This assertion and message were dropped in the 2.0.5 release because
they do not really indicate an error. The new message in this situation

  Missing request information for client notifications for operation
with result '...' (initiated before we came up?)

The most likely sequence in this particular case is that FILE-2 came up

and formed a cluster first, then fenced FILE-1 for being unseen. FILE-1 then finished coming up, joined the cluster, and got the notification
of its own fencing (which by the way means that either fencing is
misconfigured or perhaps you are using fabric fencing).
