Yes, it's possible - Redhat distributes a script called raid-check that is a good example of this very thing. Documentation/md.txt talks about 'check' and 'repair' as valid words for sync_action in sysfs. The number of errors found will be reported to mismatch_cnt. These can be found at /sys/block/md#/md for your array. hth, Tregaron -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
