LVM volumes are not activated on boot

Version (k3OS / kernel)
v0.20.11-k3s2r1

Architecture
amd64

Describe the bug
Greeting! I created my own disk layout and installed bootloader. But when k3os boots all volumes not activated. Is there any workarounds?

To Reproduce

Packer boot_command

  default = [
    "rancher", "<enter>",
    "export K3OS_INSTALL_POWER_OFF=true", "<enter>",
    "export INTERACTIVE=true", "<enter>",
    "export K3OS_INSTALL_NO_FORMAT=true", "<enter>",
    "curl http://{{ .HTTPIP }}:{{ .HTTPPort }}/create-disk-layout.sh | sudo bash", "<enter>",
    "<wait5m>",
    "sudo -E k3os install", "<enter>",
    "1", "<enter>", "y", "<enter>",
    "http://{{ .HTTPIP }}:{{ .HTTPPort }}/config.yml", "<enter>", "y", "<enter>"
    ...install bootloader...
  ]

create-disk-layout.sh

readonly DEVICE=/dev/vda
readonly PART=${DEVICE}1


dd if=/dev/zero of=${DEVICE} bs=1M count=1

parted -s ${DEVICE} mklabel msdos
parted -s ${DEVICE} mkpart primary 1 100%
parted -s ${DEVICE} set 1 lvm on
parted -s ${DEVICE} set 1 boot on
partprobe ${DEVICE}
sleep 2

pvcreate $PART
vgcreate k3os $PART
lvcreate -n root -l 100%FREE k3os

mkfs.ext4 -F -L K3OS_STATE /dev/k3os/root

Expected behavior
All lvm volumes will be activated

Actual behavior
Without lvm k3os can't determine boot mode. If I specify mode via kernel (k3os.mode=disk) k3os can't mount root partition

I haven't double-checked but LVM should be present in the initrd. You may need a modules entry in your config.yaml.

Hi! i have attached a screenshot to description.
I tried to add lvm to modules and also specify 'vgchange -a y' to init_cmd => It can't find partition with K3OS_STATE label because a lvm volume is not activated.

@spigell, can you show us your config.yaml? I have successfully mounted a LVM RAID5 device but am now using mdadm for the same.

@ivan98 Hi. Here it is:

init_cmd:
- 'sudo vgchange -a y'
boot_cmd:
- 'sudo sh -c "echo GA_PATH=/dev/vport1p1 > /etc/conf.d/qemu-guest-agent"'
k3os:
  modules:
  - lvm
  - wireguard
