What is the standard behavior of providers on failing hard drives?

GiulioGiulio Member
edited June 2020 in General

I have a dedicated server with OneProvider, that I believe is in the Online.net datacenter.

I have a dedicated server with two 1TB HDD that i use in Raid Z1 with FreeBSD.
Performance is low for a variety of factors but i do not care about that and it is more tha enough for the bargain price I'm paying.

I was wondering, what's the standard behavior of provider with Old and Pre_Fail drives. Should I wait for the disk to fail in order to get it replaced, with a small chance of both disks failing at the same time or may it be possible to ask for at least one replacement out of two before it fails?

Here are both smartctl outputs for reference:

    Your drives look fine. That field indicates what the attribute means (i.e. if the values in that field are near thresh, it indicates is early indicator of failure; whereas other attributes are likely to just indicate old age)

    What you want to look out for is:
    1. Failing tests
    2. Errors logged
    3. Pending sectors
    4. Offline uncorrectable sectors
    5. A high reallocated sector count

    If you are concerned, you should run a long test. There hasn't been one of your drive in a long time, so it's probably worth doing.

    Right now your disks are fine. just run a long test and see if it brings up any issues.

    I personally would expect to see drive replacement when its actively failing or indicating that it will fail soon (like "reallocated sector count" )

  • GiulioGiulio Member

    Thank you very much for your suggestions, the long test is now running on both disks. Given the age of the drive I guess the solution is to set up a cron and run test with alerts periodically in order to catch an eventually failing drive as early as possible?

  • SGrafSGraf Member, Patron Provider

    Just set up smartd (from smartmontools) for automatic monitoring :)

    For a set up and forget solution I'd suggest setting up smartd w/notifications as suggested by @SGraf ; and set up a monthly cron or similar job to long test the drives. One drive at a time is best.

    Is it possible that no type of self testing id supported by the disks?

    Edit: i believe that short and long are supported while offline is not

    The real killer for spinny drives are those Reallocated_Sector_Ct. If I saw one, I would replace it.
