[solved]Cryptdevice not asking for passwd, LVM not accessible

So,after the latest kernel upgrade, Arch won't boot.
What have I done so far;

First I ran this commands;

cryptsetup luksOpen /dev/sda ar ro
modprobe dm-mod
vgscan
vgchange -ay

Then I try to mount them, and chroot into my install.

mkdir /mnt/arch
mount /dev/ch/ro /mnt/arch
mount /dev/sda1 /mnt/arch/boot
mount /dev/ch/ho /mnt/arch/home
mount /dev/ch/va /mnt/arch/var
mount /dev/ch/tp /mnt/arch/tmp
arch-chroot /mnt/arch

This brings me into chroot, checking home dir, everything is oke, so far!
I try updating with pacman -Syyu, but no updates.
Reinstalled mkinitcpio and Linux,
Ran mkinitcpio -p linux, unchroot,unmount and reboot didn't solve it.
I was running grub legacy, installed Grub2 in chroot, but this leads me to the same problem.

What should happen normaly,
I boot and it should ask for the password to decrypt volume 'ch'.
It doesn't and comes with an error not being able to find the root device on /dev/mapper.
If it's not asking for the crypt-password in the first place, of course it won't be able to find the root-device;)
Perhaps boot is going to fast and it just runs over decrypting the LVM.

Maybe there is something wrong with my kernel line, but I don't see it,(

/vmlinuz-linux root=/dev/mapper/ch-ro ro cryptevice=/dev/sda2:ar ro 

My mkinitcpio.conf

MODULES="i915"
HOOKS="base udev autodetect modconf block filesystems usbinput fsck"

If I need to provide more info...)
Legenda: ar=cryptdevice   ch=LVM

edit:typo & mkinitcpio.conf

Re: [solved]Cryptdevice not asking for passwd, LVM not accessible

/etc/mkinitcpio.conf is relevant.

Re: [solved]Cryptdevice not asking for passwd, LVM not accessible

Your initramfs has no support for encrypted devices or lvm. What did you expect to happen?

Re: [solved]Cryptdevice not asking for passwd, LVM not accessible

To boot, like it has always done;)

So, I miss somethings in my mkinitcpio.conf, I will investigate , but it strikes me a little bit since I never changed anything.
Ah, I remember having a upgrade for mkinitcpio.conf a few days or more back, will look into it.


----------------


Update: after falconindy's hint') added lvm2 and encrypt to the hooks.

After that I ran; grub-mkconfig -o /boot/grub/grub.cfg  &&  mkinitcpio -p linux

The system boots, but I have to add; cryptdevice=/dev/sda2:ar ro    in grub by hand!

Re: [solved]Cryptdevice not asking for passwd, LVM not accessible

I suspect you may have decided to prune a bit too much out of your config when you merged the pacnew....

Re: [solved]Cryptdevice not asking for passwd, LVM not accessible

You're right, I did , after checking a backup this was evidently proven,)
I'm always careful when it comes to merging pacnew files, but you see...

I leave it partially solved, as I still have to add the line: cryptdevice=/dev/sda2:ar ro    in grub by hand!
I know I can edit grub.cfg, by why isn't it automatically created?

No idea. If your config is wrong, then change it.

Re: [solved]Cryptdevice not asking for passwd, LVM not accessible

I guess you're right I'll add the line to grub.cfg.
Problem solved!
Thanks for your time falconindy')
