This is what I read on hp forums, for safety I removed the controller entirely. The less HP stuff I use the better.

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 :)

HBA is not real pass-through of drives, it creates a raid 0 for each one, striping them. If the controller fails, you can’t read anything.

Got it, thanks! Yes for my personal use I rather not rely on HP hardware at all and disable the whole raid thing entirely.

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 :’(

I think i will go with the last one.

I read online that the controller failure is a thing and not that uncommon. I really don’t want to rely on HP hardware tbh.

Well fuck me now I’m scared. So, for him the problem is hardware raid?

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).
