hdfs dfs -du -h -s /
221.1 T 637.9 T /
hdfs dfs -du -h -s .
204.2 M 1.2 G .
But in the UI i see it's 670 T
I'm sure i'm missing something but cann't find it.

Could you run the below commands and post the results
I am curious , whats your replication factor ?
hadoop fsck path to directory hadoop fs -du -s path to directory
The above commands should give us the same results.
Both only caclulates hdfs raw data without considering the replication factor.
The below will calculate the file size across the nodes( hard disk ) and replication factor .
hadoop fs -count -q /path/to/directory
we can compare the results pertain to how much HDFS space has been consumed and run against Namenode UI results .

the non HDFS reserved space is 10 GB and for 30 nodes so it's should not exceed 1 T with replication factor 3.
it's really annoying.

is it becoming so annoying since the difference now between the UI ( or hdfs dfsadmin -report) and hdfs dfs -du -h -s now 150T, i delete all the hdfs snapshots and disallow them but still get the same results.
