Parallels Virtual Automation backup tools use the /tmp partition for storing B-tree data for the file system of the container being backed up. If the container is rather big, the temporary file may require more free space in /tmp.


There are two ways to resolve the issue:

  • Bind-mount the /tmp partition onto a larger partition:

    # mkdir /vz/temp
    # mount --bind /vz/temp /tmp

    In order to preserve such behavior after a server reboot, add the corresponding record to /etc/fstab, e.g.:

    # echo "/vz/temp /tmp none bind 0 0" >> /etc/fstab
  • Change temporary storage location in PVA Agent backup plugin configuration (as of PVA 4.6.4 update 4 or 6.0):

    1. Edit /opt/pva/agent/plugins/VZABackupLibClient/VZABackupLibClient.voc
    2. Append parameter/load/params section for vzlin_backup_serializer11 with envp variables so the resulting section will look in a following way:

          <!-- vzlpl stuff -->
                  <short>Virtuozzo Backup plugin</short>
                          <params xsi:type="plugin_params_externType">
                                  <!-- Environment variables-->
    3. Restart PVA Agent
