Hi, I recently upgraded my unraid server with a new CPU, Mobo and RAM.

 

Once I fired everything up and it was running fine, I upgraded to 7.1.2, and this is where the issues have started.

 

I have an NVMe drive (nvme0n1) for /cache, and I've had numerous issues with it becoming unmountable - file system issues.

I somehow seem to have sorted that out through trial and error, but almost immediately on the array starting I will get write errors and subsequently read errors if I try to read anything. It also seems to be locking up the web gui, attempting to download the logs has taken me numerous restarts.

I have done the following:

- Update BIOS to latest
- Replaced NVME, twice - including with a new NVME drive - issue persists
- Changed NVME slot on motherboard
- Remove NVME from array, format it, change the FS (tried zfs) - issue persists (have since changed back to btrfs)
- Ran memtest, passed, even tried one stick of RAM at a time, issue still persists

 

The log file is attached - it's only with the server running for a few minutes, as after this I can't seem to download the logs at all (it just hangs). Appreciate any help!

The NVMe device is being passed through to the VM, so when it starts it drops offline, edit the VM XML and remove this:

 

<hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x02' slot='0x00' function='0x0'/>
      </source>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x0a' function='0x0'/>
    </hostdev>

 

Thanks Jorge - I would have been trying to figure that out for some time! I have changed that and it's been running with 0 errors.
