Network File System(NFS)

Answer

  • When an NFS client mounts an NFS file system, it sends a request to the NFS server indicating which version(s) of the NFS protocol it supports
  • The server responds with the highest version number that both the client and server support
  • Related options that determine the NFS version during mount:
NFS client:
Mount option -o vers=
Configuration file /etc/nfsmount.conf
 
Storage system:
::> vserver nfs show
NFS v3: enabled/disabled
NFS v4.0: enabled/disabled
