RAID 1 Boot issue

I have just converted from Fedora to Arch and found only one issue during installation.

The Boot works, to a point, but after dmraid loads the raid correctly and each partition, loading the root partition without issue, it fails to load the boot partition or the swaper.
Log in and mount them manually, log out and the system is fine. Any ideas?

*** TRACE ***
Starting version 240
/dev/mapper/pdc_ifjidheip3: clean, 394575/117833728 files, 12746134/471322640 blocks

Your are in emergency mode. After logging in, type "journalctl -xb" to view
system logs, "systemctl reboot" to reboot, "systemctl default" or "exit"
to boot into default mode.
Give root password for maintenance
(or press Control-D to continue):

Using the password and mounting the two partitions manually works fine, then logout and the system lets you log in normally.

I know I've missed a step in grub or mkinitcpio, but I can't find it. Any help appreciated.

Re: RAID 1 Boot issue

Please post your mkinitcpio.conf and the config file for your bootloader

your partition setup might also be useful, post lslbk -f .

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=(piix ide_disk reiserfs)
MODULES=(amdgpu radeon dm_mod dm_mirror)

# 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=(/usr/bin/dmraid)

# 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/fstab)

# 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 block filesystems)
#
##   This setup will generate a 'full' image which supports most systems.
##   No autodetection is done.
#    HOOKS=(base udev block filesystems)
#
##   This setup assembles a pata mdadm array with an encrypted root FS.
##   Note: See 'mkinitcpio -H mdadm' for more information on raid devices.
#    HOOKS=(base udev block mdadm encrypt filesystems)
#
##   This setup loads an lvm2 volume group on a usb device.
#    HOOKS=(base udev block lvm2 filesystems)
#
##   NOTE: If you have /usr on a separate partition, you MUST include the
#    usr, fsck and shutdown hooks.
HOOKS=(base udev autodetect modconf block dmraid filesystems keyboard fsck)

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

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

grub config file should have been /boot/grug/grub.cfg , but the mkinitcpio.conf  and lslbk -f give enough clues to start troubleshooting.

You are using a raid 1 array on a dmraid setup. This means your initramfs needs support for both.
https://wiki.archlinux.org/index.php/In … _Fake_RAID mentions needing mdadm_udev hook .

$ mkinitcpio -H mdadm_udev
==> Help for hook 'mdadm_udev':
This hook loads the necessary modules for a RAID array and uses incremental
assembly via udev at runtime to create the devices. This hook will NOT work
without the udev hook included on the image.

Try adding mdamm_udev between dmraid and filesystems

I tried the mdadm_udev in hooks and it delayed a bit then retried 1 minute 30 seconds, then failed to mount the other partitions as usual.

Re: RAID 1 Boot issue

No solution so just dropped the RAID and rebuilt the boot options. Not ideal, but it is functioning the way Fedora used too - but still lacking drive encryption - for the same reason - its not easy to setup or manage on Arch.
