Hello,
Environment:
* vSphere 4.0, two RHEL 6.x VMs with the matching VMWare perl SDK installed, and working;
* the same RDM already shared by the two VMs;
Goal: having this RDM act as a backend for a GFS2 filesystem shared by the two machines, and more in the future, using the cluster infrastructure provided by RHEL; these will use VMWare fencing;
References so far:
* http://blog.wains.be/2011/02/17/red-hat-cluster-vmware-esx-fencing/
* http://linuxdynasty.org/215/howto-setup-gfs2-with-clustering/
Problem: this "port" stuff...
In the second URL, the port is referred to as the exact path to the VMDK file for the matching VM; in the first URL, it is referred to symbolically.
So, what is this "port" exactly? Why can it be a symbolic name or a path to a VMDK? What should I use, and why?
For now, I have succeeded in doing a "fence_vmware_helper --server ip.of.vhost.server", but this port stuff prevents me from going further. The man pages installed with the RHEL cluster suite don't really help...
