Could this be called by an error to the external drive? Certainly. It could also be caused by the drive getting pulled before it was cleanly unmounted at some point in the past, and (especially if this drive was using flash) the inode allocation bitmap got corrupted. -- Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
