Hi Lon, and thanks again for all your answers. >>Whereas heart-beat interface was working fine. >>You can disable these by setting allow_kill="0" and/or reboot="0" >>(see qdisk(5)). => ok but in the case of a heart-beat failure, it will no more avoid the dual-fencing if allow_kill="0" and/or reboot="0" , right ? >> And after reboot, I can see "cluster not quorate" etc. >> This happens after both nodes boot, or just one? After both nodes reboot but this message appears only on one. >>If both nodes boot up with the third node off, they should still be able to >>form a quorum by themselves, even if qdiskd isn't running or its score isn't >>sufficient. It's a pair, no third node. Alain Moullé -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
