I would like to know if there are some users of this list using GFS for mysql databases. I have some issues with the replication delay (I need a sync time less than 3s between 4 DB servers) I'm planning to use GFS (setup on multipath GNBD devices and Gigabit network ) in order to share a database among multiples MySQL server. MySQL will use external lock method with MyISAM tables and GFS will be mounted with the noatime option. I was planning to test two scenarios: - multiple write servers, all gfs volume mounted RW - one write and 3 servers with database mounted RO Does someone get an experience with a similar setup and some feedback about perfomances and reliability ? Thanks Benoit
