Info
Upgrading the Omnistack Virtual Controller (OVC) to version 5.0.0 could potentially fail at 97 percent. When the failure occurs, the OVC will roll back the upgrade to the previous version and the services (svtfs) restart will fail. SimpliVity nodes that were deployed on version 3.7.9 or earlier and then upgraded to later versions are exposed to this issue due to an incorrect PostgreSQL configuration parameter. SimpliVity nodes that were deployed on Omnistack version 3.7.10 or later will not experience the issue.
Scope
All HPE SimpliVity Platforms.
Resolution
If this issue has already occurred, contact SimpliVity Support for assistance. If an upgrade is planned and this issue has not occurred, run the following command on all Omnistack Virtual Controllers in the Federation: #sudo su #grep -q "wal_level" /etc/postgresql/10/svtfs/postgresql.conf && sed -i 's/^.*wal_level.*$/#wal_level = replica/g' /etc/postgresql/10/svtfs/postgresql.conf || echo "#wal_level = replica" >> /etc/postgresql/10/svtfs/postgresql.conf Enter the commands on all nodes immediately before upgrading the OVC to version 5.0. Be aware that the changes will not persist following a reboot. Note: The workaround steps above can be safely run regardless of whether the node was deployed with Omnistack 3.7.9 or a later version. If you are unsure of the version used during deployment, it is better to run the workaround before upgrading to Omnistack 5.0.
