[Gluster-users] split-brain with quorum enabled

Hi all,

We are using glusterfs setup with a quorum turned on and the configuration
as the follows:

Nodes: 3
Type: Replicate
Number of Bricks: 1 x 3 = 3
cluster.quorum-type: fixed
cluster.quorum-count: 2
cluster.data-self-heal-algorithm: diff
cluster.server-quorum-ratio: 51%
glusterfs version: 3.5.3

Despite on the quorum is turned on sometimes we are still encounter a
split-brain occurrence after shutting down one node or all nodes together/

Is this is a normal behavior? What conditions could lead to this and how to
prevent split-brain occurence?
