Problem with CephFS NFS export used with VMware vSphere Cluster

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello friedns,

please help me. I’m trying to use CephFS with NFS export behind NFS Ingress Service. We are running 16.2.7 (dd0603118f56ab514f133c8d2e3adfc983942503)
pacific (stable)

Everything works fine until We try to mount datastore to multiple ESXi hosts (HPE-ESXi-6.5.0-Update2-iso-preGen9-650.U2.9.6.7.1) with vCenter (7.0.1).

My setup:

CephFS -> vSphere with subvolumes Public & Private

NFS service on three nodes (10.99.112.[1-3]) with service like: 

service_type: nfs
service_id: vSphere
placement:
  label: nfs
spec:
  port: 12345

This is working fine.

Then Ingress for NFS service to get one IP to connect from clients like: 

service_type: ingress
service_id: nfs.vSphere
placement:
  label: nfs
spec:
  backend_service: nfs.vSphere
  frontend_port: 2049
  monitor_port: 9000
  virtual_ip: 10.99.112.62/26


And NFS export like:

Access Type            RW 
CephFS Filesystem vSphere 
CephFS User          nfs.vSphere.1 
Cluster                    vSphere 
NFS Protocol          NFSv4 
Path                        /volumes/Private 
Pseudo                   /ceph 
Security Label 
Squash                  no_root_squash 
Storage Backend  CephFS 
Transport               TCP, UDP

Till this point is everything working as expected, but when We want to add new Datastore to ESXi hosts within cluster like:

Name  Ceph-NFS
Folder  /ceph
Server 10.99.112.61

it will add New Datastore to every one host like:

ESXi1 -> Ceph-NFS
ESXi2 -> Ceph-NFS(1)

what is strange for me. We want to share one NFS export like Ceph-NFS across multiple hosts and not create multiple datastores. Is there somebody who is using NFS with vSphere cluster to help us where can be problem ?

Thank you.
