I am taking a partial backup from a Master server, which needs to be restored on a to-be slave server. I only need one of the databases, and the mysql database.
I am following instructions on https://www.percona.com/doc/percona-xtrabackup/2.2/innobackupex/partial_backups_innobackupex.html
The command I'm using looks like this:
innobackupex --user=<the_user> --password --databases="<database_name> mysql" --slave-info /path/backup
The prepare command looks like this:
innobackupex --apply-log --export /path/backup
And then I
Copy back the prepared backup to a “clean” datadir (in that case, make sure to include the mysql database).
MySQL starts fine, but without a performance_schema and with a lot of
588 [ERROR] Native table 'performance_schema'.'' has the wrong structure
on its error log.
Any idea why this might happen, and how to get the performance_schema back?
