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 -
{code:java}
# 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 {code}
It is found in partition _/data/2_ instead of chunkinfo output _/data/1_
Cluster has 3 partitions - /data/\{1..3}
