[SOLVED] GRUB2 does not process hooks: System doesn't boot

javex · 2012-08-10 15:42:20

My initial system was an SSD where /dev/sda1 was my boot partition and /dev/sda2 was an (encrypted) LVM containing home, root, var and swap. Since all partitions were ext3, I decided to do a clean format to ext4 and copy my data back on the partitions. First I archived everything but home with the arch live CD onto a server with:

rsync -a /mnt/* root@server:/path/to/backupdir/

Everything went fine, but after copying back, the system would not boot (it was GRUB Legacy). Since it was not in the MBR but on sda1, I figured I could upgrade to GRUB2 now. So I followed the described procedure (from a live CD) and installed GRUB2 (this time into the MBR of sda. I then regenerated the image via mkinitcpio -p linux and generated a configuration file.

When I try to start the system, GRUB2 gets loaded, but after the two messages for loading the ramdisk it remains silent for some time (no output at all) until it finally complains it cannot find my root. But I did not see any output of any hook being processed (including encrypt) so of course it cannot find my root, since it is still encrypted.

I reformatted my boot partition again and reinstalled and regenerated everything again (I copied the directory contents from my backup but moved the old grub folder). Still the same issue. I know I could probably just reinstall everything and restore the settings, but I'd really prefer to restore my system, since this should be a lot faster.

Here are the relevant configuration files:

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=""

# BINARIES
# This setting includes any additional binaries a given user may
# wish into the CPIO image.  This is run first, so it may be used to
# override the actual binaries used in a given hook.
# (Existing files are NOT overwritten if already added)
# BINARIES are dependency parsed, so you may safely ignore libraries
BINARIES=""

# 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.
# Some users may wish to include modprobe.conf for custom module options
# like so:
#    FILES="/etc/modprobe.d/modprobe.conf"
FILES=""

# 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 pata scsi sata filesystems"
#
##   This is identical to the above, except the old ide subsystem is
##   used for IDE devices instead of the new pata subsystem.
#    HOOKS="base udev autodetect ide scsi sata filesystems"
#
##   This setup will generate a 'full' image which supports most systems.
##   No autodetection is done.
#    HOOKS="base udev pata scsi sata usb 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 pata mdadm encrypt filesystems"
#
##   This setup loads an lvm2 volume group on a usb device.
#    HOOKS="base udev usb lvm2 filesystems"
HOOKS="base udev autodetect pata scsi sata keymap encrypt lvm2 resume filesystems usbinput"

# COMPRESSION
# Use this to compress the initramfs image. With kernels earlier than
# 2.6.30, only gzip is supported, which is also the default. Newer kernels
# support gzip, bzip2 and lzma. Kernels 2.6.38 and later support xz
# compression.
#COMPRESSION="gzip"
#COMPRESSION="bzip2"
#COMPRESSION="lzma"
#COMPRESSION="xz"
#COMPRESSION="lzop"

I also use LVM and had issues booting when I installed grub2. I don't remember the exact details, but I think it had to do with the UUID in the grub.cfg. I think getting rid of the if/then clause as a workaround also got me booting. Eventually I switched to syslinux.

Also, FYI: Grub has nothing to do with your HOOKS (and vise-versa). HOOKS are processed by mkinitcpio when creating your ramdisk.

Thank you for your reply. I looked further into the grub.cfg and removed the quiet part. Apparently the problem is that it runs all hooks but does not prompt me for a passphrase when running the encrypt hook. Why does this occur?

Edit: I solved this: apparently I forgot to specify a cryptdevice. Since the article about dm-crypt does not talk about GRUB2, I missed that. I will rework that section to specify GRUB2 and GRUB-Legacy

I would imagine it is simply because it is doing exactly what you are asking it to do... be quiet. It sounds like it is now working since you are now prompted for a passphrase? If this is the case, be sure to mark your thread as "solved" such that others might be able find their way here easily. If it is not solved, what is going on now?

javex · 2012-08-11 11:05:51

The thread's topic begins with [SOLVED] and my last post mentions the solution. What else should I do to mark it as solved?
Also: yes, the quiet flag was there, I removed it, it helped me track my error.
