Hi, I created a volume and have to restrict access now. Just one client should be allowed to acces the volume. So I tried: # gluster volume set sesam auth.allow 192.168.20.1 But I can still mount the volume from other clients than 192.168.20.1. But when I try to access the directory from an unallowd machine, my shell hangs. If I try to unmount, it says that the device is busy. The only way to get it out of the client is to kill the glusterfs process. And one more question: If I set a option by "gluster volume set" - how do I unset it? Regards, Marc
