In all the Proxmox discussions, I can't say that I have heard or seen anything regarding the use of the UPS,.. Tripplite or APC or other.
I have only done a little searching regarding this and having seen much as of yet, but sometimes it's about the keyword order of the search.
Is there any pointed documentation on how to establish UPS support / power down on a Proxmox node. While mine isn't 'production' grade or priority, it would be nice to know that my node will power down properly over just shutting down with the battery is depleted.
I have an APC for my home lab server that's running Proxmox currently. This is the 1 thing I've found that XCP-NG does better than Proxmox, a UPS "just works".
For my Proxmox server, I have the UPS assigned to a VM. However, I haven't found a solution to shutdown the server from the VM that I like yet. All the online documentation I've seen says to use apcupsd or nut, and I'd rather not have to have anything non-standard running on it.
That's my long, whiny way of saying I just need to write a 1 liner script to do it. Come on man, it's not that hard! 😆
