There was a very recent thread discussing PG calculations, and it made me doubt my cluster setup. So, Inktank, please provide some clarification.
I followed the documentation, and interpreted that documentation to mean that PG and PGP calculation was based upon a per-pool calculation. The recent discussion introduced a slightly different formula adding in the total number of pools: # OSD * 100 / 3 vs. # OSD's * 100 / (3 * # pools) My current cluster has 24 OSD's, replica size of 3, and the standard three pools, RBD, DATA, and METADATA. My current total PG's is 3072, which by the second formula is way too many. So, do I have too many? Does it need to be addressed, or can it wait until I add more OSD's, which will bring the ratio closer to ideal? I'm currently using only RBD and CephFS, no RadosGW. Thank you! Brad
