Proxmox Windows VM looses UUID

Proxmox Windows VM looses UUID

I’ve encountered an issue a few times when Proxmox updates Machine types with updates.My Windows machines sometimes present errors as after updates no UUID is present. Some software’s don’t like this. You can test this on Windows by inputting wmic path win32_computersystemproduct get uuid Likely you may see “No Instance(s) Available.” A quick fix I’ve found is to have a UUID set in the VM config Going into your VM Config fileroot@proxmox01:/etc/pve/qemu-serverSet the following arguments args: -machine smbios-entry-point-type=32

Continuously updated zpool iostat

Continuously updated zpool iostat

 cmdwatch -n 1 zpool iostat -vy 1 1 For example, cmdwatch -n 1 zpool iostat -vy 1 1 will give us the detailed output from the last section, in an updated in-place format on the screen rather than scrolling. For truly interactive use, this is the superior way to check iostat on an ongoing basis. The only real disadvantage to using watch or cmdwatch to monitor zpool iostat in realtime is that when you ctrl-C out of its loop, it clears the screen one last time, rather than…

Media Stack – Jackett, Radarr, Sonarr, Plex, TransmissionVPN.

Going to break down my current media stack, as well as list what these tools are and what they do. As well as how you can use these tools together to have a great media automation setup. I’ll specifically be sharing my docker-compose files so you can easily set this up quickly. You can customize it to your needs afterwards. Or even run each service in it’s own VM. But why would you with docker being a thing? https://github.com/Jackett/Jackett Jackett…

Farewell Synology DS416

Farewell Synology DS416

I can’t recommend Synology enough. I’ve had this little guy running since 2017. With some questionable and not so questionable drives installed. I never had one single issue with it. In fact I really enjoy working with these NAS units. It never outgrew my storage capacity needs. However my need for 10GB networking, massive disk io, and speed did lead this relationship to the bitter end. I would gladly buy another Synology unit if they made a device reasonably priced…
