@Noel_0317 The directory /hadoop/dfs/name/ might be your Namenode data directory that contains the metadata in the form of fsimage and edits. So won't recommend deleting it if that's the case. You can confirm if this directory is indeed the NN data directory by checking the HDFS configuration. If the cluster is working and still taking writes, you can verify if the Namenode Data dir has been changed to a different mount point if the latest data available on it is from July.

Hi @Noel_0317 I am sharing few hdfs commands to be checked on file system level of hdfs. hdfs dfs -df /hadoop - Shows the capacity, free and used space of the filesystem. hdfs dfs -df -h /hadoop - Shows the capacity, free and used space of the filesystem. -h parameter Formats the sizes of files in a human-readable fashion. hdfs dfs -du /hadoop/file - Show the amount of space, in bytes, used by the files that match the specified file pattern. hdfs dfs -du -s /hadoop/file - Rather than showing the size of each individual file that matches the pattern, shows the total (summary) size. hdfs dfs -du -h /hadoop/file - Show the amount of space, in bytes, used by the files that match the specified file pattern. Formats the sizes of files in a human-readable. fashion Let me know if this helps.

@Noel_0317 Do you have rack awareness configured for the Datanodes? Also, check for any disk-level issues on the datanode. Try enabling Debug for block placement : log4j.logger.org.apache.hadoop.hdfs.server.blockmanagement.BlockPlacementPolicy=DEBUG
log4j.logger.org.apache.hadoop.hdfs.protocol.BlockStoragePolicy=DEBUG
