For example I have 5 nodes (1master) (4workers) Node0(master) Node1, Node2, Node3, Node4 On Node4 I have a lot of memory (disks) on another hand on nodes Node1, Node2, Node3 I have much less memory (disk) Is longhorn able to share memory from Node4 to pods which are scheduled on Node1,Node2,Node3? or I have to run pod on the node where the longhorn create disk? Is longhorn can handle this scenario?

Yeah, Longhorn can use storage on node A to host a volume replica for the volume engine on node B (the node where workload pod is running on)

it is out-of-the-box or should I configure something? @famous-journalist-11332?
