MySQL Error 3839: Invalid Redo Log Subdirectory Path
Description
This error occurs when MySQL attempts to start or configure InnoDB redo log archiving, but the 'subdir' argument is provided with a full or absolute path. MySQL expects 'subdir' to be a simple, relative subdirectory name, not a complete file path.
Error Message
Redo log archiving start prohibits path name in 'subdir' argument
Known Causes
3 known causesAbsolute Path in 'subdir'
The 'subdir' argument was specified as an absolute path (e.g., '/var/lib/mysql/archive') instead of a simple subdirectory name.
Path Separators in 'subdir'
The 'subdir' argument contained directory separators (like '/' or '\'), which are not permitted for this specific configuration parameter.
Misconfigured Archiving Parameters
The user incorrectly assumed 'subdir' should define the entire archive location, rather than just a subfolder within a predefined base directory.
