Configure Server volumeClaimTemplate accessModes setting in Seldon-Core V2
Describe the bug
When trying to set an MLServer replicas
> 1 in Seldon-Core V2, I'm getting an error related to the PVC:
Multi-Attach error for volume "pvc-*****************" Volume is already exclusively attached to one node and can't be attached to another.
As I understand it's due to the fact that the pods are on different nodes and the definition of the volumeClaimTemplates for mlserver-models is defined as ReadWriteOnce by default. When I manually changing the definition to ReadWriteMany in the ServerConfig the error is gone.
To reproduce
Deploy a Server resource (I used the mlserver
serverConfig
in this case) with more than 1 replica.
** You should deploy it on a multi-node cluster
Expected behavior
Following this Slack thread, I understand I can configure the helm chart or create a custom ServerConfig. But, I think it will be valuable to have an option to configure it per Server resource
