I'm not certain but if the disk develops hard problems, I'll assume
the host node will report it as an IO error and therefore the node is
considered as failed? I suppose the problem would be if the node
manages to read "something" after a retry.

Just giving my 2cents and hoping to stir up some interest in this :)
