I want to increase innodb\_buffer\_pool\_size by setting in /etc/my.cnf under [mysqld]

innodb\_buffer\_pool\_size = 6144M

problem is, that it is ignored:

what could be the reason?

latest percona server  
ubuntu 12.04

Few things to Check,

1. See if there is no duplicate parameter set for innodb\_buffer\_pool\_size.
2. Check if the mysql is using /etc/my.cnf

Also if you could paste the my.cnf that would be good to check for errors.

ah, I’m stupid. I had another .cnf file in /etc/mysql/conf.d which overwrites the variables. everything is fine now 🙂
