[PVE-User] Proxmox Fencing

[Alex K]

Hi all,

I'm new to proxmox and trying to setup a 2 + 1 node active/active HA
cluster on top glusterfs using latest community pve-manager/6.4-4/337d6701
(running kernel: 5.4.106-1-pve). 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
