 |
|
hi,
system: motherbord Z10-PE-D16 WS whit 2 xeon's
enabled raid in bios.
jumper on motherboard: LSI
created and initialized a raid1 on 2 SSD's of 500 GB
booted old system from nonraid SSD partition
raid /dev/md125 synced successfully
installed systemd gentoo on /dev/md125
copied config from old system to /usr/src/linux/.config in new system.
created kernel with
genkernel --lvm --mdadm --menuconfig all --makeopts=-j40 --oldconfig
dracut with dracut.conf
| Code: |
hostonly="yes"
use_fstab="yes"
add_dracutmodules+=" dm mdraid "
#omit_dracutmodules+=" systemd systemd-bootchard systemd-networkd "
stdloglvl="3"
logfile="/var/log/dracut.log"
|
grub-mkconfig -o /boot/grub/grub.cfg on old system
booted new system
boot comes in dracut emergency mode
cat /proc/mdstat gives:
cat: /proc/mdstat: No such file or directory
then do:
modprobe md-mod
cat /proc/mdstat gives:
Personalties:
unused devices: <none>
mdadm --assemble --scan
alot of output
cat /proc/mdstat gives:
| Code: | Personalties: [raid]
md125 : active (auto-red-only) raid1 sde[1] sdf[0]
md126 : inactve sde[1] (S) sdf[0] (S)
216478 blocks super external:ddf
md127 : active raid1 sdb[0] sda[2]
9766305792 blocks super 1.2 [2/2] [UU]
bitmap 0/73 pages [0KB] , 65536KB chunk |
then
ctrl d
boot go's further:
and login root is ok.
what did I miss

Maybe
| Code: |
rc-update add mdraid boot
|
and in /etc/default/grub kernel line
| Code: |
rd.md.uuid=<uuid> rd.md=1
GRUB_PRELOAD_MODULES="...mdraid1x......"
#### couldnt hurt

Found a solution using initramfs in stead of dracut.
added in /etc/mdadm.conf:
| Code: |
ARRAY /dev/md/md127 UUID=92c9dbbc-0f40-405c-a954-b0801e235346
ARRAY /dev/md/ddf0 metadata=ddf
ARRAY /dev/md125 container=/dev/md/ddf0 member=0
|
btw: fake raid is used to be able to boot windoze from another partition on this array.
grub:cfgv contains:
| Code: |
menuentry 'Gentoo GNU/Linux' --class gentoo --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-454cb945-1e89-452f-9d4b-2687b59ef726' {
load_video
if [ "x$grub_platform" = xefi ]; then
set gfxpayload=keep
fi
insmod gzio
insmod part_gpt
insmod ext2
set root='hostdisk//dev/md126,gpt7'
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root --hint='hostdisk//dev/md126,gpt7' 454cb945-1e89-452f-9d4b-2687b59ef726
else
search --no-floppy --fs-uuid --set=root 454cb945-1e89-452f-9d4b-2687b59ef726
fi
echo 'Loading Linux 5.15.32-gentoo-r1-x86_64 ...'
linux /boot/vmlinuz-5.15.32-gentoo-r1-x86_64 root=/dev/md126p7 ro rd.debug
echo 'Loading initial ramdisk ...'
initrd /boot/initramfs-5.15.32-gentoo-r1-x86_64.img
}
|
why /dev/md126p7 has to be used is strange.
cat /prov/mdstat:
| Code: |
md125 : active raid1 sdc[0] sdb[2]
9766305792 blocks super 1.2 [2/2] [UU]
bitmap: 1/73 pages [4KB], 65536KB chunk
md126 : active raid1 sdf[1] sde[0]
487304192 blocks super external:/md127/0 [2/2] [UU]
md127 : inactive sdf[1](S) sde[0](S)
2164784 blocks super external:ddf
unused devices: <none>
|
if no /etc/mdconf is used sometimes boot device is /dev/md126p7 and sometimes /dev/md125p7 |
