5.1 Adding a new pool #

To add a new pool, click Create in the top left of the pools table. In the pool form you can enter the pool's name, type, its applications, compression mode, and quotas including maximum byes and maximum objects. The pool form itself pre-calculates the number of placement groups that best suited to this specific pool. The calculation is based on the amount of OSDs in the cluster and the selected pool type with its specific settings. As soon as a placement groups number is set manually, it will be replaced by a calculated number. Confirm with Create Pool.
