Creating pools

When you deploy a storage cluster without creating a pool, Ceph uses the default pools for storing data. You can create pools to logically partition your storage objects on the IBM Storage Ceph dashboard.

Before you begin

Before you begin, make sure that you have the following prerequisites in place:
