There is a distinction to be drawn there, though, because we immediately pass
an error back to the client on a read, but a write problem in this situation
can be masked for an extended period of time.
That being said...

No reason to panic, yes. We can assume that if this was a very big persistent
problem, it would be much more widely reported. It would, however, be good to
find a way to get the error surfaced back up to the client in a way that is not
just monitoring the kernel logs.
