Expected behavior

I deployed a minio 5.0.11 cluster in k8s by helm, and I want to continuously synchronize the data of this minio cluster to another minio 5.0.11 cluster of the same version through mc mirror --watch.

Actual behavior

mc mirror --watch minio-source minio-dest During synchronization, an error is reported: mc: Failed to perform mirroring readObjectStart: expect { or n, but found <, error found in #1 byte of ...

Steps to reproduce the behavior

mc mirror --watch minio-source minio-dest

mc --version

mc version RELEASE.2023-12-02T02-03-28Z (commit-id=f5f7147b9ec4cf78eb67f1cdc91b63d191852e6a) Runtime: go1.21.4 linux/amd64 Copyright (c) 2015-2023 MinIO, Inc. License GNU AGPLv3 https://www.gnu.org/licenses/agpl-3.0.html

System information

Is it because minio version 5.0.11 can't support the mc mirror --watch command?

whats your load balancer?

joh-zhang commented 11 months ago

I didn't use K8S's load balancer, and the above synchronization operation was done through K8S's SVC exposing the minio port

helm install minio-source --set persistence.enabled=true --set accessKey=minio --set secretKey=minio123 --set persistence.size=1Gi --set resources.requests.memory=500Mi --set persistence.storageClass=minio-nas --set mode=distributed,replicas=4 .

Here's how I installed the minio cluster @harshavardhana

k8s service export does not support proper event stream payload properly.

You need to use a real load balancer like nginx to get that support.
