@asharma4 So you are from the same company that posted the other forum topic? Then why not just continue that thread instead of starting a new topic?
I don't understand what you mean by "provide sufficient supporting information". Try searching the internet, then you'll see a lot of people hitting this problem with MySQL (unrelated to Metabase).
Post the output of df -h from the server running MySQL.
- You can dump the MySQL application database to H2 with:
java -jar metabase.jar dump-to-h2 myapp.db - Then you change the application database connection environment variables to Postgres
- And then you load the data into Postgres with:
java -jar metabase.jar load-from-h2 myapp.db
Similar to a normal migration: https://www.metabase.com/docs/latest/operations-guide/migrating-from-h2.html
