Hmm I think it will negate the MT epoll perf improvement. Try setting what Paul suggested and do gluster v info, if you see: server.event-threads: 1 client.event-threads: 1 In your gluster v info output then I think it will negate things. @Shyam - can you confirm / deny this? -b > > > > > > On Tue, Oct 13, 2015 at 2:53 PM, Lindsay Mathieson < > > [email protected]> wrote: > > > >> > >> On 13 October 2015 at 11:51, Paul Cuzner <[email protected]> wrote: > >> > >>> add > >>> # for epoll issue glusterd crash fix > >>> option ping-timeout 0 > >>> option event-threads 1 > >>> > >>> to your glusterd.vol files (/etc/glusterfs/glusterd.vol) > >> > >> > >> > >> > >> > >> Thanks, yah I saw that. > >> > >> Won't that remove the performance benefits though? > >> > >> -- > >> Lindsay > >> > > > > > > > -- > Lindsay > _______________________________________________ Gluster-users mailing list [email protected] http://www.gluster.org/mailman/listinfo/gluster-users
