However on A nfs was certainly stopped, but a start and restart gave: [root@A ~]# service nfs start Starting NFS services: [FAILED] Starting NFS quotas: [ OK ] Starting NFS daemon: [ OK ] Starting NFS mountd: [ OK ] [root@A ~]# service nfs restart Shutting down NFS mountd: [ OK ] Shutting down NFS daemon: [ OK ] Shutting down NFS quotas: [ OK ] Shutting down NFS services: [ OK ] Starting NFS services: [FAILED] Starting NFS quotas: [ OK ] Starting NFS daemon: [ OK ] Starting NFS mountd: [ OK ] [root@A ~]# What would be causing this?
