Re: 2 Node glusterfs quorum help

Quorum only appli‎es when you have 3 or more bricks replicating each other. In other words it doesn't mean any thing in a 2 node 2 brick cluster so it shouldn't be set.

In other words based on your settings it's acting correctly because it thinks that the online brick needs to have a minimum of one other brick it agrees with online.

Subject: [Gluster-users] 2 Node glusterfs quorum help

Hi guys. I have a 2 node replicated gluster  setup with the quorum count set at 1 brick. By my understanding this means that the gluster will not  go down when one brick is disconnected. This however proves false and when one brick is disconnected (i just pulled it off the network) the remaining brick goes down as well and i lose my mount points on the server. 
can anyone shed some light on whats wrong? 

my gfs config options are as following


Volume Name: gfsvolume
Type: Replicate
Volume ID: a29bd2fb-b1ef-4481-be10-c2f4faf4059b
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: gfs1:/export/sda/brick
Brick2: gfs2:/export/sda/brick

Thank You Kindly,
Kaamesh
