the OSD drives one by one
* unset the noout flag
