This might be the root of our problems.  We didn't mark the parent OSD as 
"lost" before we removed it.  Now ceph won't let us mark it as lost (and it is 
no longer in the OSD tree):

djakubiec@dev:~$ ceph osd lost 8 --yes-i-really-mean-it
osd.8 is not down or doesn't exist


djakubiec@dev:~$ ceph osd tree

 7  7.27489         osd.7        up  1.00000          1.00000

BUT, even though OSD 8 no longer exists I see still lots of references to OSD 8 
in various dumps and query's.

Interestingly do still see weird entries in the CRUSH map (should I do 
something about these?):

# devices
device 0 device0
device 1 osd.1
device 2 osd.2
device 3 osd.3
device 4 osd.4
device 5 osd.5
device 6 osd.6
device 7 osd.7
device 8 device8
device 9 osd.9

I then tried on all 80 incomplete PGs:

        ceph pg force_create_pg <pgid>

The 80 PGs moved to "creating" for a few minutes but then all went back to 
"incomplete".

Is there some way to force individual PGs to be marked as "lost"?

Thanks!
