Using 0.21 When I have a filesystem (XFS) with 1TB it detects the datanode detects it immediately. When I create 3 identical file systems all 3TB are visible immediately.
If I create a 6TB filesystem (XFS) and I add it to dfs.data.dir and I restart the datanode, "hdfs dfsadmin -report" does not see the new 6TB filesystem. In all of these occasions the datanode does create a 'finalized' file structure in respective directories? My questions are: Is there a limitation in the size of dfs.data.dir? What is the largest filesystem that can be part of it? Could this be a block scanner issue? Is it possible to make my block scanning more aggressive? -- --- Get your facts first, then you can distort them as you please.--
