From b2b301332f0e9128fac118364b8ecc5f807a280e Mon Sep 17 00:00:00 2001 From: Christoffer Martinsson Date: Sun, 23 Nov 2025 21:43:34 +0100 Subject: [PATCH] Fix storage display showing missing total usage data MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The structured data bridge conversion was only converting individual drive metrics (temperature, wear) and filesystem metrics, but wasn't generating the aggregated total usage metrics expected by the storage widget (disk_{drive}_total_gb, disk_{drive}_used_gb, disk_{drive}_usage_percent). This caused physical drives to display "—% —GB/—GB" instead of actual usage statistics. Updated the bridge conversion to calculate drive totals by aggregating all filesystems on each drive: - total_used = sum of all filesystem used_gb values - total_size = sum of all filesystem total_gb values - average_usage = (total_used / total_size) * 100 Now physical drives like nvme0n1 properly display total usage aggregated from all their filesystems (e.g., /boot + / = total drive usage).
