Converting VZFS Containers to the New Layout

After upgrading your system to Parallels Cloud Server 6.0, all legacy Containers continue operating on VZFS—the file system used by Containers in previous versions of Parallels Server Bare Metal and Parallels Virtuozzo Containers.

Note: You can convert VZFS-based Containers to the new Container-in-an-image-file (ploop) layout while you migrate them to the host running Parallels Cloud Server 6.0. To do this, use the vzmigrate --convert-vzfs --online command.

To convert a Container based on VZFS to use the new Container-in-an-image-file layout:

  1. Make sure that the /vz partition is formatted as ext4 .

    Containers with the Container-in-an-image-file layout can be used only on /vz partitions formatted as ext4 . For more information on converting the /vz partition to ext4 , see Creating Containers with the New Layout .

  2. Use the vzctl convert command to convert the Container. For example, to convert Container 101, you can run this command:

    # vzctl convert 101 --velayout 5

    If the --velayout option is omitted, the command converts a Container to the layout defined by the VEFSTYPE parameter in the global configuration file /etc/vz/vz.conf . For the Container-in-an-image-file layout, this parameter must be set to ext4 .
