-# proxmox-bindmounts-zfs
+# Proxmox Bind Mount Script
 
+A lightweight script to manage bind mounts across multiple Proxmox containers. This script allows for easy configuration of shared storage across containers and persists configuration for subsequent boots.
+
+## Features
+
+- Interactive first-time setup
+- Persistent configuration storage
+- Path validation
+- Safe unmounting and cleanup
+- systemd integration
+- Reconfiguration support
+
+## Prerequisites
+
+- Proxmox VE installed
+- Root or sudo access
+- Basic understanding of bind mounts
+- ZFS if using ZFS storage (recommended)
+
+## Installation
+
+1. Save the script to `/opt/bindmounts.sh`:
+```bash
+sudo wget -O /opt/bindmounts.sh https://your-script-location
+# or copy manually using your preferred method
+```
+
+2. Make the script executable:
+```bash
+sudo chmod +x /opt/bindmounts.sh
+```
+
+3. Create the systemd service file at `/etc/systemd/system/bindmounts.service`:
+```ini
+[Unit]
+Description=Bind mounts for containers
+Requires=zfs.target
+After=zfs.target
+
+[Service]
+ExecStart=/opt/bindmounts.sh up
+ExecStop=/opt/bindmounts.sh down
+
+[Install]
+WantedBy=multi-user.target
+```
+
+4. Enable and start the service:
+```bash
+sudo systemctl daemon-reload
+sudo systemctl enable bindmounts
+sudo systemctl start bindmounts
+```
+
+## First-Time Setup
+
+On first run, the script will prompt for:
+- Mount source path (e.g., /z/media)
+- Mount target path (e.g., /media)
+- Container base path (e.g., /z/pve)
+- Container IDs (space-separated list)
+
+This configuration is stored in `/etc/proxmox-bindmounts.conf`
+
+## Usage
+
+### Basic Commands
+
+1. Mount all configured containers:
+```bash
+sudo /opt/bindmounts.sh up
+```
+
+2. Unmount all containers:
+```bash
+sudo /opt/bindmounts.sh down
+```
+
+3. Reconfigure settings:
+```bash
+sudo /opt/bindmounts.sh reconfigure
+```
+
+### Service Management
+
+Start the service:
+```bash
+sudo systemctl start bindmounts
+```
+
+Stop the service:
+```bash
+sudo systemctl stop bindmounts
+```
+
+Check service status:
+```bash
+sudo systemctl status bindmounts
+```
+
+## Configuration File
+
+The configuration is stored in `/etc/proxmox-bindmounts.conf` with the following format:
+```bash
+MNT_SOURCE="/path/to/source"
+MNT_TARGET="/path/to/target"
+CT_BASE="/path/to/container/base"
+CT_IDS=(101 102 103)
+```
+
+## Security Considerations
+
+- The configuration file is created with 600 permissions (readable only by root)
+- The script validates paths before mounting
+- Unmounting is performed safely with proper cleanup
+
+## Troubleshooting
+
+1. If mounts fail:
+   - Check if source and target paths exist
+   - Verify container IDs are correct
+   - Check system logs: `journalctl -u bindmounts`
+
+2. If configuration is corrupted:
+   - Run `sudo /opt/bindmounts.sh reconfigure`
+   - Or manually edit `/etc/proxmox-bindmounts.conf`
+
+## Limitations
+
+- Currently supports one shared mount point across all configured containers
+- Requires manual configuration of systemd dependencies if not using ZFS
+- Must be run as root or with sudo privileges
