 |
|
Hello,
I have a system using split-usr, openrc & lilo that is currently booting from an old 4.x kernel built with genkernel using gentoo-sources
I'm trying to switch it to gentoo-kernel-dist which is using dracut but I can't get it to boot.
This is my lilo config:
| Code: |
hercules /boot # cat /etc/lilo.conf
raid-extra-boot=mbr-only
boot=/dev/md1
lba32
prompt
timeout=59
image = /boot/vmlinuz-6.6.58-gentoo-dist
label = Production
read-only
append="init=/linuxrc rootdelay=60 root=/dev/md3 rootfstype=ext4"
initrd=/boot/initramfs-6.6.58-gentoo-dist.img
image=/boot/kernel-genkernel-x86_64-4.9.72-gentoo
label=Backup
read-only
root=/dev/ram0
append="init=/linuxrc ramdisk=8192 real_root=/dev/md3 rootfstype=ext4 domdadm"
initrd=/boot/initramfs-genkernel-x86_64-4.9.72-gentoo
|
In that lilo config above, the first kernel is the new gentoo-kernel-dist and the second kernel is my old 4.x gentoo-sources built using genkernel which still boots
Now the problem I have, is that if I use the dracut config below, it tries to boot from "root=UUID=7669f93e-bc5b-465e-9208-7ad7581c7dc3" which doesn't exist when dropped into the debug shell:
| Code: |
# PUT YOUR CONFIG IN separate files
# in /etc/dracut.conf.d named "<name>.conf"
# SEE man dracut.conf(5) for options
# dracut modules to add to the default
add_dracutmodules+=" mdraid "
# additional kernel modules to the default
add_drivers+=" dm_mod dm_mirror dm_log dm_region_hash "
# install local /etc/mdadm.conf
mdadmconf="yes"
# Only build for this host
hostonly="yes"
|
When in the emergency shell, /dev/md3 DOES exist, so I thought I could just change the above dracut config to include hostonly_cmdline="no" to stop it from using UUID's for boot, like follows:
| Code: |
# PUT YOUR CONFIG IN separate files
# in /etc/dracut.conf.d named "<name>.conf"
# SEE man dracut.conf(5) for options
# dracut modules to add to the default
add_dracutmodules+=" mdraid "
# additional kernel modules to the default
add_drivers+=" dm_mod dm_mirror dm_log dm_region_hash "
# install local /etc/mdadm.conf
mdadmconf="yes"
# Only build for this host
hostonly="yes"
hostonly_cmdline="no"
|
However, with the above config it DOES try to boot from /dev/md3 but now that DOESN'T exist, so by adding that hostonly_cmdline="no" option is some-how now stopping /dev/md3 from being created
How do I get this system to boot? I've gone through the dracut gentoo guide but it is very vague on booting from md devices and any troubleshooting related to that.
My live fstab uses the /dev/md devices to mount partitions:
| Code: |
/dev/md1 /boot ext2 noatime 1 2
/dev/md3 / ext4 noatime 0 1
/dev/md2 none swap sw 0 0
/dev/md4 /mnt/DataArray ext4 noatime 0 0
|
Any help would be much appreciated |
