# PROBLEM `mysql.innodb_table_stats` is part of the MySQL 5.6 install. mysql_upgrade does not generate them. Why ? - When you install MySQL 5.6 from scratch, that file is generated. - The file `innodb_table_stats.ibd` does not exists in the mysql schema in MySQL 5.5 - MySQL 5.5's mysql_upgrade is not aware of any innodb system tables. - In fact, there are five(5) `.ibd` files in MySQL 5.6 in the mysql schema. # SOLUTION Please look at these posts I wrote last year on how to make them - `Dec 07, 2013` : https://dba.stackexchange.com/questions/54608/innodb-error-table-mysql-innodb-table-stats-not-found-after-upgrade-to-mys/54624#54624 - `Aug 15, 2013` : https://dba.stackexchange.com/questions/48166/cannot-open-table-mysql-innodb-index-stats/48189#48189 # Give it a Try !!!
