[SOLVED] New Arch installation "Unable to find root device"

I know there are ten million posts with the same issue, i read (almost) all of them bu nothing solved my problem yet.

I have lvm on luks, uefi, only arch, no other distro, no dual boot
an esp partition which i mount to /boot
an encrypted lvm partition which contains root and home (yes i use /dev/mapper/... when i need to mentaion root or home)

i've installed the base system. as a bootloader use grub. after boot it says

  ERROR: device 'UUID=...' not found . Skipping fsck.
ERROR: Unable to find root devide 'UUID=...'.

and falls back to the rootfs shell.

here is my fstab:

 # <file system>	<dir>	<type>	<options>	<dump>	<pass>
# /dev/mapper/vg-root
UUID=7a4ef8c0-0710-4a2a-9c50-21f11e19d966	/         	ext4      	rw,relatime,data=ordered	0 1

# /dev/mapper/vg-home
UUID=3fa813ad-64ff-4a34-bfe9-364c6c0bd33e	/home     	ext4      	rw,relatime,data=ordered	0 2

# /dev/sdc1
UUID=A011-86A8      	/boot     	vfat      	rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro	0 2

As i've seen in another post, my set root UUIDs were different than root UUID's so i changed them to be same. But didn't solve the problem. All my uuid's seem to me true. And i don't know why grub-mkconfig generates  a menu entry Arch Linux with linux-lts and also a sub menu for lts... But anyway even if i choose lts same problem occurs.Can't find root device.

My hooks order in my mkinitcpio.conf file is(which is mentioned in another forum):

 HOOKS="base udev block autodetect modconf keymap encrypt lvm2 filesystems keyboard fsck shutdown"

and my pacman.log is it's necessary(i don't see any error message):

Re: [SOLVED] New Arch installation "Unable to find root device"

I don't see a cryptdevice kernel parameter anywhere in your grub config.

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

thanks, you're right. But i'm not sure actually how should i do it. From the link you posted, it says:

device is the path to the raw encrypted device. Usage of Persistent block device naming is advisable.

If the encrypted device contains a LVM, the name of the volume group (vgname) containing the logical volume of the root partition serves as dmname. The parameter then takes the form of cryptdevice=device:vgname.

So, for example right now, it shows /dev/sda3 as the crypted lvm partition. When it it decrypted it will be:
/dev/mapper/vg-root  and /dev/mapper/vg-home

Should i do something like;
(as blkid /dev/sda3 gives me UUID of sda3)

 cryptdevice=UUIDof"/dev/sda3":vg-root

or it should be

 cryptdevice=UUIDof"/dev/mapper/vg-root":vg-root

or something else?

On the other hand, I've backuped my grub.cfg file from the previous installation(which was working) and i see those 3 lines which are not presented in new grub.cfg:

  1. insmod cryptodisk luks gcry_rijndael gcry_rijndael gcry_sha512 lvm
    I added these line to my new grub.cfg, i didn't work.

  2. insmod ext2.
    i realized that in my new grub.cfg all menu entires have "insmod fat", isn't it strange? these partitions are formatted as ext4. should i change it?

  3. set root='lvmid/someUUIDotherthanRoot'
    and i don't know if i should add a line like that? what it is for?

Re: [SOLVED] New Arch installation "Unable to find root device"

While using UUIDs is good practice on multi-disk/multi-partition setups, using encrypted LVM changes things. First, it's important to note that a logical volume, LUKS container and the underlying filesystem will all have their own UUIDs. That complicates things. Second, the lvm2 hook for mkinitcpio actually scans for volume groups and volumes and makes them available to the system under /dev/<volume_group_name> during boot-up. Logical volume names are unique, so using those device names in /etc/fstab and your GRUB config is both acceptable and simpler than using UUIDs.

So my volume group is called "Arch," and my two logical volumes are called "root" and "home." /etc/fstab looks like this:

# UUID=ef7ea498-e1a3-442c-b435-f330b7ebddfb LABEL=root
/dev/mapper/root    	/         	ext4      	rw,relatime,data=ordered	0 1

# UUID=bb1ac6f0-58fc-411a-aef7-8a4dc18e5c38 LABEL=home
/dev/mapper/home    	/home     	ext4      	rw,relatime,data=ordered	0 2

# UUID=eafcf9e2-6c04-4361-8a48-50a6a2d7c1c0 LABEL=boot
/dev/sda1           	/boot     	ext2      	rw,relatime	0 2

And my kernel line is this:

root=/dev/mapper/root cryptdevice=/dev/Arch/root:root:allow-discards rw quiet

So my root volume will be found during boot under /dev/Arch/root, unlocked, and mounted to /dev/mapper/root. Since you're using a volume group inside a LUKS container, that should be all you need, so consider booting up the LiveCD again, mounting your volumes and running genfstab without using UUIDs. Then change the kernel line in your GRUB config to match.

NOTE: The "allow-discards" bit is only used with SSDs, and might not even be necessary anymore (I'm not totally clear on that). Also, your fstab file won't exactly resemble mine, since /dev/mapper/home on my system is a second encrypted volume spanning two disks.

While using UUIDs is good practice on multi-disk/multi-partition setups, using encrypted LVM changes things. First, it's important to note that a logical volume, LUKS container and the underlying filesystem will all have their own UUIDs. That complicates things. Second, the lvm2 hook for mkinitcpio actually scans for volume groups and volumes and makes them available to the system under /dev/<volume_group_name> during boot-up. Logical volume names are unique, so using those device names in /etc/fstab and your GRUB config is both acceptable and simpler than using UUIDs.

Thanks a lot. It was also a useful answer. But infact i've solved the problem by reading    this post yesterday. Solution is the last message of emak and it's enough just doing:

 # vi /etc/default grub #modifing following line: GRUB_CMDLINE_LINUX="cryptdevice=/dev/sda2:vgroup"
# mkinitcpio -p linux
# grub-mkconfig -o /boot/EFI/grub/grub.cfg

It works now, only problem(not really a problem but) is, after password to decrypt the disk, it takes about 10 seconds to continue the process to arrive login manager, which seems to me quite long. Before the problems which led me to reinstall arch, it was taking less time. What can cause that?

It could just be the fact that all the files needed to boot now have to be decrypted first.

What sort of CPU do you have, does it have a hardware encryption module?
What encryption cipher are you using for your LUKS device?

The answers to these questions will affect the performance of your setup.

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan
