New install - issues with boot cmdlines (i'm assuming)

Hello,

I recently rebuilt a RAID array with news disks on my PC. I'm having issues now with booting into this new system.

Here's the output of

lsblk

root@archiso ~ # lsblk

The issue is that I'm having to manually run

partprobe

to get /dev/mapper/mdroot{1,2} to populate. At boot, it'll prompt to open /dev/mapper/mdroot but then hang on finding /dev/mapper/mdroot1 and /dev/mapper/linux0-root and then tell me the root account is locked therefor not getting me to the rescue screen.

Here's the output of /etc/kernel/cmdline:

nvme_load=yes rd.luks.uuid=luks-c3fe5524-cd73-4fa4-8d83-0b37a217cb9b rd.luks.uuid=luks-5954dac1-0544-4f9f-ad76-9a4c07d71727 rd.lvm.lv=linux0/root rd.md.uuid=74061e02:80b9df06:af6faf0c:1118aa96 luks.rd.option=fido2-device=auto root=/dev/mapper/linux0-root rootfstype=f2fs lockdown=integrity module.sig_enfore

Here's my /etc/mkinitcpio.conf:

# vim:set ft=sh
# MODULES
# The following modules are loaded before any boot hooks are
# run.  Advanced users may wish to specify all system modules
# in this array.  For instance:
#     MODULES=(usbhid xhci_hcd)
MODULES=(vmd dm_mod dm_crypt md_mod f2fs xfs vfat)

# BINARIES
# This setting includes any additional binaries a given user may
# wish into the CPIO image.  This is run last, so it may be used to
# override the actual binaries included by a given hook
# BINARIES are dependency parsed, so you may safely ignore libraries
BINARIES=(mdadm lvm partprobe)

# FILES
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in any way.  This is useful for config files.
FILES=(/etc/mdadm.conf)

# HOOKS
# This is the most important setting in this file.  The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added.  Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
# Examples:
##   This setup specifies all modules in the MODULES setting above.
##   No RAID, lvm2, or encrypted root is needed.
#    HOOKS=(base)
#
##   This setup will autodetect all modules for your system and should
##   work as a sane default
#    HOOKS=(base udev autodetect modconf block filesystems fsck)
#
##   This setup will generate a 'full' image which supports most systems.
##   No autodetection is done.
#    HOOKS=(base udev modconf block filesystems fsck)
#
##   This setup assembles a mdadm array with an encrypted root file system.
##   Note: See 'mkinitcpio -H mdadm_udev' for more information on RAID devices.
#    HOOKS=(base udev modconf keyboard keymap consolefont block mdadm_udev encrypt filesystems fsck)
#
##   This setup loads an lvm2 volume group.
#    HOOKS=(base udev modconf block lvm2 filesystems fsck)
#
##   This will create a systemd based initramfs which loads an encrypted root filesystem.
#    HOOKS=(base systemd autodetect modconf kms keyboard sd-vconsole sd-encrypt block filesystems fsck)
#
##   NOTE: If you have /usr on a separate partition, you MUST include the
#    usr and fsck hooks.
HOOKS=(base systemd udev autodetect microcode modconf kms keyboard keymap sd-vconsole sd-encrypt mdadm_udev lvm2 consolefont block filesystems fsck)

# COMPRESSION
# Use this to compress the initramfs image. By default, zstd compression
# is used for Linux ≥ 5.9 and gzip compression is used for Linux < 5.9.
# Use 'cat' to create an uncompressed image.
COMPRESSION="zstd"
#COMPRESSION="gzip"
#COMPRESSION="bzip2"
#COMPRESSION="lzma"
#COMPRESSION="xz"
#COMPRESSION="lzop"
#COMPRESSION="lz4"

# COMPRESSION_OPTIONS
# Additional options for the compressor
#COMPRESSION_OPTIONS=()

# MODULES_DECOMPRESS
# Decompress loadable kernel modules and their firmware during initramfs
# creation. Switch (yes/no).
# Enable to allow further decreasing image size when using high compression
# (e.g. xz -9e or zstd --long --ultra -22) at the expense of increased RAM usage
# at early boot.
# Note that any compressed files will be placed in the uncompressed early CPIO
# to avoid double compression.
#MODULES_DECOMPRESS="no"

I think what I'm missing here is a function to be able to add an initramfs script to run partprobe. Any help is appreciated.

Re: New install - issues with boot cmdlines (i'm assuming)

HOOKS=(base systemd udev autodetect microcode modconf kms keyboard keymap sd-vconsole sd-encrypt mdadm_udev lvm2 consolefont block filesystems fsck)

Choose systemd XOR busybox, not both (and probably try either)

So just to be clear; it's either base, or systemd. Not both, correct? Going to try tonight. I was under the impression you needed base no matter the situation.

Re: New install - issues with boot cmdlines (i'm assuming)

base is optional for systemd, mandatory for busybox - the overlap in your hooks is udev/systemd

Re: New install - issues with boot cmdlines (i'm assuming)

Removing systemd and adding base & udev gets me to a rescue screen finally. After having to add usbhid to MODULES and cryptsetup to BINARIES I'm able to bail out, unlock the first disk, partprobe, and then unlock the second disk and vgchange -a y to finally populate my root partition. BUT, am either rusty or ignorant as even after adding all partitions to /new_root and hitting 'exit' I'm getting the "/sbin/init is not found" warning and then kernel panic if 'exit' is prompted again. I'm having trouble remembering how to run-init manually. Normally I'd just add the root partitions to /new_root and exit. So, almost there.

I remember at some point in the past I was in a similar situation and was able to chroot into /new_root, add all of the necessary sysfs, devtmpfs, etc and somehow use systemctl to either run init or somehow initialize the system. But I'm sure there's an easier way.

Re: New install - issues with boot cmdlines (i'm assuming)

If you're going for busybox, sd-encrypt and sd-vconsole are wrong, https://wiki.archlinux.org/title/Dm-cry … mkinitcpio
