# Plex Database Repair Refactoring - Completion Summary
|
||||
|
||||
## Task Description
|
||||
Refactor Plex Media Server management scripts to centralize database repair logic in a shared script (`plex-database-repair.sh`), remove duplicate/legacy repair logic from other scripts, and fix Unicode/ASCII display issues.
|
||||
|
||||
## Completed Work
|
||||
|
||||
### ✅ 1. Created Shared Database Repair Script
|
||||
- **File**: `/home/acedanger/shell/plex/plex-database-repair.sh`
|
||||
- **Features**:
|
||||
- Centralized database integrity checking and repair logic
|
||||
- Multiple repair strategies (dump/restore, schema recreation, backup recovery)
|
||||
- Proper WAL file handling for repair operations
|
||||
- File ownership correction after repairs
|
||||
- Command-line interface with check/repair/force-repair modes
|
||||
- Comprehensive logging and error handling
|
||||
|
||||
### ✅ 2. Updated Main Plex Management Script
|
||||
- **File**: `/home/acedanger/shell/plex/plex.sh`
|
||||
- **Changes**:
|
||||
- Added `repair_plex()` function that uses the shared repair script
|
||||
- Added user-facing `repair` command
|
||||
- Fixed Unicode/ASCII display issues in output
|
||||
- Integrated shared repair script for all database operations
|
||||
- Maintained backward compatibility with existing functionality
|
||||
|
||||
### ✅ 3. Refactored Backup Script
|
||||
- **File**: `/home/acedanger/shell/plex/backup-plex.sh`
|
||||
- **Major Changes**:
|
||||
- **Removed duplicate repair functions**:
|
||||
- `attempt_dump_restore()`
|
||||
- `attempt_schema_recreation()`
|
||||
- `attempt_backup_recovery()`
|
||||
- `recover_table_data()`
|
||||
- `cleanup_repair_files()`
|
||||
- `handle_wal_files_for_repair()`
|
||||
- `check_database_integrity_with_wal()`
|
||||
- **Updated integrity and repair functions**:
|
||||
- `check_database_integrity()` now calls shared repair script
|
||||
- `repair_database()` now calls shared repair script
|
||||
- **Fixed critical issue**: Restored missing `handle_wal_files()` function for backup operations
|
||||
- **Fixed typo**: Corrected `AUTO_REPAIR=false.service` to `AUTO_REPAIR=false`
|
||||
|
||||
### ✅ 4. Code Validation and Testing
|
||||
- **Syntax validation**: All scripts pass `bash -n` syntax checks
|
||||
- **Functional testing**:
|
||||
- Help systems work correctly
|
||||
- Database repair command integration successful
|
||||
- Backup script operations functioning properly
|
||||
- WAL file handling restored and working
|
||||
- **Error checking**: No remaining references to removed functions
|
||||
|
||||
### ✅ 5. Documentation
|
||||
- **File**: `/home/acedanger/shell/docs/plex-database-repair.md`
|
||||
- **Content**: Complete documentation of the shared repair script usage and features
|
||||
|
||||
## Key Benefits Achieved

|
||||
|
||||
## Final State
|
||||
|
||||
The refactoring is complete and fully functional. All Plex management scripts now use the centralized database repair system while maintaining their individual responsibilities:
|
||||
|
||||
- **plex.sh**: Service management and user interface
|

# Plex Database Repair Utility
|
||||
|
||||
## Overview
|
||||
|
||||
The `plex-database-repair.sh` script provides comprehensive database repair functionality for Plex Media Server. It has been extracted from the `backup-plex.sh` script to be reusable across multiple scripts in the Plex management suite.
|
||||
|
||||
## Features
|
||||
|
||||
- **Database Integrity Verification**: Uses Plex's custom SQLite binary for accurate integrity checking
|
||||
- **WAL File Management**: Properly handles Write-Ahead Logging files during repair operations
|
||||
- **Multiple Repair Strategies**:
|
||||
1. SQL Dump/Restore approach with validation
|
||||
2. Schema recreation with data recovery
|
||||
3. Recovery from previous backups
|
||||
- **Comprehensive Error Handling**: Graceful recovery and rollback on failure
|
||||
- **Ownership Preservation**: Ensures proper file ownership for the plex user
|
||||
|
||||
## Usage
|
||||
|
||||
### Command Line Interface
|
||||
|
||||
```bash
|
||||
# Check database integrity only
|
||||
./plex-database-repair.sh check <database_file>
|
||||
|
||||
# Attempt to repair corrupted database
|
||||
./plex-database-repair.sh repair <database_file>
|
||||
|
||||
# Force repair without prompts (for automation)
|
||||
./plex-database-repair.sh force-repair <database_file>
|
||||
```
|
||||
|
||||
### Integration with Other Scripts
|
||||
|
||||
The repair script is designed to be called from other scripts:
|
||||
|
||||
```bash
|
||||
# Source the script to use its functions
|
||||
source /path/to/plex-database-repair.sh
|
||||
|
||||
# Use functions directly
|
||||
check_database_integrity "/path/to/database.db"
|
||||
repair_database "/path/to/database.db" false
|
||||
```
|
||||
|
||||
## Examples
|
||||
|
||||
### Basic Integrity Check
|
||||
|
||||
```bash
|
||||
./plex-database-repair.sh check "/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-in Support/Databases/com.plexapp.plugins.library.db"
|
||||
```
|
||||
|
||||
### Repair Corrupted Database
|
||||
|
||||
```bash
|
||||
./plex-database-repair.sh repair "/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-in Support/Databases/com.plexapp.plugins.library.db"
|
||||
```
|
||||
|
||||
## Exit Codes
|
||||
|
||||
- **0**: Success (database is healthy or successfully repaired)
|
||||
- **1**: Database has issues but repair failed
|
||||
- **2**: Critical error (cannot access database or repair tools)
|
||||
|
||||
## Dependencies
|
||||
|
||||
- **Plex Media Server**: Must be installed with the custom SQLite binary
|
||||
- **Standard Unix tools**: `cp`, `mv`, `rm`, `chown`, `sync`
|
||||
- **sudo access**: Required for accessing Plex files and changing ownership
|
||||
|
||||
## Integration Points
|
||||
|
||||
### plex.sh
|
||||
|
||||
The main Plex management script uses this repair utility for:
|
||||
- Pre-startup integrity checking
|
||||
- Manual database repair command (`plex.sh repair`)
|
||||
|
||||
### backup-plex.sh
|
||||
|
||||
The backup script uses this utility for:
|
||||
- Pre-backup integrity verification
|
||||
- Automatic repair during backup process
|
||||
- Database corruption detection and handling
|
||||
|
||||
## Technical Details
|
||||
|
||||
### Repair Strategies
|
||||
|
||||
1. **SQL Dump/Restore**:
|
||||
- Creates a complete SQL dump of the corrupted database
|
||||
- Validates dump contains essential Plex tables
|
||||
- Creates new database from validated dump
|
||||
- Verifies integrity of repaired database
|
||||
|
||||
2. **Schema Recreation**:
|
||||
- Extracts schema from corrupted database
|
||||
- Creates new database with clean schema
|
||||
- Attempts table-by-table data recovery
|
||||
- Considers successful if 80% of tables recovered
|
||||
|
||||
3. **Backup Recovery**:
|
||||
- Locates most recent valid backup
|
||||
- Extracts and validates backup database
|
||||
- Replaces corrupted database with backup version
|
||||
|
||||
### WAL File Handling
|
||||
|
||||
The script properly manages SQLite Write-Ahead Logging files:
|
||||
|
||||
- **Prepare**: Performs WAL checkpoint and creates backups
|
||||
- **Cleanup**: Removes WAL/SHM files and restores WAL mode
|
||||
- **Restore**: Restores WAL/SHM files if repair fails
|
||||
|
||||
### Safety Measures
|
||||
|
||||
- Creates pre-repair backups before any modifications
|
||||
- Uses atomic file operations where possible
|
||||
- Forces filesystem sync after critical operations
|
||||
- Preserves original database if all repair strategies fail
|
||||
- Ensures proper file ownership and permissions
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
1. **Permission Denied**: Ensure script has sudo access and Plex files are accessible
|
||||
2. **Plex SQLite Not Found**: Verify Plex Media Server is properly installed
|
||||
3. **Insufficient Disk Space**: Repair process requires significant temporary space
|
||||
4. **Service Access**: Ensure Plex service can be stopped/started during repair
|
||||
|
||||
### Recovery Options
|
||||
|
||||
If repair fails:
|
||||
1. Check `backup-plex.sh` for recent backups
|
||||
2. Examine corrupted database directories for recovery files
|
||||
3. Consider manual database reconstruction using Plex tools
|
||||
4. Contact Plex support for advanced recovery options

#
|

# Author: Peter Wood <peter@peterwood.dev>
|
||||
# Description: Shared database repair functionality for Plex Media Server
|
||||
# Extracted from backup-plex.sh to be reusable across scripts
|
||||
#
|
||||
# Features:
|
||||
# - Database integrity verification with automatic repair
|
||||
# - WAL (Write-Ahead Logging) file handling
|
||||
# - Multiple repair strategies (dump/restore, schema recreation, backup recovery)
|
||||
# - Comprehensive error handling and recovery
|
||||
#
|
||||
# Usage:
|
||||
# ./plex-database-repair.sh check <database_file> # Check integrity only
|
||||
# ./plex-database-repair.sh repair <database_file> # Attempt repair
|
||||
# ./plex-database-repair.sh force-repair <database_file> # Force repair without prompts
|
||||
#
|
||||
# Exit Codes:
|
||||
# 0 - Success (database is healthy or successfully repaired)
|
||||
# 1 - Database has issues but repair failed
|
||||
# 2 - Critical error (cannot access database or repair tools)
