Tons of unallocated space. What kernel messages do you get for the
enospc? It sounds like this will be one of the mystery -28 error file
systems. So far as I recall the only work around is recreating the
file system. There are two additional things you can try: mount with
enospc_debug mount option and see if you can gather more information
about the problem. Or try a 4.8rc1 kernel which as a large number of
enospc changes.
