Distributed

As the name implies, data is distributed across the bricks in the volume and across the nodes. This type of volume allows for a seamless and low-cost increase in available space. The main drawback is that there is no data redundancy since files are allocated between bricks that could be on the same node or different nodes. It is mainly used for high-storage-capacity and concurrency applications.

Think of this volume type as just a bunch of disks (JBOD) or a linear logical volume manager (LVM) where space is just aggregated without any stripping or parity.
