Still seeing some unexpected 'No space left on device' exceptions

                 Key: HADOOP-1189
                 URL: https://issues.apache.org/jira/browse/HADOOP-1189
             Project: Hadoop
          Issue Type: Bug
          Components: dfs
    Affects Versions: 0.12.2
            Reporter: Raghu Angadi
             Fix For: 0.13.0

One of the datanodes has one full partition (disk) out of four. Expected behaviour is that
datanode should skip this partition and use only the other three. HADOOP-990 fixed some bugs
related to this. It seems to work ok but some exceptions are still seeping through. In one
case there 33 of these out 1200+ blocks written to this node. Not sure what caused this. I
will submit a patch to the prints a more useful message throw the original exception.

Two unlikely reasons I can think of are 2% reserve space (8GB in this case) is not enough
or client some how still says block size is zero in some cases. Better error message should
help here.

If you see small number of these exceptions compared to number of blocks written, for now
you don't need change anything.
