Create a storage pool
First, check if your provider supports any storage configuration attributes. For example, in the case of AWS, the ebs
storage provider supports several configuration attributes, and among these are volume-type
, which configures the volume type (i.e. magnetic, ssd, or provisioned-iops), and iops
, which indicates the IOPS per GiB.

ebs
, Wikipedia | IOPS
Second, use the create-storage-pool
command, passing as parameters the desired name of the pool and the name of the provider and then all the key-value pairs that you want to specify. For example, the code below creates a storage pool with the name iops
which is a version of ebs
with 30 IOPS.
juju create-storage-pool iops ebs volume-type=provisioned-iops iops=30

View the available storage pools
To view the available storage pools, use the storage-pools
command:
juju storage-pools
This will list all the predefined storage pools as well as any custom ones that may have been created with the juju create-storage-pool
command.
The name given to a default storage pool will often be the same as the name of the storage provider upon which it is based.

View the default storage pool
To find out the default storage pool for your block-type / filesystem-type, run the model-config
command followed by the storage-default-block-source
/ storage-default-filesystem-source
key. For example:
juju model-config storage-default-block-source
