My setup is 3 node cluster. 78 osd and 3 mons. At the top of the cluster working radosgw on every machine. Every pool have a 3 replicas. Default politics for replicas is host in racks, and every machine is in other rack. When i do a stress test via s3 client, writing a lot of new object via balancer to the cluster i discovered, that only 3 osd are involved. This means that only one osd on every machine working in one time, when the object are writen via radosgw. Thats why i write this mail about increase number of pgs in radosgw pool. Maybe i am wrong, but how i can perform this better, more parallel, to use power of many drives (osd's) ?? =46or example when i use a rbd in this case, usage of osd devices is more random, and parallel.
