You can do
kill $pid
ceph osd down $osdid
(or even reverse the order, if the sequence is quick enough) to avoid
waiting for the failure detection delay. But if the OSDs are going down,
then the peering has to happen one way or another.
But exaclty this results in starting backfill immediatly. My idea was to
first mark the osd down so the mon knows about this fact. So no I/O is
stalled. And then reboot the whole host but exactly this does not work
like expected as backfilling is starting immediatly after setting the
osd to down ;-(
