It seems to me that you might want to preemptively add a few additional counters. A counter for WRITE_FILEMARKS, particularly non immediate count=0 ones, which are often used to flush the drive write buffer. A counter for movement related commands like SPACE/LOCATE/REWIND would also be helpful. Finally, abnormal read conditions like, ILI's, and hit FMs should have their own stat. Those three should provide a better view into how the drive is being used and why performance may not be what is expected. There may be others, but those three are high on my list of things I want to know about a tape stream that is not performing up to expectations. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
