TIER: stopping the tierd when the volume goes down
If there are large number of files to be migrated and by this time if the volume goes down, then the tierd has to be stopped. But on a huge query file list it keeps checking for each file before stopping. If the volume comes up before the old tierd dies then due to the presence of old tierd new one won't be created. After the old one completes the task, it dies and the status ends up as failed. This patch will check if the status is still running and then let it continue its work. Else it will stop running the tierd.
