When there are two sets of storage in a Kubernetes cluster, one is Ceph and the other is OpenEBS, what if some applications use Ceph storage and others use OpenEBS storage when utilizing Liqo? #2642

I think you're going to need to point your applications to the specific persistent volumes you would need then to depend on. However, I don't think OpenEBS indipendantly support multi-clusters like ceph does. With open ebs you're going to have to implement some other tooling such as Portworx.

Thank you for your reply.

What I mean is that after setting up Liqo, there will be a virtual Storage Class Liqo, but my cluster has two real Storage Classes, and Liqo will only use the default real Storage Class, the other one will not be used unless the other is set as the default real Storage Class. This operation is not very good, so there should be a rule setting to allow the virtual Storage Class liqo to choose the real Storage Class.
