The third node is used for gluster arbitration and perhaps I have to configure in it a quorum disk also to keep quorum in case of a node failure (not clear yet at my mind, still reading the docs). I am stuck at the moment at the fencing part of the setup. Reading through the docs it seems that I have only the option to setup hardware watchdog fencing. I would expect to be able to use external media such as IPMI, iDrac, HP iLO or UPS based power management (APC) though I can't find any info how these are configured at current version of Proxmox. In case of a network partition and not a node hardware issue, how is the watchdog going to behave? Is a healthy but disconnected node going to be power cycled? I will soon proceed with testing as soon as I manage to setup fencing though I wanted to better understand this part of fencing. Appreciate any feedback from your experience and use cases, Alex
