3.7. Shutting Down Virtuozzo Storage Clusters

To shut down a Virtuozzo Storage cluster completely, do the following:

  1. Stop all clients in the cluster. To do this, on each client:

    1. Shut down all running Containers and virtual machines.

    2. Unmount the cluster file system using the umount command. For example, if the cluster is mounted to the /vstorage/stor1 directory on a client, you can unmount it as follows:

      # umount /vstorage/stor1
      
    3. Disable the automatic mounting of the cluster by removing the cluster entry from the /etc/fstab file.

  2. Stop the shaman service and disable its automatic start:

    # systemctl stop shaman.service
    # systemctl disable shaman.service
    
  3. Stop all MDS servers and disable their automatic start:

    # systemctl stop vstorage-mdsd.target
    # systemctl disable vstorage-mdsd.target
    
  4. Stop all chunk servers and disable their automatic start:

    # systemctl stop vstorage-csd.target
    # systemctl disable vstorage-csd.target
