To disable DSEFS and remove metadata and data:
Remove all directories and files from the DSEFS file system:
dse fs rm -r <filepath>
Wait a while for all nodes to perform the delete operations.
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: - dir: /var/lib/dsefs/data
Disable the DSEFS entries in all
dse.yamlfiles on all nodes.
Restart DataStax Enterprise.
Truncate all of the tables in the
Do not remove the
dsefskeyspace. If you inadvertently removed the
dsefskeyspace, you must specify a different keyspace name in
dse.yamlor create an empty
dsefskeyspace (this empty
dsefskeyspace will be populated with tables during DSEFS start up).
Do not delete the
data_directoriesbefore removing the
dsefskeyspace tables, or removing the node from the cluster.
