Hi,
I have a cluster serving rbd and cephfs storage for a period of
time. I added rgw in the cluster yesterday and wanted it to server
object storage. Everything seems good.
What I'm confused is how to calculate the pg/pgp number. As we
all know, the formula of calculating pgs is:
Total PGs = ((Total_number_of_OSD * 100) / max_replication_count) / pool_count
Before I created rgw, the cluster had 3 pools(rbd, cephfs_data, cephfs_meta).
But now it has 8 pools, which object service may use, including '.rgw.root',
'default.rgw.control', 'default.rgw.meta', 'default.rgw.log' and 'defualt.rgw.buckets.index'.
Should I calculate pg number again using new pool number as 8, or should I
continue to use the old pg number?
