From bb7ca93c184eb98cfacb62da92c95d038ecf227c Mon Sep 17 00:00:00 2001 From: rcourtman Date: Sun, 9 Nov 2025 16:36:33 +0000 Subject: [PATCH] feat: Add mdadm RAID monitoring support for host agents Implements comprehensive mdadm RAID array monitoring for Linux hosts via pulse-host-agent. Arrays are automatically detected and monitored with real-time status updates, rebuild progress tracking, and automatic alerting for degraded or failed arrays. Key changes: **Backend:** - Add mdadm package for parsing mdadm --detail output - Extend host agent report structure with RAID array data - Integrate mdadm collection into host agent (Linux-only, best-effort) - Add RAID array processing in monitoring system - Implement automatic alerting: - Critical alerts for degraded arrays or arrays with failed devices - Warning alerts for rebuilding/resyncing arrays with progress tracking - Auto-clear alerts when arrays return to healthy state **Frontend:** - Add TypeScript types for RAID arrays and devices - Display RAID arrays in host details drawer with: - Array status (clean/degraded/recovering) with color-coded indicators - Device counts (active/total/failed/spare) - Rebuild progress percentage and speed when applicable - Green for healthy, amber for rebuilding, red for degraded **Documentation:** - Document mdadm monitoring feature in HOST_AGENT.md - Explain requirements (Linux, mdadm installed, root access) - Clarify scope (software RAID only, hardware RAID not supported) **Testing:** - Add comprehensive tests for mdadm output parsing - Test parsing of healthy, degraded, and rebuilding arrays - Verify proper extraction of device states and rebuild progress All builds pass successfully. RAID monitoring is automatic and best-effort - if mdadm is not installed or no arrays exist, host agent continues reporting other metrics normally.
