Re: Update FC22 - doesn't find root fs and doesn't boot

Try by specifying luks in your /etc/crypttab (I do this just in case):

name UUID=... the-key-file/path luks

If you have 2 separate physical disks that must be decrypted before
detection of a partition (like with LVM), then you must have both in
the crypttab in the initramfs image. This was a problem for me with 2
physical disks, both separately encrypted, for creating a volume
group.

The issue is that depending on your configuration, the crypttab
generator in the crypt module may not see your 2 or more physical
disks comprising the root partition (it will only see the first). So I
had to hack mine, which is to comment out or remove the conditionals:

for _hdev in "${!host_fs_types[@]}"; do
- [[ ${host_fs_types[$_hdev]} == "crypto_LUKS" ]] || continue
- if [[ $_hdev -ef $_dev ]] || [[ /dev/block/$_hdev -ef
$_dev ]]; then
+ #[[ ${host_fs_types[$_hdev]} == "crypto_LUKS" ]] || continue
+ #if [[ $_hdev -ef $_dev ]] || [[ /dev/block/$_hdev

echo "$_mapper $_dev $_rest"
break
- fi
+ #fi
done
done < /etc/crypttab > $initdir/etc/crypttab
+ cat $initdir/etc/crypttab
mark_hostonly /etc/crypttab
fi

This is at /usr/lib64/dracut/modules.d/90crypt/module-setup.sh

This way you are forcing every encrypted partition into /etc/crypttab
in the initramfs image (where before it will not always match your
disks's copy). You may not actually want this, because you only want a
minimal image but if your key is the same for everything and every
disk is encrypted then it will not make a big difference. I would take
out of the key file and use none in the all /etc/crypttab for testing.
You will then have to type your password twice. This prompt may be
hard to see in all the output from systemd but sometimes you can just
press Return and it will appear clean.
