Managing Bricks

Brick is the basic unit of storage, represented by an export directory on a server in the storage cluster. You can expand, shrink, and migrate volume of you cluster, as required, by adding new bricks, removing bricks, and migrating bricks.

Note: You need to add at least one brick to a distributed volume, multiples of two bricks to replicated volumes, multiples of four bricks to striped volumes when expanding your storage space.
