unloading ipmi kernel module

[Henning Kessler]

Hello

I am trying to install FreeNAS 9.3 onto a Fujitsu-Siemens RX330 S1. but he reboot after the installation results in a panic. Watching the boot log I suspect the ipmi kernel module to be responsible for this. What would be the best way to do this? Can I alter the boot parameter in the Grub boot menu?

Regards

Henning

Does it panic immediately on load, or later on?

Throwing in "kldunload ipmi" as a pre-init script might be enough if it panics later but it sounds like it's falling down as soon as the module is loaded, which wouldn't give you the chance.

Unfortunately is panics immediately. I already tried to edit the boot parameters with

Code:

set ipmi_load="NO"

but that did not help either.

Can you disable the IPMI chip in BIOS, so perhaps it won't attempt to load the module? Alternatively, get one of the 9.2.1.* FreeNAS versions which comes with a boot image you can load on a USB stick. Then edit the boot image (?delete the module) before booting using a live CD which can read UFS.

Would it be possible to do this with the FreeNAS 9.3 USB stick itself? I could give openzfs for OS X a try ;-). If that does not work I will try to disable the IPMI itself..

I've no idea how easy that would be - you'd have to import the pool to read it without letting it automount anywhere harmful. Assuming openzfs for OS X has all the relevant features. Interesting though, I wonder if anyone round here knows how to do this?

That's generally not possible. IPMI is tied deep into the system BIOS and the Management Engine on most modern systems.

@Ericloewe Thanks for the clarification.

@rogerh I just tried it
Download & install openzfsforosx from here
plug in the USB stick, a warning will appear saying that the inserted media can not be read. just click on ignore.
open Terminal.app and run:

Code:

sudo zpool import -a

and then

Code:

zfs list

which results in this

Code:

NAME                        USED  AVAIL  REFER  MOUNTPOINT
freenas-boot                598M  6,61G    31K  none
freenas-boot/ROOT           590M  6,61G    25K  none
freenas-boot/ROOT/default   590M  6,61G   590M  legacy
freenas-boot/grub          7,23M  6,61G  7,23M  legacy

then I had to change the mount point from legacy to something OS X can work with

Code:

sudo zfs set mountpoint=/Volumes/ROOT freenas-boot/ROOT/default

and the Volume(?) "ROOT" will appear and you can edit stuff with admin privileges.
then you have to unmount the Volume and revert the mount point

Code:

sudo zfs set mountpoint=legacy freenas-boot/ROOT/default

and then I exported the stick

Code:

sudo zpool export freenas-boot

and unplugged the drive.

Tomorrow I can verify if the stick is still bootable.

Hello,
after a couple of try outs I found out the there was no issue with the ipmi kernel module. The problem was the onboard SATA controller (ServerWorks HT1000). After disabling it in BIOS freenas was booting like a charm...
