I have read many times the post "incomplete pgs, oh my"
I think my case is different.
The broken disk is completely broken.
So how can I simply mark incomplete pgs as complete?
Should I stop ceph before?

Hi,
if you need fast access to your remaining data you can use
ceph-objectstore-tool to mark those PGs as complete, however this will
irreversibly lose the missing data.
If you understand the risks, this procedure is pretty good explained here:
http://ceph.com/community/incomplete-pgs-oh-my/
Since this article was written, ceph-objectstore-tool gained a feature
that was not available at that time, that is "--op mark-complete". I
think it will be necessary in your case to call --op mark-complete after
you import the PG to temporary OSD (between steps 12 and 13).
