When I start my elasticsearch cluster's pod in kuberntes(v1.15.2),pods log give this error:

I started 3 pod and each pod have it's own data folder(mount by 3 PV and 3 PVC).It is impossible to make multi node read and write one data folder.So how could this happen, should I change the NFS folder permission?
