LUKS, "no device found"

[Ian Eure]

I’m running into an issue trying to get FAI to install onto an 
EFI+LUKS+LVM disk setup on a laptop.  I’m using this config, which 
is a combination of the example LVM_EFI config and "Plain disk + 
LUKS + LVM2 example" and "Example using a GPT partition table and 
EFI/ESP partition" from the setup-storage(8) man page.

   # <type> <mountpoint> <size>   <fs type> <mount options> <misc 
   options>

   # entire disk with LVM, all in one partition

   disk_config disk1 disklabel:gpt fstabkey:uuid align-at:1M

   primary /boot/efi 512M vfat rw
   primary /boot          512M ext2 rw,noatime
   primary -         4G-  -    -

   disk_config cryptsetup
   luks:"changeme" - disk1.3 - -

   disk_config lvm fstabkey:uuid
   vg vg1  disk1.3
   vg1-root     /       3G-      ext4    noatime,rw
   vg1-swap     swap    RAM:100% swap    sw


But, when I try to use this config, the install fails with:

   Using config file: 
   /var/lib/fai/config/disk_config/LVM_LUKS_EFI
   Executing: wipefs -af /dev/sda1
   Executing: wipefs -af /dev/sda2
   Executing: vgchange -a y vg1
   Executing: wipefs -af /dev/vg1/root
   Executing: lvremove -f /dev/vg1/root
   Executing: head -c 2047 /dev/urandom | od | tee 
   /tmp/fai/crypt_dev_sda3
   Executing: vgchange -a n vg1
   Executing: vgremove vg1
   pvremove  /dev/mapper/crypt_dev_sda3
   (STDERR)   No device found for /dev/mapper/cyrpt_dev_sda3
   Command had non-zero exit code


A similar config 

I’m not sure what’s wrong.  Possibly "vg vg1  disk1.3" is trying 
to put the LVM volume directly in the primary partition, instead 
of the LUKS container?  But the "Plain disk + LUKS + LVM2 example" 
example does this same thing (with disk1.1), and presumably that’s 
correct.

Any pointers on what I’m doing wrong here?

Thanks,
