There is a config option "mon osd min up ratio" (defaults to 0.3) - and
if too many OSDs are down, the monitors will not mark further OSDs
down. Perhaps that's the culprit here?

If you can't ping a host, that only means you cannot ping it.

Subject: Ceph - incorrect output of ceph osd tree
Hi,
Why is ceph osd tree reports that osd.4 is up when the server on which
osd.4 is running is actually down ??
Any help will be appreciated
