I am using the Dremio’s Helm Chart V2 to deploy the Dremio cluster.
Ref: dremio-cloud-tools/charts/dremio_v2 at master · dremio/dremio-cloud-tools · GitHub

GCS storage plugin is supported in Dremio starting from 16.0 version.
Could you please mention what Dremio version was deployed using Helm Chart?

Hello,

I am using the 15.7.0 version. I see that the dremio/dremio-oss image doesn’t have the 16.0.0 version available at the moment.
