What’s the full path to these pvc’s?

/docker/lib/longhorn/replicas/pvc-48586aa6-cc79-40e0-94b1-bf20e48ffa72-01eb5a76
where path 
Path: /docker/lib/longhorn/
was added as a disk
the rest of those volume have prefix 
/docker/lib/longhorn/replicas/NAME_OF_PVC+SUFFIX

So I think you should use a dedicated storage space for Longhorn and not what seems to be the sys disk
Also why are you still using the docker container runtime?

docker
is confusing
Also why are you still using the docker container runtime?

What Kubernetes flavor are you on? K0s, K3s or something third?
It’s totally confusing that 
docker
is part of the folder name.

Use 
containerd
… the docker shim have been deprecated in newer version of Kubernetes for some time.
But, the replicas there are to be expected. The default conf. setting of Longhorn is to have 3 replicas per PVC

ah, and even If I have single node it will create 3 x replicated directorieries on single node?

You can control the default in the storage class backing your pvcs … 
numberOfReplicas
is what you’re looking for
