StatefulSet replicas on a node has shared memory

Question

I am trying to deploy a stateful set of IPFS replicas on three Kubernetes worker nodes (based on this repo). The first three replicas work properly, but when it comes to the fourth one, it appears that the persistentVolumeClaims point to the shared physical memory. Therefore, the fourth node cannot acquire the lock. What would be the standard way to deploy many IPFS replicas in Kubernetes?

The fourth node printed the following log:

08:44:19.785 DEBUG   cmd/ipfs: config path is /data/ipfs main.go:257
08:44:19.785  INFO   cmd/ipfs: IPFS_PATH /data/ipfs main.go:301

Error: ipfs daemon is running. please stop it to run this command

Here is the yaml file for the stateful set:
