I’m having issues with Longhorn v1.2.3 prepping the filesystem of a Kafka workload. I’m seeing

exit 32

when

mount … ext4

is being executed …. and I see this err. in the

csi-plugin

Pod

on the worker node where Longhorn is having the issue.

Mounting command: mount
Mounting arguments: -t ext4 -o defaults /dev/longhorn/pvc-77efeb41-63ad-43f6-8cc0-e67b2e820aad /var/lib/kubelet/plugins/kubernetes.io/csi/pv/pvc-77efeb41-63ad-43f6-8cc0-e67b2e820aad/globalmount
Output: mount: /var/lib/kubelet/plugins/kubernetes.io/csi/pv/pvc-77efeb41-63ad-43f6-8cc0-e67b2e820aad/globalmount: wrong fs type, bad option, bad superblock on /dev/longhorn/pvc-77efeb41-63ad-43f6-8cc0-e67b2e820aad, missing codepage or helper program, or other error.

Suggestions are cherished …. thank you very much.

Did you find the same log in csi-plugin? And is volume attached to the same node with workload? Could you provide the support bundle?

Yes there's exactly the same log in the csi-plug-in. Nope we don't use replica balancing to the same nodes where the workload is necessarily. Could that be it? I'll provide the bundle
