Cannot start VM after loading backup config file

[Fred974]

Hi,

For some reason we lost all access to the TrueNAS server and the only way to get access to it again was to do reset it to default.
Once we got access to it again, we loaded the backup of the config file and we got everything back to normal. However, when we try to start or Windows 2019 VM server we get the following error message:

Code:

[EFAULT] VM will not start as DISK Device: /dev/zvol/dbollenbergz2/dbollenberg/WinServer2019Std device(s) are not available.

Code:

Error: Traceback (most recent call last):
  File "/usr/local/lib/python3.8/site-packages/middlewared/main.py", line 137, in call_method
    result = await self.middleware._call(message['method'], serviceobj, methodobj, params, app=self,

    raise CallError(
middlewared.service_exception.CallError: [EFAULT] VM will not start as DISK Device: /dev/zvol/dbollenbergz2/dbollenberg/WinServer2019Std device(s) are not available.

Does anyone know how I can get the VM back online? Is there a way to created a new Vm reusing the data from original VM

Thank you all in advance

The Disk exist in the device list

Do I upload the encryption key the same way I did the config file?

I manage to get it working again by unlocking the pool
