To continue with this quick start exercise, a minimum of one pool is necessary, created and hosted on one of the Mayastor nodes in the cluster. However, the number of pools available limits the extent to which the synchronous n-way mirroring feature ("replication") of Persistent Volumes can be configured for testing and evaluation; the number of pools configured should be no fewer than the desired maximum replication factor of the PVs to be created. Also, while placing data replicas ensure that appropriate redundancy is provided. Mayastor's control plane will avoid locating more than one replica of a volume on the same Mayastor node. Therefore, for example, the minimum viable configuration for a Mayastor deployment which is intended to test 3-way mirrored PVs must have three Mayastor Nodes, each having one Mayastor Pool, with each of those pools having one unique block device allocated to it.
