Unable to back up large container: Acronis Error: Module=0 Code=0, Tag=0

Resolution

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 -->
         <parameter>
                 <id>vzlin_backup_serializer11</id>
                 <category>plugins</category>
                 <short>Virtuozzo Backup plugin</short>
                 <load>
                         <params xsi:type="plugin_params_externType">
                                 <type>extern</type>
                                 <path>vzlpl</path>
                                 <arguments>
                                         <argv>VZABackupLibClient/VZABackupLibClient.so</argv>
                                         <argv>vzlin_backup_serializer11</argv>
                                 </arguments>
                                 <!-- Environment variables-->
                                 <envp>
                                         <item>
                                                 <name>ACRONIS_TMP_PATH</name>
                                                 <value>/vz/tmp</value>
                                         </item>
                                 </envp>
                         </params>
                 </load>
     

  3. Restart PVA Agent
