Cant connect to Metabase after Restart

Metabase crashed and the restart results in following error.

Tried to recover the Database with:

java -cp metabase.jar org.h2.tools.Shell -url jdbc:h2:/opt/metabase_backup/new/metabase.db.h2.db

I hope to get some help

Hi @niko.lanzer
It sounds like the database has become corrupted. You can try the details outlined in the troubleshooting guide:
https://metabase.com/docs/latest/troubleshooting-guide/application-database.html
If that doesn’t work, then it might be faster to recover your latest backup.

Please make sure that you don’t use H2 for production in the future:
