degraded volume on NAS326 - SMART raw_read_error_rate

Options

Hi all

I have a degraded volume on my NAS326. But when I check the disk status, they all shows as "green". The only indicator is a raw_read_error_rate that one disks has, but not the other one. Do I need to replace a disk? Which one, left or right bay?

I habe a external usb disk with backups from this nas.

    The disk is toast. The Raw_Read_Error_Rate was 605 last Wednesday, and it's 755 now. In itself, that value is not a problem, but the rapid growth is. Further the kernel log shows the disk has severe problems.

    So you'd better replace it. It's the second disk, I suppose that is the right one, seen from the front. If you remove it, check the SMART of the remaining disk. If Raw_Read_Error_Rate is not zero, it was the wrong one. In that case just exchange the disks (with the NAS powered off). No harm is done.

    I /think/ that you have 'Current Pending Sectors', which are sectors which cannot be read, at the moment, due to a wrong checksum. That isn't necessarily a problem. Sometimes a bit flips. When you know that a bit on a modern harddisk is only a few square nanometers in size, and there are billions of them, it is easy to understand that after times some bits are flipped, or no longer readable. Especially bits which have not been written (= refreshed) for a long time. For that reason each sector has some parity bits to restore unreadable bits. But if too many bits are unreadable, and/or flipped, the recovery fails. That doesn't mean there is something wrong with that sector. It could be perfectly fine, yet unreadable. If you would write new data to it, it could store it.
    For that reason SMART doesn't call that disk unhealthy. It isn't. But on the same time the raid manager drops it, because it just sees the I/O error, when trying to read that sector, and has no other option. (If it was a bit higher-level, it could easily restore the data from the other array member. But it isn't)

    The 'Current Pending Sector count' should be in the SMART values. If it's unequal to 0, that is your problem. You can than simply repair the volume.

    Thank you very much for explanation Mijzelf. I tired now to repair the volume, but after "repairing" the volume goes back to the status degraded (screenshots below). I tried this multiple times. 'Current Pending Sector count' on both disks seems to be 0 (screenshots below).
    I also have access over SSH, if I need to do some commandline magic to get rid of this error.

    If the Current Pending Sector count is zero /after/ the disk is kicked from the array, that is not the problem. Before could be, as the disk only knows that the sector is unreadable after he tried to read it. And failure could be the reason to be kicked.

    The other values I can see (including Raw_Read_Error_Rate) are no problem. Unless they are growing fast. Unfortunately SMART gives information about the current (raw) value (including an interpretation from the manufacturer (Value and Threshold)) but no information about change in the current value.

    Using a shell you can read the kernel log (command dmesg) to see the low-level I/O errors which caused the kick. You can also get some more SMART info running

    su
    smartctl -a /dev/sda
    smartctl -a /dev/sdb
    

    but apart from Current Pending Sector I'm not aware of any disk error which can be ignored or repaired. On a PC you sometimes can exchange the Sata cables, in case SMART reports there is a bad data connection, but in a NAS that is not possible.

    Thank you for your answer Mijzelf. I entered the commands over ssh, but I have a hard time to interpret them. What would be the best next step? Maybe "factory reset" and delete all the volumes and recreate the raid? Or replace the disk (which one, left or right bay)?

    Edit: I saw the following error via dmesg: end_request: I/O error, dev sdb, sector 7999497
    Therefore this is the cause of the raid error? And disk /dev/sdb should be replaced?

    The disk is toast. The Raw_Read_Error_Rate was 605 last Wednesday, and it's 755 now. In itself, that value is not a problem, but the rapid growth is. Further the kernel log shows the disk has severe problems.

    So you'd better replace it. It's the second disk, I suppose that is the right one, seen from the front. If you remove it, check the SMART of the remaining disk. If Raw_Read_Error_Rate is not zero, it was the wrong one. In that case just exchange the disks (with the NAS powered off). No harm is done.

    Great, thank you very much for you analysis an explanation. I learned alot in the process. I replaced the right disk and now it's repairing/resyncing. After that I will check the Raw_Read_Error_Rate on both disks. If one has still error's I will switch the left one with the one I just pulled.
