Truenas Scale - how to remove options from GRUB_CMDLINE_LINUX_DEFAULT

[dawwe]

Hi!

I've been trying to configure GPU passthrough to my VMs and unfortunately managed to mess up the current configuration.

Not sure if this will cause my current issues with GPU passthrough, but I would like to remove these duplicate entries:

Code:

GRUB_CMDLINE_LINUX_DEFAULT="libata.allow_tpm=1 systemd.unified_cgroup_hierarchy=0 amd_iommu=on iommu=pt kvm_amd.npt=1 kvm_amd.avic=1 intel_iommu=on zfsforce=1 libata.allow_tpm=1 systemd.unified_cgroup_hierarchy=0 amd_iommu=on iommu=pt kvm_amd.npt=1 kvm_amd.avic=1 intel_iommu=on zfsforce=1"

I used following command to update options/parameters:

Code:

midclt call system.advanced.update '{"kernel_extra_options": "firstoption=value secondoption=value thirdoption=value"}

I've been trying to find documentation on how to remove options using midclt, but haven't really found anything useful yet. Have I missed or misunderstood something here?

Any help is appreciated!

I would try setting the kernel_extra_options to an empty string... that will bring it back to the iX original... then add back as you want.

I doubt that duplicates are harmful if values are aligned.

Thx!

Duplicate options are now removed.
