#. If using virtio disk, add driver to initrd::

echo 'filesystems+=" virtio_blk "' >> /etc/dracut.conf.d/fs.conf
|
|
|

#. Create empty cache file and generate initrd::
|

|
|
rm -f /etc/zfs/zpool.cache
|
|
touch /etc/zfs/zpool.cache
|

chmod a-w /etc/zfs/zpool.cache

#. Apply GRUB workaround::
|

|
|
sed -i "s|rpool=.*|rpool=rpool|" /etc/grub.d/10_linux
|
|
|
|
This workaround needs to be applied for every GRUB update, as the
|
|
update will overwrite the changes.
|
|
|
|
#. Install GRUB::
|
|
|
|
export ZPOOL_VDEV_NAME_PATH=YES
|
|
mkdir -p /boot/efi/fedora/grub-bootdir/i386-pc/
|
|
mkdir -p /boot/efi/fedora/grub-bootdir/x86_64-efi/
|
|
for i in ${DISK}; do
|
|
grub2-install --target=i386-pc --boot-directory \
|
|
/boot/efi/fedora/grub-bootdir/i386-pc/ $i
|
|
done
|
|
|
|
cp -r /usr/lib/grub/x86_64-efi/ /boot/efi/EFI/fedora/
|
|
|
|
#. Generate GRUB menu::
|
|
|
|
grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
|
|
grub2-mkconfig -o /boot/efi/fedora/grub-bootdir/i386-pc/grub2/grub.cfg
|
|
|
|
#. For both legacy and EFI booting: mirror ESP content::
|
|
|
|
ESP_MIRROR=$(mktemp -d)
|
|
unalias -a
|
|
cp -r /boot/efi/EFI $ESP_MIRROR
|
|
for i in /boot/efis/*; do
|
|
cp -r $ESP_MIRROR/EFI $i
|
|
done
|
|
rm -rf $ESP_MIRROR
|
|
|
|
#. Notes for GRUB on RHEL
|
|
|
|
As bls is disabled, you will need to regenerate GRUB menu after each kernel upgrade.
|
|
Or else the new kernel will not be recognized and system will boot the old kernel
|
|
on reboot.

|
|
zpool export -a
|
|
|
|
#. Reboot::
|
|

|
Wait for the computer to automatically reboot and the problem will be resolved.
