Hi, it’s strange. I can’t reproduce this issue. Try deleting this pod with PVC to force reinitit it from scratch.

thank you for the suggestion, i tried that but unfortunately still have the same issue.

crashing a reboots shortly after

I noticed a few strange logs in the pod that maybe the cause issues?

if i remove rs2 im able to get a healthy and ready mongodb cluster, but for whatever reason when i readd rs2 the cluster is degraded and 1 or more rs2 pods are crashing and rebooting

5

Do you have data in your cluster?

7

There is no data in the cluster, its all fresh/new

8

Maybe the node that is used for rs2-2 has some connectivity problems..

I think I might have figured it out.

I was previously using the image with tag: 8.0.4-1-multi to support r7g EC2 instance types (Graviton/ARM). After fully deleting the cluster—along with any leftover volumes—and updating the image to tag: 8.0.4-2 (which no longer has a -multi variant), everything started working again on the same EC2 instance types.

@Kay_Khan good news. Thank you for the update.

11

Yes it is good news, although im unsrue why i dont need to specify the -multi variant of the image given that im running on r7g large which is arm based ? do you have any ideas?

12

As you can see https://hub.docker.com/r/percona/percona-server-mongodb/tags?name=8.0.4-1
8.0.4-1 baced on linux/amd64. Maybe one of your nodes based on and…

13

all of our nodes are r7g arm based
