files inside a pod stored on local-fs instead of drbd

[hpollak]

yes, i used /mnt1 instead of /mnt cause /mnt is a standard-folder and i want do be sure nothing else use it. So maybe I have something done wrong on setup.
I will resetup the nodes from scatch.
Thank you!!
Best regards

I think this is Problem Problem with microk8s so I have opened an issue there.

Started with kube-linstor i had some problems, caused on microk8s didn't assigned node-roles, so i added "node-role.kubernetes.io/master: "" " per hand to the nodes. But then the installation works fine.

Yeah, I should probably remove this from the example values 😅

"touch /mnt1/harry_dont_understand.txt

that's weird, are you sure you used /mnt1, not /mnt? Afterr applying your YAMLs I have everything fine:

$ kubectl exec -ti deploy/nginx-deployment -- df -h /mnt1
Filesystem      Size  Used Avail Use% Mounted on
/dev/drbd1011   980M  2.6M  910M   1% /mnt1

@hpollak could you link the issue here please?

UPD: Ah, found it already canonical/microk8s#2490
