    Raid verification errors on daily basis.

      How do you determine the cause or do i have a way of narrowing this down somehow?

          The RAID volume data verification process identifies any inconsistencies or bad data on a RAID 0, RAID 1, RAID 5, or RAID 10 volume.

            Ok it is my understanding that getting verification errors is not normal.  I have gone back and replaced each disk with a new disk, did a full check on the disk and a rebuild.  After performing this the system still has 1 to 9 verification errors on a daily basis.  So the basic question now is how to isolate a cause of having verification errors on a daily basis and solve the issue.

              The RAID volume data verification process identifies any inconsistencies or bad data on a RAID 0, RAID 1, RAID 5, or RAID 10 volume.

              The RAID volume data verification and repair process identifies and repairs any inconsistencies or bad data on a RAID 1, RAID 5, or RAID 10 volume.

              The following describes what occurs for each RAID level:

               

              RAID LevelVerifyVerify and Repair
              RAID 0Bad blocks are identified.N/A
              RAID 1Bad blocks are identifiedBad blocks are reassigned.
              Data on the mirror drive is compared to data on the source drive.If the data on the mirror drive does not match the data on the source drive, the data on the mirror is overwritten with the data on the source.
              RAID 5Bad blocks are identified.Bad blocks are reassigned.
              Parity is recalculated and compared to the stored parity for that stripe.If the newly calculated parity does not match the stored parity, the stored parity is overwritten with the newly calculated parity.
              RAID 10Bad blocks are identified.Bad blocks are reassigned.
              Data on the mirror is compared to data on the source.If the data on the mirror does not match the data on the source, the data on the mirror is overwritten with the data on the source.

                Well, if you continue with same verification errors after replacing the drives, it might be a problem with the SATA controller.
