Initramfs issue after creating array

[louisalvin]

Describe the bug This is my first ever bug report, so please tell me if I can make it better. This is potentially a duplicate of #21 .

While creating an array (Raid-5 in this case), the role runs correctly, including the arrays | Updating Initramfs task. The array is working correctly. However, after a reboot, the OS fails to mount the array because it was automatically renamed to md127.

Running update-initramfs -u manually and rebooting fixes the issue. Running this command after the role in Ansible seems to work too (cf. below).

To Reproduce Steps to reproduce the behavior:

1. Fire up a VM with 1 disk for system and 3 disks for storage; install Debian
2. Run the role from this repo. As an example, I had the following play and variables:

   - name: Raid-5 configuration
   hosts: all  # one single host
   become: yes
   tasks:
     - name: Include mdadm role
       include_role:
         name: mrlesmithjr.mdadm
     # - name: Update initramfs (bis)
     #   command: "update-initramfs -u"
     #   when: array_created.changed

   mdadm_arrays:
   - name: md0
   devices:
     - /dev/disk/by-id/scsi-0QEMU_QEMU_HARDDISK_drive-scsi1
     - /dev/disk/by-id/scsi-0QEMU_QEMU_HARDDISK_drive-scsi2
     - /dev/disk/by-id/scsi-0QEMU_QEMU_HARDDISK_drive-scsi3
   filesystem: ext4
   level: '5'  # Raid type (0, 1, 5, 6...)
   mountpoint: /srv/md0
   state: 'present'

   (When the three commented lines are un-commented, update-initramfs is run a second time, and things work as expected even after a reboot.)

3. Reboot the VM

Expected behavior The Raid array should keep the same name and therefore should be mounted without any problem.

Actual behavior At boot, the VM displays something like

[ TIME ] Timed out waiting for device dev-md0.device - /dev/md0.
[DEPEND] Dependency failed for srv-md0.mount - /srv/md0.
[DEPEND] Dependency failed for local-fs.target - Local File Systems.

The system boots in emergency mode and the lsblk command shows that the array is now called md127.

Desktop (please complete the following information):

• Target OS: Debian 12.1
• ansible --version:

  ansible [core 2.15.1]
  config file = /path/to/project/ansible.cfg
  configured module search path = ['/home/louis/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /home/louis/.local/lib/python3.10/site-packages/ansible
  ansible collection location = /home/louis/.ansible/collections:/usr/share/ansible/collections
  executable location = /home/louis/.local/bin/ansible
  python version = 3.10.12 (main, Jun 11 2023, 05:26:28) [GCC 11.4.0] (/usr/bin/python3)
  jinja version = 3.0.3
  libyaml = True

Additional context Note that when running the playbook, the arrays | Updating Initramfs task from this role seems to work (std_out is the usual "Generating /boot/..." and std_err is empty). But somehow, it needs to be run a second time to actually work.
