[Linux-cluster] GFS 6.0 node without quorum tries to fence



Hi,
I have three nodes oben, mitte and unten. 

Test:
I have disabled eth0 on mitte, so that mitte will be excluded. 

Result:
Oben and unten are trying to fence mitte and build a new cluster. OK!
But mitte tries to fence oben and unten. PROBLEM!
 
Why can this happen? Mitte knows that it can not build a cluster. See
Logfile from mitte: "Have 1, need 2"

Logfile from mitte:
Aug  3 12:53:17 mitte lock_gulmd_core[1845]: Client (oben) expired Aug
3 12:53:17 mitte lock_gulmd_core[1845]: Core lost slave quorum. Have 1,
need 2. Switching to Arbitrating. Aug  3 12:53:17 mitte
lock_gulmd_core[2120]: Gonna exec fence_node oben Aug  3 12:53:17 mitte
lock_gulmd_core[1845]: Forked [2120] fence_node oben with a 0 pause. Aug
3 12:53:17 mitte fence_node[2120]: Performing fence method, manual, on

cluster.ccs:
cluster {
    name = "tom"
    lock_gulm {
        servers = ["oben", "mitte", "unten"]
    }
}

fence.ccs:
fence_devices {
  manual_oben {
    agent = "fence_manual"
  }     
  manual_mitte ...


nodes.ccs:
nodes {
  oben {
    ip_interfaces {
      eth0 = "192.168.100.241"
    }
    fence { 
      manual {
        manual_oben {
          ipaddr = "192.168.100.241"
        }
      }
    }
  }
  mitte ...
