Comment 40 for bug 1969247

@mrichtarsky from the logs, mysql was not able to redo the actions during the upgrade because the size of the ib_redo6 file was not multiple of innodb_page_size. However, the default of innodb_page_size is 16kb (https://dev.mysql.com/doc/refman/8.0/en/server-status-variables.html#statvar_Innodb_page_size), and 1712128/16 = 107008. Did you change the innodb_page_size global value by any chance? If you can share your configuration it might be helpful.
