Hi together,

I am trying to setup k8ssandra on my laptop to evaluate and start developing.
I followed so far the steps listed in the documentation and also saw the hints on resource requirements. My laptop is a standard lenovo thinkpad with 16GB RAM and a I7 cpu.
For k8ssandra installation, I am starting a Vagrant VirtualBox with 16GB RAM and 8 CPUs.
Except for stargate and reaper pod, everything is running as expected. Just these two just don’t want to. What puzzles me, is that I cannot find an error in the stargate’s log.
The reaper says, “no datasource available” which I think is related to the crashed stargate pod. The only point that comes to my mind is the warning about rlimi memlock. However, from what I saw, kubernetes currently provides no way to pass a ulimit option.

Do you have a tip for me?

Please find below some dumps. I apologize for the plain text pasting here. If there is a preferred way to pass large logs, please let me know.

It’s not readily obvious to me what the problem is. Could you please post the following?




    

$ kubetctl get nodes
$ kubectl get pods
And a kubectl describe on the Reaper pod please?
              
Hi guys,
thank you so much for your quick responses. I am happy to provide required logs.

get pods coming…
              
I suspect there could be some schema disagreements due to Stargate starting at the same time Reaper performs the schema migration.
Could you uninstall your Helm release and redeploy K8ssandra with 0 Stargate replica, and once everything is up and running (including Reaper), modify your Helm values to add 1 Stargate replica and upgrade your release? helm upgrade <release-name> k8ssandra/k8ssandra -f <values-file.yaml>
              
Hi Alex,

seems you were right regarding the stargate. I upgraded now the installation. Unforunately, stargate and reaper are still restarting.

Here is the “get pods” result:

The log of stargate looks pretty much the same. For me it seems, the process is somehow terminated. No clue…
              
Hey guys,

I tried to start stargate with 512M heap, but without effect.

Summarized, starting k8ssandra without stargate works like cheers. At least from what I can observe from “get pods”.

At the moment I start stargate, reaper and stargate are in a CrashBackLoop.

I did a dmesg. It is lots of stuff (I’ve cut a bit from the top). I wasn’t able to identify anything there. Maybe it helps you.

Hmmmm, doesn’t look like it was OOM killed. Have you checked the logs in the server-system-logger container of k8ssandra-dc1-default-sts-0?




    

By chance have you tried bringing up stargate and then reaper once everything is settled?
Another option is increasing the probe delays for stargate. Depending on the size of your schema and resource constraints stargate might not be able to settle gossip in time.
