I at this point I would remove the host from vcenter and reinstall/reset config on the host.
There is a Vmware Host Performance sensor that gives you metrics on the host if thats what your looking for.
HA or autostarts its one or the other cant have both.
#1 is a new one that i havent seen before. Are you registering it from vcenter? I would remove it from vcenter make sure its not on the host, reboot and then reregister it from vcenter.
As long as your cluster doesnt have HA confgired you go to the host/configure/vm startup/shutdown.
I think all of your issues are related to you managing the host directly rather than from vcenter. vCenter has a config for each host internally and can overwrite any changes you make on the host itself to set it back to what it thinks it should be.
I would try searching for the model number in google you will probably find some r/c fourms as they use server psus for battery charging quite often.
You will have to jumper one or more of the small pins to turn it on to get the 12v out.
You can have drives of different sizes in zpools. The stipulations are that you have to add the same type of zfs and same size. So if you create a 7 disk raidz1 you can expand the pool by another 7 disk raidz1, not an 8 disk raidz1. IIRC you can not shrink a zpool.
I dont sleep the drives. I have gone back and forth on that but most of my drives are from older enterprise storage so the power on hours were high when I got them so didnt want to take a chance of the spin cycles taking them out.
I have only added: docker, snapraid, megerfs, and msmtp. So my installs are limited on the base os. Proxmox has built in data collector that i send to a grafana LXC, I have also tweaked the unraid Plex grafana dashboard to work with my plex lxc.
The one thing I dont know that you have with your...
Any reason you dont want to use proxmox as the base? It does zfs (w/e disks you want) boot out of the box with no fuss. Have your rootfs and your 10 disk pools for vms and LXC, for docker install on the base install or put it in a lxc or vm. I am currently running all of of the above. I have...
