(168*100)/3 = 5600. Rounded to the next power of 2: 8192 That’s a bit high for my taste — you’ll average 146 PGs per OSD assuming a uniform distribution. Though it is probably OK. Do you have any other pools? Remember that you need to include _all_ pools in the PG calculation, not just a single pool. — Dan
