Hello.
I have a MongoDB 7 with 3 nodes in a replicaset configuration, but while trying to configure PBM to interact with a GCS bucket, I am getting the below error:
mongodb-replica-set:
- 10.0.1.11:27017 [S]: pbm-agent [v2.10.0] FAILED status:

I am running PBM version 2.10 on Rocky Linux 9 in Google Cloud:
Version: 2.10.0
Platform: linux/amd64
GitCommit: 92dfac319381e7861d6958733a3a46d2e2f7a5a1
GitBranch: release-2.10.0
BuildTime: 2025-06-23_09:47_UTC
GoVersion: go1.23.8
My “pbm_config.yaml” file looks like this:
storage:
type: gcs
gcs:
bucket: <bucket-bkp>
prefix: mongodb
credentials:
clientEmail: <service-account>
privateKey: <path>/pbm_gcs.pem
backup:
priority:
"10.0.1.11:27017": 0.5
"10.0.1.12:27017": 0.5
"10.0.1.13:27017": 1.0
My PEM file seems to be on the right format, as obtained directly from “gcloud iam service-accounts keys” command
Any insights on why this is failing?
Thanks a lot.
