Cassandra change data storage

Currently I'm using one disk for saving data of Cassandra. I want to switch to new disk (remove current) and keep the current data.

Do you have any ideas or suggestions?

You can just copy over the files (when the node is not running). Often your data is somewhere like /var/lib/cassandra/data.

  • shut down the node
  • copy all data to the new disk
  • mount new disk to the correct location
  • restart the node

That should be it.
