Hello MaaS’ists,
I need help in generating images from packer. and in deployment.
First I am having error in generating images for rhel and centos stream.
AlmaLinux and Rocky Linux image has been generated but deploying them with a raid commissioned machine is giving me problems.
I am less experienced in kickstart file and I am getting error after deploying image.
this is the current raid I am using
#!/bin/bash
# --- Start MAAS 1.0 script metadata ---
# name: 43-alma-raid-grub-setup
# title: Configure RAID and Install GRUB Bootloader for AlmaLinux
# description: Configures disk layout with RAID and installs GRUB on EFI partition
# script_type: commissioning
# timeout: 60
# --- End MAAS 1.0 script metadata ---
# Function to clean up on exit
cleanup() {
umount /mnt/sys 2>/dev/null
umount /mnt/proc 2>/dev/null
umount /mnt/dev 2>/dev/null
umount /mnt/boot/efi 2>/dev/null
umount /mnt 2>/dev/null
}
trap cleanup EXIT

- I am having problem compiling image from packer for centos and centos stream.
- This partition table works with ubuntu but I am getting hard time deploying RHEL based OS. cannot find bootable media after deployment on reboot. though I can see in the logs the deployment shows successful and Installation complete - Node disabled netboot message.
I am getting error when system boots after deployment and the OS can’t find any bootable partition or media and in MaaS I can see the raid configured correctly. I figure grub was not written properly to the partition.
Any Ideas what am I doing wrong?
