Hi Bernhard, i have nearly the same setup: - Ubuntu 14.04. - 4 nodes (relplicate distributed) - bricks are on lvm on a mdadm raid 10 used bonding (802.3ad/bond-mode 4) before but did not see real benefit in speed for vms. depending on what you do 1 gb might be already enough. nevertheless we bought 10 ge hardware now For the vms i recommend to use libgfapi which will have better performance and the load of your gluster nodes will go down: http://www.gluster.org/community/documentation/index.php/Libgfapi_with_qemu_libvirt I also used these hints: http://www.gluster.org/community/documentation/index.php/Virt-store-usecase#Tunables Whats also important: http://joejulian.name/blog/keeping-your-vms-from-going-read-only-when-encountering-a-ping-timeout-in-glusterfs/ Regards André Am 18.12.2014 um 12:39 schrieb Bernhard Glomm: > hi all, > > I'm looking for some performance tuning suggestions for glusterfs. > > The set is: > - 2 server with several bricks each (ubuntu 14.04), > - each brick is part of a 2way-mirror between them both > - both server are connected with 2 * 1GB NIC > - the servers also mount the gluster volumes (fuse) > - each gluster volume hosts mainly a single large file (10-20GB) (VM-Image), > sometimes two or three of them > > My qustions: > - Which bond mode would you recommend for this set up? > - what are performance parameters/values for "few large files per gluster volume" > - are there some performance parameters regarding the use as vm.image storage > (the vms do some caching by themself?) > > TIA > > Bernhard > > > > _______________________________________________ > Gluster-users mailing list > Gluster-users@xxxxxxxxxxx > http://supercolony.gluster.org/mailman/listinfo/gluster-users > -- Mit freundlichen Grüßen André Bauer MAGIX Software GmbH André Bauer Administrator Postfach 200914 01194 Dresden Tel.
