I took the conf generated here by Luci, your example, and another example from here[1], and I have made mine[2]. It has a fence action, but not a quorum disk yet, the two lvm-cluster resources I need, and one service definition, which would launch the VMs with a script made by me. I didn't specified a logical volume, because I want the whole VG locked. I can do that, can't I ? Obs: nobody has told me, but I guess that I should put your lvm-cluster.sh in /usr/share/cluster/, am I right? Am I thinking correctly now? Thank you, again. Obs: I don't need an IP section because all my services (that are IP-dependant, off course) run inside the VMs, and they have their own IPs, it don't matter which phisical server they are running on.
