feat(nvca): enable ReadWriteMany model caching for Weka and OCI FSS - #1984
balajinvda wants to merge 1 commit into
Conversation
Both are shared filesystems, so the catalog entries take the ReadWriteMany shape: one shared claim per cache handle, populated once and mounted read-only by every reader, with no derived reader PV and so no reader mount options. Enabling them makes the Helm and regular cache workflows reachable on clusters whose nvcf-sc is Weka or FSS, which is what the qualification run needs. Lustre stays off. Both catalog copies, the source chart and the vendored chart, change together and remain identical. Co-Authored-By: Balaji Ganesan <bganesan@nvidia.com>

Folded into #1969 so the mirror, the built-in catalog fallback, and the Weka/FSS enablement ship together. Closing; the branch stays for reference. |

Why
The storage capability catalog listed Weka and OCI FSS with empty access modes, so NVCA treated both as unsupported for caching and neither the Helm nor the regular model cache workflow could run on a cluster whose
nvcf-scuses them. The distributed-filesystem path is complete on main (#1334, #1434, #1516, #1564, #1565, #1580, #1593) and needs these entries on to be exercised at all. Enabling them is a data change, as the catalog was designed for.What changed
csi.weka.ioandfss.csi.oraclecloud.com:accessModes: [ReadWriteMany],readerMountOptions: []. Both are shared filesystems, so they take the ReadWriteMany shape: one shared claim per cache handle, populated once, mounted read-only by every reader, no derived reader PV.lustre.csi.oraclecloud.comstays off.deployments/nvca-operator/files/and the vendored chart underdeploy/helm/nvca-operator/. Byte-identical.TestShippedStorageCapabilityCatalogasserts the new shape for Weka and FSS and that Lustre remains empty.Customer Release Notes
Model caching is now available for Helm and container functions on clusters whose model cache storage class is backed by Weka or OCI File Storage.

Usage
The catalog ships as ConfigMap
nvcf-storage-capabilities. On a cluster that already has the operator, the same edit can be applied live to that ConfigMap; NVCA reads it per request.Testing
