Hi@Arun,

By default, the parameter "dfs.datanode.failed.volumes.tolerated" is set to 0, which means,the number of volumes that are allowed to fail before a datanode stops offering service. By default any volume failure will cause a datanode to shutdown.

To avoid this you have to set one property in hdfs-site.xml file.

<property>
    <name>dfs.datanode.failed.volumes.tolerated</name>
    <value>1</value>
</property>

Hope this will work.
