You can reduce pg count per OSD for example, it scales down well enough. OSD memory footprint (during recovery or normal operations) depends of number of objects, e.g. commited data and total count of PGs per OSD. Because deleting some data is not an option, I may suggest only one remaining way :) I had raised related question a long ago, it was about post-recovery memory footprint patterns - OSD shrinks memory usage after successful recovery in a relatively long period, up to some days and by couple of fast 'leaps'. Heap has nothing to do with this bug I had not profiled the daemon itself yet. > _______________________________________________ > ceph-users mailing list > [email protected] > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com > _______________________________________________ ceph-users mailing list [email protected] http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
