Unanswered: 'sqlagent100_msdb_upgrade.sql' encountered error 200, state 7, severity 25.
I'm getting the following error after applying the service pack 2 on SQL server 2008 R2. Instance in not coming up.
Script level upgrade for database 'master' failed because upgrade step 'sqlagent100_msdb_upgrade.sql' encountered error 200, state 7, severity 25. This is a serious error condition which might interfere with regular operation and the database will be taken offline. If the error happened during upgrade of the 'master' database, it will prevent the entire SQL Server instance from starting. Examine the previous errorlog entries for errors, take the appropriate corrective actions and re-start the database so that the script upgrade steps run to completion.
