[Gluster-users] Use GlusterFS as storage for images of virtual machines - available issues

Hi,

additional things:
The problems occured too, when I mount the volume on an fourth machine as client.

When I remove a node from volume and shutdown it then, all went OK.

Is there a setting to avoid an behavior like this? The quorum?

Here all the settings:
