Subject Cannot lock storage, directory is already locked
Date Wed, 25 May 2011 01:44:12 GMT
Hi guys,

I'm using an NFS cluster consisting of 30 machines, but only specified 3 of
the nodes to be my hadoop cluster. So my problem is this. Datanode won't
start in one of the nodes because of the following error:

org.apache.hadoop.hdfs.server.common.Storage: Cannot lock storage
/cs/student/mark/tmp/hodhod/dfs/data. The directory is already locked

I think it's because of the NFS property which allows one node to lock it
then the second node can't lock it. Any ideas on how to solve this error?
