Hi,
Some news, i have installed a fresh new mysql server and I get that after trying to create an Innodb table (it doesn't happen for all and I have reseted my.cnf and /var/lib/mysql to the default) :
InnoDB: The file already exists though the corresponding table did not
InnoDB: exist in the InnoDB data dictionary. Have you moved InnoDB
InnoDB: .ibd files around without using the SQL commands
InnoDB: DISCARD TABLESPACE and IMPORT TABLESPACE, or did
InnoDB: mysqld crash in the middle of CREATE TABLE? You can
InnoDB: resolve the problem by removing the file './sqldms/active_sessions.ibd'
