MySQL Error 3615: Unknown Persisted Variable
Description
This error indicates that MySQL attempted to load a system variable from its automatically generated persisted configuration file (`mysqld-auto.cnf`), but the specified variable name does not exist or is not recognized. It typically occurs when a variable name is mistyped, has been deprecated, or manually introduced incorrectly into the persisted configuration, preventing the server from starting or applying the variable.
Error Message
Variable %s does not exist in persisted config file
Known Causes
3 known causesIncorrect Variable Name or Typo
The system variable name specified for persistence contains a typo or is not a recognized variable in the current MySQL server version.
Deprecated or Removed Variable
The variable was valid in an older MySQL version but has been deprecated, renamed, or removed in the current server version, yet still exists in the persisted configuration.
Direct `mysqld-auto.cnf` Editing
Manual modifications to the `mysqld-auto.cnf` file introduced an invalid or unrecognized variable entry, which MySQL then failed to parse.
