Once a configuration file is created or edited (refer to Section 5.4 Creating a Configuration File for a New Volume), a pool volume can be created using the pool_tool command. Because the pool_tool command writes labels to the beginning of the devices or partitions, the new pool volume's devices or partitions must be accessible to the system. To create a pool, run the pool_tool command once from a single node.
The pool can be activated on any node by running the pool_assemble command. Refer to Section 5.6 Activating/Deactivating a Pool Volume.
In this example, the pool0.cfg file describes the new pool, pool0, created by the command.
pool_tool -c pool0.cfg
