Is there a tool that will really attempt a reconnect from a client to
a single OST?
it would be helpful for those rare cases
when this happens and there is nothing really wrong with either.
i imagine original cause could be something as simple as repeated delays
on a very busy network?
Other OSTs from the same OSS remained connected to the same client
during this problem.
If umount and mount could be avoided,
it would be less disruptive to other processes on the client.
