Vinay commented on HDFS-5529:
-----------------------------
This issue is same as HDFS-2882 this is also one of the reason to fail the
initialization of Blockpool as mentioned in HDFS-2882
Latest patch attached to HDFS-2882 can make the datanode shutdown in this case.
> { Disk Fail } Can we shutdown the DN when it meet's disk failed condition
