Upgrade multiple nodes with a single command

[mjacobs63]

I use this script on 5 PVE nodes and one PBS. Each time there is an upgrade, with is extremely frequent, I have to log in to each node individually to upgrade them. Since they are in a cluster, they have exchanged ssh keys and log in to one another passwordless. It should be relatively easy to create a list and run a for/in loop to upgrade them all. Or at a minimum, provide a switch that automates the "y" input during the upgrade so I can run my own loop.

Hi! I had also thought about adding the option to activate the automatic upgrade before each run... but for now I've put that idea on hold. I'm considering whether it's really safe to automate the process or whether it would be better for the user to do it consciously.
What do you think?
Your proposal is very valid. I have simultaneously started a separate project that could also incorporate this feature.

Hi, in the next release, the code will accept “y” as an addition to the --upgrade command, so if you run

proxsave --upgrade y

the prompt will be accepted automatically and therefore this command can be automated without having to start it manually on each server.

What do you think so far?
