Question

For some reason there is a duplicate virtual environment running on a Virtuozzo node in OACI, having the identical ID and/or hostname and/or IP address. How to handle such cases properly?

Answer

Situations may differ based on the conditions:

  1. VEs are absolutely identical, but are running on different servers. OACI has a single entry for the VE.

    • Identify the reason why the duplicate appeared by examining logs from Virtuozzo and OA sides and decide which VE should be stopped and removed.
    • If VEs are running on top of a Virtuozzo storage, stop and unregister the duplicate:

      # prlctl stop <name>
      # prlctl unregister <name>
      
    • If VEs are running on top of standalone Virtuozzo nodes or one VE runs on a standalone node and another one runs on top of a storage node, stop and remove the duplicate:

      # prlctl stop <name>
      # prlctl delete <name>
      
  2. VEs have different configuration, but the same IP address and/or hostname. Both VEs are registered in OA.

    • Identify the reason why the duplicate IP address appeared and decide which VE should have the address changed. Make sure there is no reason for the IP address to be assigned again.
    • If the VE belongs to a New VPS Hosting subscription, login to CCP, navigate to VPS tab > Network settings and press 'Release'.
    • If the VE belongs to an OACI subscription, login to CCP, navigate to 'Cloud Infrastructure' tab > Your VE > Configure Network, press 'Delete IP Address' and press 'Add IP Address' afterwards.
  3. VEs have different configuration, but the same IP address and/or hostname. Only one VE is registered in OA.

    • Identify the reason why the duplicate IP address appeared.
    • If the non-registered VE is not requred, delete it:

      # prlctl stop <name>
      # prlctl delete <name>
      
    • If the non-registered VE is required for any purposes outside of OA, change its IP address to any other IP, not included into any IP pool in OA.
