In my experience that means that your data is corrupted.

You could try it, but as Guillaume Drolet mentioned I don't see this
helping.

Since this is happening on your original database, I suspect that's
what's been corrupted. In my experience, this means you either have
faulty hardware, or there's a misconfiguration that means fsync isn't
doing what it's supposed to do.
