Our cluster is complaining about the datanode directly space . It shows the below error on cloudera manager
Bad : The following DataNode Data Directory are on filesystems with less than 5.0 GiB of their space free. /mnt/hdfs/7/dfs/dn (free: 3.9 GiB (98.27%), capacity: 4.0 GiB)
When we checked the space on the disk only 1% of space is used up.
/dev/s 3.7T 17G 3.7T 1% /mnt/hdfs/7
We are not able to figure out the root cause of it as space is not our issue here. Can anyone throw some light on this?
