Thanks for the support, in the end I opened the server removed the raid smart array controller and connected the drives directly to main board. Checked within the BIOS and I see them perfectly.
If you are looking for a HPE P440ar Smart array controller to buy hit me up :)
Okay after a some search looks like I have 3 options:
stick to my original plan but consider multiple points of failure (controller and Raid 0 on single disks)
The “IT” mode for HPE is called HBA but as far as I read it just creates a bunch of RAID 0 single drives (lol). I also need to update bios firmware because I don't have this mode on my controller (huge pain in the ass)
Just switch from the Dynamic Smart Array RAID to legacy SATA AHCI and bypass hardware raid completely and switch off the controller. I need to reinstall ubuntu and headscale though :’(
Mmm I personally rather avoid closed source software if I can. Afaik unraid is a whole os system that does all the work, so I also rather have different tools that do well their job than 1-in-all system. Decentralisation is always king. Plus I’m okay with not having a real time redundancy but just an easy snapshot system with Snapraid.
Every disk will be in a single array raid 0 with just itself. In other words, every array is just 1 disk in raid 0 (this because HPE doesn't have a no-raid option).
You are all banned from entering Italy. I will personally deport you all and put your asses in a reeducation camp.
This is tribalism, pure unadulterated satanic ritualistic shit. If jesus was here he would be crying now.
