Hello, I am using glusterfs as the storage backend for the VM images, volumes for oVirt consist of three bricks, is it still necessary to configure the arbiter to be on the safe side? or since the number of bricks is odd it will be done out of the box? Thanks in advance Cheers Erekle _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Hi, An arbiter volume is a special class of replica-3 volume. Arbiter is special because the third brick of replica set contains only directory hierarchy information and metadata. Therefore, arbiter provides split-brain protection with the equivalent consistency of a replica-3 volume without incurring the additional storage space overhead. If you already have a replica volume in your config with three bricks then that config should be good. You do not need to create a arbiter. Hope this helps !!
