Hi to all. any equivalent to LSI Patrol Read ? Here you can find a detailed description: http://fibrevillage.com/storage/176-megaraid-patrol-read-detail tl;dr: This process causes the drives to read the data by issuing read-verify commands. By using the read-verify command, the data from the drives is not transferred to the MegaRAID adapter unless an error is detected and reported by one or more drives included in the stripe. If a single drive reports an error within the stripe, the read patrol function initiates read commands to all the other stripe unit drives and the data for this single failing stripe unit is recreated by the MegaRAID adapter from the remaining data and parity stripe units. I don't think it's the same as a standard consistency check, because all LSI controller have both patrol read and consistency checks features, so there should be a difference in this. AFAIK, patrol read scan all sector of all disks, consistency check only scan used sectors. -- 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
