+# ZFS Setup for sleeper-service
+
+## Overview
+sleeper-service now uses ZFS for enhanced data integrity, snapshots, and efficient storage management for the file server role.
+
+## ZFS Pool Structure
+
+### `filepool` - Main ZFS Pool
+This pool contains all system and storage datasets:
+
+```
+filepool/root         # Root filesystem (/)
+filepool/nix          # Nix store (/nix)  
+filepool/var          # Variable data (/var)
+filepool/storage      # NFS export storage (/mnt/storage)
+```
+
+## Storage Layout
+
+### System Datasets
+- **filepool/root**: System root filesystem with snapshots for rollback
+- **filepool/nix**: Nix store, can be excluded from frequent snapshots
+- **filepool/var**: System logs and variable data
+
+### Storage Dataset  
+- **filepool/storage**: Primary NFS export point containing:
+  - `media/` - Media files shared via NFS
+  - `downloads/` - Download directory (for Transmission when re-enabled)
+  - `backups/` - Backup storage
+  - `shares/` - General file shares
+
+## ZFS Features Enabled
+
+### Automatic Services
+- **Auto-scrub**: Weekly integrity checks of all data
+- **TRIM**: SSD optimization for supported drives
+- **Snapshots**: Automatic snapshots for data protection (to be configured)
+
+### Benefits for File Server
+1. **Data Integrity**: Checksumming protects against bit rot
+2. **Snapshots**: Point-in-time recovery for user data
+3. **Compression**: Efficient storage usage
+4. **Send/Receive**: Efficient backup to other ZFS systems
+5. **Share Management**: Native NFS sharing support
+
+## Deployment Notes
+
+### Before First Boot
+The actual ZFS pool creation needs to be done during installation:
+
+```bash
+# Example pool creation (adjust device names)
+zpool create -f filepool /dev/sda
+zfs create filepool/root
+zfs create filepool/nix  
+zfs create filepool/var
+zfs create filepool/storage
+
+# Set mount points
+zfs set mountpoint=/ filepool/root
+zfs set mountpoint=/nix filepool/nix
+zfs set mountpoint=/var filepool/var  
+zfs set mountpoint=/mnt/storage filepool/storage
+
+# Enable compression for storage dataset
+zfs set compression=lz4 filepool/storage
+```
+
+### Network Storage Integration
+The `/mnt/storage` ZFS dataset is exported via NFS to the home lab network (10.0.0.0/24), replacing the previous "files.home" server functionality.
+
+## Migration from Existing Setup
+When deploying to the physical server:
+1. Backup existing data from current file server
+2. Create ZFS pool on target drives
+3. Restore data to `/mnt/storage`
+4. Update client machines to mount from new IP (10.0.0.8)
+
+## Culture Reference
+Like the GSV *Sleeper Service*, this configuration operates quietly in the background, providing reliable storage services with the redundancy and self-healing capabilities that ZFS brings to the table.
