I had to point the yaml to a temporary location to get around a disk space issue. Now that I've got disk space under control, I want to remove the temporary data dir from the yaml (I have two other data dirs in there that will stay).</p> <p>1) Do I shutdown cassandra and copy/move all the files in that dir to one of the other data dirs (in the appropriate folder) and remove that entry from the yaml?</p> <p>or </p> <p>2) do I just remove the yaml entry and let the node "heal" itself of its missing data from the other nodes (in effect simulating a drive failure)?</p> <p>or</p> <p>3) something else?</p> <p>Thanks for any help? </p>
