HDFS data on disks isnt full but HDFS on ambari dashboard show 100%

but all data node disks are as the follwing



 df -h | grep  grid
/dev/sdb                   20G  9.6G   10G  50% /grid/sdb
/dev/sde                   20G   12G  8.0G  60% /grid/sde
/dev/sdc                   20G   11G  8.7G  56% /grid/sdc
/dev/sdd                   20G   12G  7.7G  61% /grid/sdd


so we can see that disks are not full - around - 50% of data

but HDFS on ambari show - 99%


how it can be ?

@Michael Bronson Can you paste output for hadoop fs -du -s -h /* and check hdfs configs for datanode data directory locations and check for the disk space of these directories specified for this property dfs.datanode.data.dir.
