I have a cluster that has 34 datanodes, each with (11) 1.2TB disks for hdfs. I added three new nodes but these only have (9) 1.2TB disks for hdfs. The new datanodes have been added but it seems that not all the file systems are seen by hdfs
When I look at one of the older datanodes, in hdfs-site.xml for dfs.datanode.data.dir all the files systems are listed (disk1 - disk11). On the new nodes, only disk1 thru disk6 are listed even though disk7, 8 and 9 are configure and mounted as file systems.
Question. How do I get these nodes to recognize the other disks? Can I edit the hdfs-site.xml and add them to the list? If so, what are the steps?
