Volume Data degraded error

Hi we have a Netgear 314E, Raid 5 and I keep getting this error.  I have fixed it once by running balance and defrag but it is back again.  The firmware is 6.6.0 and we have Egnyte Storage sync running.  This was the suggested state we should keep it until Egnyte inform us to upgrade.  

 

This is the disk log.  What is it indicating?

  • Hi uptown30,

     

    I think the problem is with this:

     

    Device: sda
    Controller: 0
    Channel: 0
    Firmware: 01.01K02
    Class: SATA
    RPM: 7200
    Sectors: 3907029168
    Pool: data
    PoolType: RAID 5
    PoolState: 3
    PoolHostId: 7c6e33a8
    Health data
    ATA Error Count: 0
    Reallocated Sectors: 0
    Reallocation Events: 0
    Spin Retry Count: 0
    Current Pending Sector Count: 31
    Uncorrectable Sector Count: 31

    Temperature: 44
    Start/Stop Count: 15
    Power-On Hours: 23184
    Power Cycle Count: 15
    Load Cycle Count: 6

     

    There are uncorrectable and pending sectors already. Normally these are indicators that the HDD is faulty or getting there.

     

    Are you using X-RAID2?

     

    Volume in a degraded state as far as I know should still work, it just cannot tolerate anymore HDD failure.

     

    I would suggest that you try to do a back-up of your files then have the HDD above be checked then replaced.

     

     

    Regards,

    My hunch would be that disk sda is failing and the problem but it would be important to look at more logs to confirm.

    Can you send in the entire logs zip (see the Sending Logs link in my sig)?

    This says that disk 1 (Channel 0) is starting to fail.  There might be other issues that show up in other logs (mdstat.log for instance).

     

    Balance and defrag won't fix degraded volume errors btw.  Only resyncing the array can do that.

      If we do have to resync the array, does this means I have to back up the data, break the array and recreate it?

        sda is marked as failed on the data volume array. I would replace that disk.

  • Yes the company is the originator purchaser. I will get in touch with Netgear. I did send all the logs to mdmg. Would the Netgear requires the logs you have indicated?

      That I don't know.  But it makes sense for you to look in smart_history.log and then decide on disk replacement.

        Where do i see the smart_history logs?  I have just downloaded the entire log folder but nada.
