If anybody has 5 minutes could they just clarify a couple of things
for me
1. onode count, should this be equal to the number of objects stored
on the OSD?
Through reading several posts, there seems to be a general indication
that this is the case, but looking at my OSD's the maths don't
work.
onode_count is the number of onodes in the cache, not the total number
of onodes at an OSD.
Hence the difference...
Ok, thanks, that makes sense. I assume there isn't actually a counter which gives you the total number of objects on an OSD then?
IIRC "bin/ceph daemon osd.1 calc_objectstore_db_histogram" might report
what you need, see "num_onodes" field in the report..
