Disabling DSEFS


To disable DSEFS and remove metadata and data:

  1. Remove all directories and files from the DSEFS file system:

    dse fs rm -r <filepath>
  2. Wait a while for all nodes to perform the delete operations.

  3. Verify that all DSEFS data directories where the file data blocks are stored locally on each node are empty.

    These data directories are configured in dse.yaml. Your directories are probably different from this default data_directories value:

        - dir: /var/lib/dsefs/data
  4. Disable the DSEFS entries in all dse.yaml files on all nodes.

  5. Restart DataStax Enterprise.

  6. Truncate all of the tables in the dsefs keyspace.

    Do not remove the dsefs keyspace. If you inadvertently removed the dsefs keyspace, you must specify a different keyspace name in dse.yaml or create an empty dsefs keyspace (this empty dsefs keyspace will be populated with tables during DSEFS start up).

    Do not delete the data_directories before removing the dsefs keyspace tables, or removing the node from the cluster.
