    I would make sure your os disk (is it flashmemory?) isn't failing and check your ram.

  • Thanks. NVME ssd (and the whole system) is quite new and I actually had RAM problems at the very beginning and resolved them when I changed it.


    The NVME is a Corsair Force MP510. Any ideas how I could check it?

    SMART. And I would check the ram again. Are you running the flashmemory plugin? nvme or not, it still has limited writes.

    I cannot activate SMART for the NVME drive. Not sure why!? Yes, I'm running the flashmemory plugin. Would it make sense to disable it temporarily for testing? Can I just enable it afterwards again?

    Definitely not. If smart isn't working, you may have a tougher time diagnosing this.

    Maybe the nvme drive is getting hot (especially when the system is under load?) and doing bad things? Otherwise, I would go back to the ram check.

  • the system is never really under load... it's waaaayyyy too overpowered, but i had most of the components laying around. maybe i will get some tools and check the ram. is there something i can install and test within OMV?

    Not that can really do as good as a job as memtest+.

    This specific SMART issue is because smartmontools is not updated in OMV5. The bug has been solved by smartmontools team, but the updated version is not showing up. Found it out just a while ago.
