# RAID Bootloader Installation Script

A robust bash script for implementing RAID1 configuration for EFI boot partitions with multiple bootloader support. Designed for enterprise environments and high-availability systems, particularly optimized for Proxmox deployments.

## Features

- Multiple bootloader support (GRUB, systemd-boot, rEFInd, Limine, LILO)
- Automatic RAID1 array configuration
- EFI partition backup and restoration
- Comprehensive error handling and logging
- Support for both standard drives and NVMe devices
- Automated bootloader installation across all specified partitions

## Prerequisites

- Linux-based system (tested on Debian/Ubuntu)
- Root access
- mdadm package installed
- Supported bootloaders installed (as needed)
- Multiple drives with EFI partitions

## Installation

1. Download the script:
```bash
wget https://git.hhf.technology/hhf/raid-bootloader-installer-proxmox/raw/branch/main/raid_bootloader_install.sh
```

2. Make the script executable:
```bash
chmod +x raid_bootloader_install.sh
```

## Configuration

Edit the script to specify your EFI partitions:

```bash
EFI_PARTITIONS=(
    "/dev/sdd2"
    "/dev/sdb2"
    "/dev/nvme2n1p2"
    "/dev/sdc2"
    "/dev/nvme1n1p2"
    "/dev/sda2"
)
```

## Usage

Run the script as root:
```bash
sudo ./raid_bootloader_install.sh
```

## Logging

The script logs all operations to:
- Console output
- /var/log/raid_bootloader_install.log

## Safety Features

- Automated backup of EFI contents before operations
- Comprehensive error checking
- Safe mount/unmount operations
- Verification of root privileges
