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. -- Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
