it’s not a distributed filesystem. it’s a distributed block device replication engine. The filesystem on top of that is still xfs or ext4 and can only be mounted on a single node at once.

So in order to use it I have to add a disk to each node of the cluster so that it syncs?

The LH docs cover this in great detail... but no, it creates virtual block devices on top of sparse files on your existing filesystem. Those virtual block devices are replicated, and mounted rw on a single node at a time.
