How to find description of error in error log? We have errors like these in our MySQL error log:
[ERROR] [MY-010211] [Server] Got error 203 when reading table 'xxx'
But I can't find anything about either MY-010211 nor error 203 in the documentation.
Where can I find more information about this error, or other errors like this in general?
Errors labelled [MY-XXXXXX] are MySQL 8.0 errors. You can find the definition for this particular error here https://dev.mysql.com/doc/mysql-errors/8.0/en/server-error-reference.html#error_er_reading_table_failed.
