19-20: Consider nil safety for lookup results.The lookup for disks could return nil. Consider adding a
withstatement to handle this case gracefully:-{{- range (lookup "disks" "" "").items }} +{{- with (lookup "disks" "" "") }} +{{- range .items }}
Line range hint
1-27: Architectural improvement: Kubernetes-native approach.The shift from client-based disk discovery to using
lookupfunctions aligns well with Kubernetes-native patterns. This change:
- Reduces complexity by eliminating client dependencies
- Improves reliability by using Kubernetes' resource model
- Makes the system more declarative
Consider documenting:
- The expected resource structure for disks and system disks
- Error handling expectations when resources are missing
- The migration path for existing deployments

2-3: LGTM! Verify lookup behavior in different contexts.The change to use
lookupfor system disk information is clean and follows Helm best practices. However, sincelookupreturns nil when the resource doesn't exist, ensure proper handling of missing system disk information.Run this script to verify the lookup behavior:
✅ Verification successful
Lookup implementation is safe and follows best practices
The template safely handles missing system disk scenarios through Helm's
withblock, which gracefully returns an empty string when the lookup fails. The empty result is properly quoted in all usage locations, making it a valid configuration value.🏁 Scripts executed

💡 Codebase verification
WWID filtering may unintentionally exclude valid disks
The current template only displays disks with WWIDs, but there's no documentation or code indicating this is a requirement. This filtering could exclude valid local disks that don't have WWIDs assigned. Consider:
- Removing the WWID condition to show all discovered disks
- If WWID filtering is intentional, document this requirement
🔗 Analysis chain
Verify WWID filtering requirement.
The template only displays disks with WWIDs. This might exclude valid disks that don't have WWIDs. Consider:
- Whether this filtering is intentional
- If there are use cases for disks without WWIDs
Run this script to check for disk entries without WWIDs:
