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).
