Each pool gets its own set of PGs (Placement Groups). An OSD that manages too many PGs will use a lot of RAM. What is "too many" is debatable, and really up to benchmarks, but considering we recommend about 100 PGs/OSD as a starting point, you probably don't want to go two orders of magnitude above that. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
