According to above output block path for node node8 is /data/1/hadoop-ozone/datanode/data/hdds/CID-3ff4197e-8f90-496f-bbaa-40ecf8bbb437/current/containerDir4/2048/chunks/113750153625602308.block

But on checking the actual node the block path found is - 

# find /data -name 2048
/data/2/hadoop-ozone/datanode/data/hdds/CID-3ff4197e-8f90-496f-bbaa-40ecf8bbb437/current/containerDir4/2048
# ls /data/2/hadoop-ozone/datanode/data/hdds/CID-3ff4197e-8f90-496f-bbaa-40ecf8bbb437/current/containerDir4/2048
chunks  metadata 

It is found in partition /data/2 instead of chunkinfo output /data/1

Cluster has 3 partitions - /data/{1..3}
