Dear Ceph folks,
As the capacity of one HDD (OSD) is growing bigger and bigger, e.g. from 6TB up to 18TB or
even more, should the number of PG per OSD increase as well, e.g. for 200 to 800. As far
as i know, the capacity of each PG should be set smaller for performance reasons due to
the existence of PG locks, thus shall i set the number of PGs per OSD to 1000 or even
2000? what is the actual reason for not setting the number of PGs per OSD? Is there any
practical limations on the number of PGs?
thanks a lot,
Samuel
