What preparation is required before adding back a datanode directory?

What preparation is required before adding back a datanode directory?

New Contributor

Back in Mar 2017, we lost a disk in one of our cluster nodes that was supporting one of the datanode directories /data/01/hadoop/hdfs/data. In HDFS, we removed the path from the datanode directories list. Now we have a new disk in place, but before I add /data/01/hadoop/hdfs/data back into the datanode configuration is there anything I need to do to first, before adding it and restarting the services that reguire configuration updates? Thanks

@Robert HeyerYou can add the directory and restart the required services. That would suffice.Thanks
