RAID 1 Multi-ESP Boot Test

Scripts for testing bootc installation onto a RAID 1 array with multiple ESP (EFI System Partition) partitions -- one per disk -- so that any disk can boot independently if another fails.

Prerequisites

• podman
• qemu-system-x86_64, edk2-ovmf
• mdadm, dosfstools, e2fsprogs, util-linux

All scripts must be run as root.

Usage

1. Install bootc onto a RAID 1 array

sudo ./test-raid1-multi-esp.sh

This builds a test container image (CentOS Stream 10 based by default), creates 3 loop-backed disk images in /var/tmp/, assembles a RAID 1 array, runs bootc install to-existing-root, and verifies that every ESP received bootloader files.

To use a different base image:

sudo ./test-raid1-multi-esp.sh quay.io/centos-bootc/centos-bootc:stream10

2. Boot the installed system in a VM

sudo ./boot-vm.sh

This launches a QEMU VM with all 3 disks attached. Log in and verify the system works. Press Ctrl-A X to exit the VM.

3. Test degraded boot (single disk)

sudo ./boot-vm.sh --disk 1

This boots the VM from only disk 1, simulating a disk failure. You can substitute any disk number from 1 to 3.

4. Clean up

sudo ./cleanup.sh

Tears down loop devices, stops the RAID array, and removes the disk images.
