I created a extra slave and created a XFS volume and mount it on the mysql dir slave was running fine until i noticed that the lag increase, and when i check, one query got stucked: 3 system user my_db Connect 9661 updating DELETE FROM blah blah this did not happen to my other slave which is running on ext3. any idea on which area i need to look first? i can't see anything on the logs for XFS errors, i have formatted my XFS with optimized option i red on the net and also optimized mounting options. but not sure why this is happening. By the way, xtrabackup is running on this slave as well, i'm not sure if that has something to do with it. Any help will be truly appreciated. Thank you in advanced. Regards, Ron
