[jira] [Updated] (HDFS-16316) Improve DataNode to calculate used
capacity
[ https://issues.apache.org/jira/browse/HDFS-16316?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
JiangHua Zhu updated HDFS-16316:
--------------------------------
Description:
Something unusual happened in the online environment.
The DataNode is configured with 11 disks (${datanode.data.dir}). It is normal for 10 disks to calculate the used capacity, and the calculated value for the other 1 disk is much larger, which is very strange.
This is about the live view on the NameNode:

This is about the live view on the DataNode:
We can look at the view on linux:
There is a big gap here, regarding'/mnt/dfs/11/data'. This situation should be prohibited from happening.
