Can Trident use Multus on OpenShift for the storage network?
Applies to
- NetApp Astra Trident
- Red Hat OpenShift Container Platform 4.14 and later
- Clusters with a dedicated storage or NAS network separate from the pod network
Answer
No. A secondary Multus interface on trident-controller is not an officially supported Trident topology; the trident node pods using host networking is normal, and the node daemonset always runs with host networking so NFS and iSCSI use the worker NAS addresses.
Additional Information
- For multi-homed OpenShift clusters, the supported way to give the controller access to a storage or management network is
hostNetwork: trueon the TridentOrchestrator (Trident 25.10 and later) - Customize Trident operator installation
- Trident backends fail with network is unreachable
- Red Hat KB 6969174
- GitHub issue 1004
