DELL R7425

[Wojciech Żardecki]

Hello all.
I have a problem with the installation on the DELL R7425 server.
I receive the "kernel panic" message
RAID controller set in HBA mode.
Please help me, what should I do to make the installation work successfully.
I connected to the server 64GB pendrive for FREENAS, and 6 SAS 600GB drives, for data.

Looks like you should have started this in a new thread instead of replying to this.

What are the server specs as that will help (Intel or AMD model)

Your RAID/HBA card is going to be very new and most likely isn’t supported. It looks like a system bus crash though. Like FreeNAS doesn’t have a good driver for any of the equipment. You are most likely going to have to put in a supported card.

You could virtualize on this machine, which you should pass the card through to FreeNAS. There are lots of Hypervisors that FreeNAS supports.

Maybe the admin can move your post?

Take a look at this to ensure your hardware is supported.

FreeNAS actively supports Intel as it’s the major vendor and has the most support from FreeBSD. But that doesn’t mean yours isn’t going to work.

As for the H730 card, I have one in mine and the performance is ok. It’s not fantastic. I will be swapping it and the caves for an LSI HBA native card to up the performance, flashed to IT mode. The H730 is supported using an LSI driver but the card has onboard cache (you should disable this) and for some reason does not give me the performance I would like to see. It’s just a limitation of the card design as I have been told. That card really wants to do RAID (don’t do this on FreeNAS).

I have FreeNAS virtualized on mine but you could run this bare metal. You just have to get those drives access to the hardware as much as possible. And the Epic processor probably uses a bus that is yet to be supported. Maybe that’s why you see these errors.

To troubleshoot, I would remove the HBA all together, fire it up and see if it’s still throwing errors. If so, remove additional components to see if the errors go away. If it’s board and bus... out of luck man. Virtualization may be your next step. There are lots at guides on this depending on your flavor of Hypervisor.

Hi. I just bought one of the systems AMD Epyc 7551s in it. Here's the real problem and it was discovered by John Baldwin on the FreeBSD project over a year ago. It's been merged into 12.0 and later.

These machines have exceeded the static number of irqs (255 previously) on the hardware due to the number of cores and devices on these machines. 64 cores and 128 threads... kewl, but it's a problem.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=229429

As can be seen from the bug, the new boards with all these cores need a change in the way the kernel initializes the number of interrupts on startup. John has proposed probing and dynamically allocating the number necessary on startup. I believe he ran his patch and it's all good and in 12.0. However, this critical patch on all the latest AMD Epyc goodness is not in 11.2 or was not merged in properly. I have the same issue with the:

panic: nexus_add_irq: failed

error on my machine with 11.2-U5 and it drops into the debugger showing a bunch of issues with acpi and other things that it's trying to allocate IRQs. I've contacted a couple of people I know on the project and I hope they will provide answers as soon as possible.

12.0 was released Dec 0f 2018 and, from what FreeNAS has shown, they are going to be a year behind in releasing.
