Applies to

  • ONTAP 9
  • NTFS security style volume
  • NFSv3 and NFSv4.x

Issue

  • NFS mount of an NTFS volume hangs, times out, or getting error "permission denied" using root user:

mount.nfs: timeout set for Mon May  6 13:21:35 2024
mount.nfs: trying text-based options 'proto=tcp,soft,timeo=300,retrans=2,actimeo=1,vers=4,addr=10.x.x.12,clientaddr=10.x.x.11'
mount.nfs: mount(2): Permission denied
mount.nfs: access denied by server while mounting 10.x.x.12:/dir1/dir2

  • Export policy rules grant the client read and write access to the volume:
cluster1::> vserver export-policy check-access -vserver vs1 -client-ip 10.22.32.42 -volume vol4 -authentication-method sys -protocol nfs3 -access-type read-write
