Hi, I found something else. 'ceph pg dump' shows PGs: - with zero or near zero objects count - with ~6,5k objects, size ~1,4G - with ~13k objects, size ~2,8G This can be a reason of wrong data distribution on OSD's? --- Regards Dominik 2014-01-30 Dominik Mostowiec <dominikmostowiec@xxxxxxxxx>: > Hi, > I have problem with data distribution. > Smallest disk usage 40% vs highest 82%. > All PGS: 6504. > Almost all data is in '.rgw.buckets' pool with pg_num 4800. > The best way to better data distribution is increese pg_num in this pool? > Is thre another way?
