Hi, I have acquired an HP Microserver Gen8 which I wish to use as a NAS. I have a few questions before I begin: Current hardware set-up: CPU upgraded to a Xeon 1265L V2 RAM upgraded to 16gb iLO4 disabled as I won’t use it I will disable the hardware raid in the BIOS I have 2x 3TB WD Red Nas HDDs …

There are reports of problems with that hardware under SCALE; see: [image] HP ProLiant MicroServer Gen8 instable on v25, OK on v24 and Debian12: kernel issue? TrueNAS General TL;DR: HPE ProLiant MicroServer Gen8 crashes with Unrecoverable System Error (NMI) err…

Thanks for that. So for now, it seems I’m better loading a previous stable version for the Gen8 (v24.10) ?

It seems like it–my Gen8 Microserver is still on CORE.

I am running 25.10 on a Gen8 Microserver with zero problems, nothing like in the thread linked. “Mileage” however is low and it does not have have separate HBA or any other card, maybe that makes a difference, too.

We’ve still got a fair few Microserver Gen8s deployed running 25.10 without any issues at all, none are using a PCIE HBA though. Beware that it’s not actually that easy to boot from the ODD bay (at least, last I checked); we worked around this by having a GRUB bootloader installed on a MicroSD in t…

[image] sanflan: boot from the ODD bay I gave up and used a USB-to-m.2 adapter to put a small SSD in the internal USB port–GRUB configuration is just way too obscure.

We’ve found using grub pointing to the ODD bay on an SD card internally it to be incredibly reliable and totally hands off if I’m honest. Should it be of interest I can grab a copy of the grub configs from one of those machines next time I’m with one of them? They even all survived without issue wi…

[image] sanflan: the addressed disk. As I recall (and it’s been a few years now), the “addressed disk” was the issue. I had two spinners installed, but I wanted a configuration that would be resilient to adding another pair of spinners at some time in the future–but that would have changed t…

I’m running 25.04.2.6 on mine; I started two or three main revisions ago (Bluefin Angelfish?) and it has been flawless. The installation method I used is described in my signature, which might be of interest. I too would recommend becoming familiar with iLO.

[image] Winnie: HP Microserver Gen8 I am running a HP Microserver Gen8 with TrueNAS 25.10.2.1 - Goldeye without any problems. It is upgraded to 32 GB RAM and has 240 GB SSD system/boot disk + 4 x 5.5 TB SATA disks.
