We observed the same thing with expansions. The OSDs will be very busy (with multiple threads per OSD) on housekeeping after the OMAP data has been moved to another OSD (and eating up all CPU power it can get). But even after that there is a lot of garbage left behind not gets cleaned up. At least not with regular housekeeping / online compaction. Manual compaction for clusters with a lot of OMAP data feels like a necessity (and ideally shouln't be). Gr.
