As part of ODF ver. 15, NooBaa operator will run an automatic upgrade in order to update the DB data to work with this new version.
Will start the upgrade procedure and will add a 2nd init container running dumpdb.sh that will dump the old data.
in case of the DB pod using more than 33% of the attached PV space - this step will intentionelly fail and move to revert.
Will change the running version from 12 to 15 and add a 2nd init container running upgradedb.sh - this one will save the 12 data to a backup and will run the db_dump on the new 15 DB.
in case of the DB pod using more than 33% of the attached PV space - this step will intentionelly fail and move to revert.
Will remove the init container and will start a new db pod running version 15 with the new data.
In case of a failure in any of the above steps, will start the revert procedure and will add a 2nd init container running revertdb.sh that will copy the old data over the new and will start the OLD DB.
After revert has finished - will stop reconciling the new DB and will keep running the old pgsql version 12.
It will wait until new annotation will be added to NooBaa CR:
Will be used in case of expending the attached PV so that it will be using less than 33% - will restart the upgrade procedure from Prepare.
kubectl annotate noobaa noobaa retry_upgrade=trueWill be used after running a manual upgrade and will set the upgrade to finished.
kubectl annotate noobaa noobaa manual_upgrade_completed=trueDB upgrade has successfully finished and will never run again.
