Change disk parameter after installation?

[kendou]

Regarding the disk allocated to cassandra nodes, the document says: "The amount of disk, in MB, allocated to a Cassandra node in the cluster. Note: Once this value is configured, it can not be changed." I'm using LVM as the underlying storage for cassandra, which enables me to dynamically expand the size of the logical volume and the file system. But if the disk parameter cannot be changed, I cannot benefit from this advantage.

Is it possible to add a feature to change the disk parameter after installation, or the only solution to increase the storage is add more agent nodes?

Alternatively, cassandra supports running across multiple disks. Can this be supported as well?
