Issue with PVC Multi-Attach Error in Kubernetes with NetBox Housekeeping Pod

[AruPersia]

Hi,

We are running NetBox in a Kubernetes environment with Longhorn as the storage backend. We are encountering a multi-attach error with a PersistentVolumeClaim (PVC) (core-netbox-media), which is already being used by two pods (core-netbox-564bb575ff-ws7jp and core-netbox-worker-5889c8576f-5gd8f). When we try to start a third pod (core-netbox-housekeeping), it gets stuck in the ContainerCreating state due to the RWO (ReadWriteOnce) access mode restriction, as the volume is already attached to two other pods.

Is there a known solution or recommended approach for handling this type of volume sharing issue in NetBox's Kubernetes deployment? Any advice or suggestions would be greatly appreciated!

Thanks in advance.

This alarm is firing in my k8s cluster with 3 nodes and longhorn setup as block storage:

pod/core-netbox-housekeeping-28856160-ldd9c in namespace netbox-core on container netbox-housekeeping has been in waiting state for longer than 1 hour.

kubectl describe pod core-netbox-housekeeping-28856160-ldd9c:
