I'd like to use zfs with my Fedora 20 system.
I've installed the ZFS on Linux Fedora repository and subsequently the kernel-devel and zfs package. As far as I can tell, everything was installed successfully and I also rebooted the system. Nonetheless,
sudo zpool create outputs errors:
Failed to load ZFS module stack. Load the module manually by running 'insmod <location>/zfs.ko' as root.
Modprobe will also not load the module:
$ sudo modprobe zfs modprobe: ERROR: could not insert 'zfs': Required key not available.
insmod with either of the two locations of
zfs.ko I found on my system yields the same error:
$ sudo insmod /usr/lib/modules/3.16.3-200.fc20.x86_64/extra/zfs.ko insmod: ERROR: could not insert module /usr/lib/modules/3.16.3-200.fc20.x86_64/extra/zfs.ko: Required key not available $ sudo insmod /var/lib/dkms/zfs/0.6.3/3.16.3-200.fc20.x86_64/x86_64/module/zfs.ko insmod: ERROR: could not insert module /var/lib/dkms/zfs/0.6.3/3.16.3-200.fc20.x86_64/x86_64/module/zfs.ko: Required key not available
I'm booting with UEFI, having SecureBoot enabled.
I guess the kernel will only load modules that are signed with some trusted keys, probably those of the Fedora kernel team. For example
usb-storage apparently has such a signature:
$ modinfo usb-storage | grep '^sig' signer: Fedora kernel signing key sig_key: 55:46:C1:1D:28:CF:EC:0B:46:B1:C1:F1:93:0D:6B:F3:EC:63:B0:67 sig_hashalgo: sha256
What can I do to get ZFS running?
Edit: I've tried to disable Secure Boot and I could in fact load the module without a problem. I don't like it as a solution, as Secure Boot does provides some additional protection and my BIOS/UEFI delays my boot process to tell me it was booting insecurely.
