Hi all,
I have a cluster consists of: 3 Monitors, 1 RGW, 1 host of 24 OSDs(2TB/OSD) and some pool as:
ap-southeast.rgw.data.root
ap-southeast.rgw.control
ap-southeast.rgw.gc
ap-southeast.rgw.log
ap-southeast.rgw.intent-log
ap-southeast.rgw.usage
ap-southeast.rgw.users.keys
ap-southeast.rgw.users.email
ap-southeast.rgw.users.swift
ap-southeast.rgw.users.uid
ap-southeast.rgw.buckets.index
ap-southeast.rgw.buckets.data
ap-southeast.rgw.buckets.non-ec
ap-southeast.rgw.meta
In which "ap-southeast.rgw.buckets.data" is a erasure pool(k=20, m=4) and all of the remaining pool are replicated(size=3). I've used (100*OSDs)/size to calculate the number of PGs, e.g. 100*24/3 = 800(nearest power of 2: 1024) for replicated pools and 100*24/24=100(nearest power of 2: 128) for erasure pool. I'm not sure this is the best placement group number, someone can give me some advice ?
Thank !
