CEPH placement groups and pool sizes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

Been doing some reading on the CEPH documentation and just wanted to clarify if anyone knows the (approximate) correct PG's for CEPH.

What I mean is lets say I have created one pool with 4096 placement groups.
Now instead of one pool I want two so if I were to create 2 pools instead would it be still 4096 placement groups per pool or would I divide it between the pools (e.g. 2048 pg per pool)

On a side note, per pool is that a recommended maximum of data before turning over to a new pool?

Regards

Pieter?
