Hi... I was wondering if it would be a good idea to fence without any type of hardware, besides the pc's. At the moment I have about 6 machines that I want to have a gfs on these 6 machines but due to budget constraints I cant afford to by hardware. How is it possible to fence without the use of hardware, besides manual fencing. These machines are your basic desktop pc's, each has a 80gig HD and a 3Ghz P4 processor. They are all connected by a 1 Gigabit switch. Would if be possible to use GFS or is there any other variant. They all run FC5( Fedora Core 5 ). I need some sort of GFS, because we intend on setting up a mysql clustering system as well. Any ideas would be greatly appreciated. He who has a why to live can bear with almost any how.

If you use system-config-cluster to configure your cluster, it will detect that you are fencing each node twice with a 'power switch' type of fence on the same level and set the appropriate attributes for you in the cluster.conf file. -J -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
