Still could be significant. Do you run periodic media scrubs on that
And if it's not significant, then there's nothing that I can sugest
that woul dhave caused the problem. For all we know about the state
of the system at the time the problem occurred, it could have been
caused by a cosmic ray flipping a bit somewhere in the IO path. i.e.
trying to diagnose a failure like this without any other errors
showing and no corrupt filesystem image we can examine is no better
than trying to guess where the needle is in a haystack...
