Have you tried: echo 'check' > /sys/block/md<whatever>/md/sync_action ... that should report discrepancies between the two sides of the mirror ... Unfortunately, I don't think it reports which LBAs, but you could find this by hand using dd and md5sum or whatever. After that, if you do have discrepancies, then you can investigate what form they take by comparing the blocks from the individual block devices, and viewing them in a hex editor etc. etc. Tim. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
