Question: How to avoid schema failure after upgrade?
Answer:
The schema changes can fail or timeout, if the database is busy processing during the upgrade.
To avoid the schema failure, perform these steps before you upgrade:
- On all the nodes, run the vsh stop sudo command.
- Upgrade the analytics nodes first, then upgrade the search nodes.
- Run the /opt/versa/scripts/van-scripts/schema-check.sh command to check if schema is up to date.
