Default Installation on LVM is not working

New Thread (Default installation of LVM not working):

First I did everything exactly as the LVM guide tells me. Then I continued with the Installation Guide. No extra options, no change from defaults. When I try to boot it, it fails.

I tried downgrading to 2.02.103-1. No result.

Old Thread (when I did not know that LVM was at fault):

Current state:

EDIT5: OK I have boiled it down to LVM. When I copied all files from etcvol to /etc in root it continued booting until it hit mounting /home... I have no idea what the §$%&/ is wrong.
Everything that is not root and should get mounted by fstab from LVM dies o.O
Even stranger: After I removed homevol and swapvol from fstab i get stuck at
 A start job is running for dev-sdb4.device

I did a "proof of concept" installation just now and it worked out of the box.

Parameters of the "proof of concept" installation:
/dev/sda5 ext4 /
/dev/sda4 EFI /boot
Rest is default installation guide

Gummiboot:

title          Arch Linux
linux          /vmlinuz-linux
initrd         /initramfs-linux.img
options        root=/dev/sda5 rw

Changed Parameters of the broken installation:
/dev/sda3 LVM on LUKS
Partitions
/dev/mapper/MyStorage-rootvol ext4 /
/dev/sda4 EFI /boot
/dev/mapper/MyStorage-swapvol swap
/dev/mapper/MyStorage-homevol ext4 /home

title          Arch Linux (Encrypted)
linux           /initramfs-linux.img
options        initrd=/initramfs-linux.img cryptdevice=/dev/sda3:MyStorage root=UUID=$UUIDofRoot rw

I added the HOOKS

HOOKS="... encrypt lvm2 keymap ... filesystems ... shutdown ..."

Fstab

So what goes wrong? I can't provide the exact logs as the journal persistency module dies in this case. If you know a way to get the actual files please tell me.

Everything works fine down to "Reached target Local File Systems"

I had a look at higher debug levels, but they all just showed systemd starting something which either failed or in the case of D-Bus died soon after.
When I broke into init, I could see the volumes which contained what they were supposed to contain.
Except that nothing really interesting. I noticed a complaint that the AHCI driver should be replaced against a specialized one. But I don't think thats the problem.

Thank you for your help!

Faked fsck.btrfs so mkinitcpio let me build a image
cp /bin/true /sbin/fsck.btrfs

1) Don't do this. Just remove the fsck hook.
2) If you read mkinitcpio's output, you'll see that it still created an image but warned you that it may not be complete.

So what goes wrong?

First everything is started alright.
Failed to start Recreate Volatile Files and Directories
Failed to start Update UTMP about System Reboot/Shutdown
Failed to start Trigger Flushing of Journal to Persistent Storage
5x start of D-Bus which get marked as OK, but in reality die soon after that check
Failed to start D-Bus System Message Bus
Failed to start Login Service

Paraphrasing this like doesn't help anyone. Post your logs verbatim, with context.

Removed the fsck filehook.

posted the fstab.

Boot logs will follow shortly. I just have to figure out how to get them in file form when the journal does not contain anything.

EDIT: OK I have no idea how to get my own boot logs sad but true. ill just try to add as much context as I can see but I can't possibly write all of this down by hand.

EDIT2: Ah no wonder when flushing of journal to persistent storage fails

EDIT3: Ill just start decreasing the complexity one by one. And as it is so easy ill start with btrfs.

EDIT4: Changing btrfs to ext4 did not change anything.

EDIT5: OK I have boiled it down to LVM. When I copied all files from etcvol to /etc in root it continued booting until it hit mounting /home... I have no idea what the §$%&/ is wrong.

Even stranger: After I removed homevol and swapvol from fstab i get stuck at

 A start job is running for dev-sdb4.device

EDIT6: Today I tried to make a "failsafe" system with lvm and luks. Turns out it is not failsafe.

First I did everything exactly as the LVM on LUKS guide tells me. Then I continued with the Installation Guide. No extra options, no change from defaults. The result is the very same I currently have.

EDIT7: Now that I think about it; There was something strange during pvcreate /dev/mapper/lvm. It complained: "/dev/sdc: open failed: No medium found" which is strange as there was never a /dev/sdc to begin with.
I'll try to install on a pure LVM partition without crypto.

EDIT8: OK pure install only LVM is also broken.
