ext4: "fill_buffer on unknown block <BLOCKID> out of range"
I have seen a number of these appearing in my dmesg recently for a new-ish external disk. I'm afraid that it's a paraphrase, as I am away from the machine at present. ckfs.ext4 -f comes back clean and smartmontools reports nothing out of the ordinary. I have been running Picasa through wine, which is probably the application using the disk. What does this error imply? I'm guessing that they are failed writes, but if so, why is ckfs reporting that the filesystem is clean? I'm guessing that it means that data has been lost, but am uncertain how to determine which files are bad. Any advice or help would be appreciated - James
