…pacity display OCPBUGS-114891 Prometheus API returns metric values as strings (e.g. "1234567890"), but humanizeBinaryBytes expects numeric input. Since the migration from global isFinite to Number.isFinite, string values are no longer coerced and instead produce "0 B". Convert Prometheus values to numbers at extraction and use explicit null checks (usedMetrics != null) to correctly handle zero as a valid used-bytes value. Also adds round-trip tests verifying the full convertToBaseValue → humanizeBinaryBytes pipeline for all K8s storage unit formats (Ki through Ei, and decimal k/M/G/T).

OCPBUGS-114891 The Used row in PVC details was displaying usedCapacity.string which forces totalCapacity.unit, causing small values (e.g. 512 MiB on a 1 TiB volume) to round to "0 TiB". Use humanizeBinaryBytes(usedMetrics) without a preferred unit so it auto-scales to the appropriate unit. The donut chart retains the forced-unit value for visual consistency.

Analysis / Root cause:
The PVC detail page extracts Prometheus metric values (
kubelet_volume_stats_used_bytes) as raw strings from the API response (response?.data?.result?.[0]?.value?.[1]). The Prometheus API returns[timestamp, value]tuples where the value is always a string (as typed inPrometheusValue = [number, string]).These string values were passed directly to
humanizeBinaryBytes(), which callshumanize()internally. After the migration from the globalisFinite()toNumber.isFinite()(commit bd12d57), string values are no longer coerced to numbers —Number.isFinite("1234567890")returnsfalse— causing the function to treat them as invalid and return"0 B"instead of the correct humanized capacity.The list view was unaffected because it already converts Prometheus values via
Number(item?.value?.[1])when building the metrics map.Solution description:
Number(), consistent with how the list view already handles it.usedMetrics ?) with explicit null checks (usedMetrics != null && Number.isFinite(usedMetrics)) to correctly treat0as a valid used-bytes value.usedCapacity.stringinstead of callinghumanizeBinaryBytes(usedMetrics)a second time.convertToBaseValue→humanizeBinaryBytes) covering all K8s storage unit formats (Ki through Ei, multi-unit equivalences like 3072Gi → 3 TiB, and decimal units k/M/G/T).Screenshots / screen recording:
Test setup:
Navigate to Storage → PersistentVolumeClaims → select a PVC with active Prometheus usage data. Verify the "Used" capacity field displays the correct humanized binary value (e.g., "1.5 GiB") instead of "0 B".
Test cases:
Browser conformance:
Additional info:
The capacity column in the PVC list view was already correct — it uses
convertToBaseValue()which returns a proper number, thenhumanizeBinaryBytes()which correctly displays binary units (KiB, MiB, GiB, TiB). The round-trip tests confirm this pipeline: e.g.,"3Ti"→3298534883328→"3 TiB".Summary by CodeRabbit
