No Space Left On Device though space is available

[Pallavi Palleti]

Hi all,

We are having a 60 node cluster running hadoop-0.18.2. We are seeing "No Space 
Left On Device" and the detailed error is 
 org.apache.hadoop.ipc.RemoteException: java.io.IOException: 
java.lang.RuntimeException: javax.xml.transfor
m.TransformerException: java.io.IOException: No space left on device

Surprisingly, there is no space issue. Still, it is giving above error. Can 
someone kindly let me know what could be the issue?

Thanks
