研究方向

首先針對 SeaweedFS 重現 ObjectStore 和 Cluster 設定，然後檢查 WAL Archive request 中回報的 barman-cloud-wal-archive 失敗。完成標準是 WAL 封存能夠成功上傳至設定的目的地，且不會出現 exit status 4 錯誤。

由索引模型根據 Issue 內容生成。

描述

bug

When creating ObjectStore CR that points to SeaweedFS s3 objectstore it starts uploading the wal archives, makes a .upload directory, but then I got the error:
{"level":"error","ts":"2025-12-16T10:46:23.075022375Z","msg":"Error while handling GRPC request","logging_pod":"postgresql-1","info":{"Server":{"Client":{"Client":{}},"InstanceName":"postgresql-1","SpoolDirectory":"/controller/wal-restore-spool","PGDataPath":"/var/lib/postgresql/data/pgdata","PGWALPath":"/var/lib/postgresql/data/pgdata/pg_wal"},"FullMethod":"/cnpgi.wal.v1.WAL/Archive"},"error":"unexpected failure invoking barman-cloud-wal-archive: exit status 4","stacktrace":"github.com/cloudnative-pg/machinery/pkg/log.(*logger).Error\n\t/go/pkg/mod/github.com/cloudnative-pg/[email protected]/pkg/log/log.go:125\ngithub.com/cloudnative-pg/cnpg-i-machinery/pkg/pluginhelper/http.(*Server).Start.logFailedRequestsUnaryServerInterceptor.func2\n\t/go/pkg/mod/github.com/cloudnative-pg/[email protected]/pkg/pluginhelper/http/grpc.go:53\ngoogle.golang.org/grpc.NewServer.chainUnaryServerInterceptors.chainUnaryInterceptors.func1\n\t/go/pkg/mod/google.golang.org/[email protected]/server.go:1234\ngithub.com/cloudnative-pg/cnpg-i/pkg/wal._WAL_Archive_Handler\n\t/go/pkg/mod/github.com/cloudnative-pg/[email protected]/pkg/wal/wal_grpc.pb.go:196\ngoogle.golang.org/grpc.(*Server).processUnaryRPC\n\t/go/pkg/mod/google.golang.org/[email protected]/server.go:1431\ngoogle.golang.org/grpc.(*Server).handleStream\n\t/go/pkg/mod/google.golang.org/[email protected]/server.go:1842\ngoogle.golang.org/grpc.(*Server).serveStreams.func2.1\n\t/go/pkg/mod/google.golang.org/[email protected]/server.go:1061"}

However, with awscli I can reach the bucket and can upload objects

Objectstore definition
`
apiVersion: barmancloud.cnpg.io/v1
kind: ObjectStore
metadata:
name: azure-backup-store
namespace: postgres
spec:

Base configuration for Barman Cloud to connect to Azure

Cluster definition:
`
apiVersion: postgresql.cnpg.io/v1
kind: Cluster
metadata:
name: postgresql
namespace: postgres
spec:

plugins:

    parameters:

bootstrap:
initdb:
database: authentik

enableSuperuserAccess: true

`

I also tried other options, and all of them worked except for the Barman Cloud Plugin, which drops an error.
