High level steps


  1. run daexim to export mdsal
  2. run sqldump to export mariadb data (just in case)
  3. copy the files to backup directory
  4. helm delete/undelply --purge of sdnc
  5. cleanup k8 pvc, pv, secrets (modify cleanup.sh to not remove mariadb database
  6. DON'T remove dockerdata-nfs data
  7. helm deploy dev-sdnc .... for normal upgrade
  8. copy daexim json file to dockerdata-nfs/dev-sdnc/sdnc/mdsal0 if you mistakenly removed the dockerdata-nfs
  9. run daexim import of mdsal
  10. if mariadb was cleaned run mysqldump to import the databsase backup




Export Script (exportMdsal.sh)

Replace ODL_IP with your k8 host IP of sdnc-0 or set  ODL_IP in your environment

#! /bin/bash


ODL_USER=${ODL_USER:-admin}
ODL_PWD=${ODL_PWD:-Kp8bJ4SXszM0WXlhak3eHlcse2gAw84vaoGGmJvUy2U}
ODL_IP=${ODL_IP:-10.12.5.100}

curl -s -S -k -v -X POST -u ${ODL_USER}:${ODL_PWD} -H 'Content-Type: application/json' -d '{ "input": { "data-export-import:run-at": 10, "data-export-import:local-node-only": false } }' https://${ODL_IP}:30267/restconf/operations/data-export-import:schedule-export | python -mjson.tool


Import Script (importMdsal.sh)

Replace ODL_IP with your k8 host IP of sdnc-0 or set  ODL_IP in your environment

Make sure the backup json files are in /dockerdata-nfs/dev-sdnc/sdnc/mdsal0

If you get an error on netconf clustering not found make sure that the clustering:true setting is the same in both the export and the import ODL.

Mariadb Export/Dump

Log into the mariadb container via kubectl exec -it ...

         mysqldump -u sdnctl -p sdnctl > sdnctl.dump

[kubectl cp sdnctl.dump out of the container]

Mariadb Import

Copy the dump into the mariadb container

Log into the mariadb container via kubectl exec -it 

          mysql -u sdnctl -p sdnctl < sdnctl.dump
