hmm... one possibility is that rest of the nodes were down. but the name
node showed other nodes were up. If more than one datanodes were up,
this indicates some bug.
One last thing : grep for this block id at 10.100.11.31. You might see
some useful error message when the block was written.
thanks,
Raghu.
