I have seen articles everywhere setting a VAXCluster using SimH and
Raspberry Pis but none with Linux desktops. I am putting together a
small network of 3 or four Linux machines and thought it would be kind
of neat to put together a small cluster and maybe even join Hecnet
with it. Anyway I am kind of a VMS noob (only been using it for about
4 years) and would appreciate any guidance I can get. The network is
simple. 4 machines hooked up to a switch and then the switch is
attached to my cable modem/router. All, IP's are static as well.
Thanks in advance,
Ray

The underlying hardware does not matter. From a simh point of view, your
VAXcluster running on Linux desktops would be no different from mine
running on Raspberry Pi.
In fact, I am now running Raspberry Pi Desktop (the x86 Debian variant)
on an old(ish) HP Zbook, and the simh VAX running there is very happy to
join the VAXcluster running on a ClusterHAT Pi stack (master (boot) node
+ 4 satellites)
I have found it easiest to set up the VAXcluster having one "master"
with 1 vote towards the quorum, and all others as "satellites" having 0
votes. Mind you, the cluster will survive even if the master node is
occasionally taken down for platform maintenance. The satellites will
freeze in cluster state transition until the master returns.
