> We encountered a situation where the namenode dropped into safe mode after a
> temporary outage of an NFS mount.
> At 12:10 the NFS server goes offline
> Oct 8 12:10:05 <namenode> kernel: nfs: server <nfs host> not responding,
> timed out
> This caused the namenode to conclude resource issues:
> 2011-10-08 12:10:34,848 WARN
> org.apache.hadoop.hdfs.server.namenode.NameNodeResourceChecker: Space
> available on volume '<nfs host>' is 0, which is below the configured reserved
> amount 104857600
> Temporary loss of NFS mount shouldn't cause safemode.
