v2.5.0-rc1

Release Notes for Version v2.5.0-rc1

New Features:

• Global Variable Refactoring:
  • Made local_ip_list a global variable and enhanced the validate_drbd_resources_loaded function to improve resource validation across all DRBD nodes.

Enhancements:

• Script Refactoring:

  • Refactored email_alert.py to maintain compatibility with Python 2.7, ensuring support for older environments.
  • Optimized the watchdog initialization process to better handle PID changes, enabling more reliable service restarts.
  • Refactored variable handling to work seamlessly with arrays, improving script robustness and flexibility.

• Background Execution Support:

  • Rolled back the check_process_status function in the HA-Lizard watchdog to run in the background, ensuring non-blocking operations and improved system stability.

Bug Fixes:

• File Path Corrections:

  • Fixed issues with source file paths to ensure proper loading and execution of scripts.

• DRBD Resource Validation:

  • Rolled back incorrect validation logic for DRBD resources, which was preventing nodes from becoming primary under certain conditions. The updated logic ensures accurate validation and reliable resource management.

• Process Management:

  • Enhanced the watchdog process to correctly handle PID changes, reducing the likelihood of initialization errors.

• Variable Corrections:

  • Fixed issues with variable handling, especially for arrays, ensuring accurate data processing and improved runtime behavior.

Full Changelog:

• Fix source file paths
• Refactor email_alert.py for Python 2.7 compatibility
• Rollback check_process_status to run in background
• Fix local_ip_list to be GLOBAL and validate_drbd_resources_loaded
• Rollback incorrect DRBD resources validation
• Refactor watchdog process initialization
• Refactor variables for array compatibility

v2.5.0-rc

Release Notes for Version v2.5.0-rc

New Features:

• Enhanced Package Structure:

  • Refactored and updated iscsi-ha.spec to improve package organization and dependencies.
  • Introduced architecture-specific builds, changing from noarch to x86_64.
  • Improved compatibility checks for XenServer and XCP-ng during pre-installation.
  • Defined a new documentation directory macro to better manage doc files.

• New System Configuration:

  • Added an override configuration for the TGTD system for better customization and control.

Enhancements:

• Directory Structure Improvements:

  • Moved documentation files to the /usr/share/doc directory for consistency.
  • Relocated legacy install/uninstall scripts to the /usr/libexec directory.
  • Transferred various configuration files to the /etc directory, aligning with standard practices.
  • Updated paths for runtime state files and system initialization scripts to /usr/libexec and /etc/init.d.

• Script Refactoring:

  • Refactored numerous scripts for improved readability, maintainability, and error handling:
    • iscsi-cfg: Enhanced readability and maintainability by aligning with standard naming conventions, ensuring consistent quoting and formatting, and consolidating redundant logic.
    • post_version.py: Resolved functionality issues and optimized for better modularity.
    • timeout, status, log, drbd-split-brain-alert, config_manager, become_primary, fw_init, email_alert, and replug_pbd scripts: Addressed ShellCheck issues, improved modularity, and enhanced error reporting.
  • Ensured consistent formatting in all scripts, including iscsi-ha.sh and iscsi-mon, with resolved ShellCheck warnings.

ShellCheck Fixes:

A wide range of ShellCheck issues were resolved across the codebase, addressing common scripting pitfalls:

• Fixed quoting issues to prevent word splitting and glob expansion.
• Replaced legacy backticks with modern $(...) command substitution.
• Transitioned from [ p -a q ] and [ p -o q ] to well-defined constructs like [ p ] && [ q ].
• Replaced inefficient constructs like cat file | cmd with cmd < file.
• Improved handling of arrays, loops, and exit codes to align with best practices.
• Utilized safer alternatives such as pgrep, find, and grep -c for better performance and robustness.
• Resolved variable handling and formatting issues in commands like printf and tr.

Bug Fixes:

• Improved Script Compatibility:

  • Fixed ShellCheck issues across all major scripts, including deprecated syntax, missing quotes, and redundant commands.
  • Enhanced script logic to handle edge cases and improve error detection.

• Resolved Packaging Issues:

  • Updated the %files section of the RPM spec to correctly manage configuration, documentation, and application-specific files.
  • Fixed state and log directory handling with %ghost files in the RPM spec.

• Improved Initialization and Service Management:

  • Refined initialization scripts for better compatibility with service management tools.
  • Adjusted service installation logic to disable unused services (e.g., scsi-target and drbd) during package installation.

Documentation Updates:

• Man Pages:

  • Created a Linux man page for the iscsi-cfg script to improve user accessibility and guidance.

• Documentation Files:

  • Updated documentation paths and filenames for better organization and alignment with best practices.

Miscellaneous:

• Code Cleanup:

  • Removed unused scripts, such as check_disk_smart_status, to streamline the codebase.
  • Synced development support files with the ha-lizard project for consistency.

• Configuration Improvements:

  • Added pre-commit configurations and auxiliary files to enhance code formatting and enforce coding standards.
  • Introduced a devbox configuration file for streamlined development environments.

• Add roadmap for the project. by @vhsantos in #3
