This article documents troubleshooting steps to be taken if the Veeam vPower NFS Service fails to start.

Solution

Another process is locking the port used by the Veeam vPower NFS Service:

  1. Open an Administrative PowerShell Prompt
  2. Run the following command
Get-Process -Id (Get-NetTCPConnection -LocalPort 6161).OwningProcess
  1. Review the output. If the port is in use by another process, stop that process and start the Veeam vPower NFS Service.

    The results of the command will either list a process, or an error will be displayed stating that no objects were associated with the port. "Get-NetTCPConnection : No MSFT_NetTCPConnection objects found with property 'LocalPort' equal to '6161'.  Verify the value of the property and retry."
Example of output when no processe is locking port 6161
Example of output when no processes is using port 6161.

Example of output when Veeam vPower NFS Service is running correctly.

In versions of Veeam Backup & Replication prior to 10 (10.0.0.4461), the Veeam vPower NFS Service will fail to start if the RootFolder value in the registry contains a path that is not valid. Starting with Veeam Backup & Replication 10, if the RootFolder path value is invalid, the software will automatically default to C:\ProgramData\Veeam\Backup\NfsDatastore.

  1. Open Registry Editor
  2. Navigate to the following key:

    HKLM\SOFTWARE\Wow6432Node\Veeam\Veeam NFS

  3. The REG_SZ value named 'RootFolder' should have a valid path to a location within the filesystem. The most common issue is that the location points to a drive that is no longer present.

    Default Value: 
    C:\ProgramData\Veeam\Backup\IRCache\NfsDatastore
Shown is the rootfolder value in the registry with the default value
