Excuse my top posting: Kaamesh, There are two types of quorum implementations: 1) cluster.server-quorum-type: server/none cluster.server-quorum-ratio: (0-100%) default >50% Whose behavior is to kill the glusterfsd daemons (server) if server-quorum-ratio is not met. 2) And we have quorum type: cluster.quorum-type: fixed cluster.quorum-count: 1 Whose behavior is to make the cluster read-only if the quorum is not met. In your case if you don't want the cluster to go down (Without adding another node to the cluster), disable the cluster.server-quorum-type: server, and use the `cluster.quorum-type: fixed and cluster.quorum-count: 1' options. In your volume options I see that you are using both the above methods to achieve quorum. ref: http://www.gluster.org/community/documentation/index.php/Gluster_3.2:_Setting_Volume_Options You can see some explanation in the above link. -sac ----- Original Message ----- > From: "ML mail" <mlnospam@xxxxxxxxx> > To: gluster-users@xxxxxxxxxxx > Sent: Monday, February 9, 2015 1:53:56 PM > Subject: Re: 2 Node glusterfs quorum help > > This seems to be a workaround, isn't there another proper way with the > configuration of the volume to achieve this?
