NFS mount issue: volume can mount but not the folder underneath

[co5905000]

Our Linux admin can mount the volume and see the folders:

mount dcnas02-nfs:/vol/livesiteprodslgdc /mnt
[root@slglvmo7 ~]# ll /mnt
total 52
drwxrwxrwx 12 nobody nobody  4096 Mar 23  2017 cache
drwxrwxr-x   8  nobody nobody   40960 Nov 13 16:45 content
drwxrwxr-x   3  nobody nobody   4096 Jul 27  2016 library

However, he cannot mount the folder:

umount /mnt
[root@slglvmo7 ~]# mount dcnas02-nfs:/vol/livesiteprodslgdc/content   /mnt
mount.nfs: access denied by server while mounting dcnas02-nfs:/vol/livesiteprodslgdc/content

From my perspective we only export the volume and the export rules apply to this:

GRCLNAS::> export-policy  rule show -vserver dcnas02-nfs  -policyname transition_export_policy_15
             Policy          Rule    Access   Client                RO
Vserver      Name            Index   Protocol Match                 Rule
------------ --------------- ------  -------- --------------------- ---------
dcnas02-nfs  transition_export_policy_15
                             1       nfs      slglvmf5.internal.    sys
                                              xxxxx.com
dcnas02-nfs  transition_export_policy_15
                             2       nfs      0.0.0.0/0             sys
dcnas02-nfs  transition_export_policy_15
                             3       cifs     0.0.0.0/0             any

The first command allows the volume to be mounted but can you actually access those subfolders once mounted i.e. Cd into them? What security style is set on the volume? Can you access these same volumes through a cifs share and if so does access work there?

If it a permissions issue then the following command usually helps: vserver security file-directory show -vserver <vserver name> -path <path>

Hi, thanks for your reaponse. I subsequently realised that the volume had qtrees with export policies applied to them:

Once I altered the applicable export policy the Linux guys were able to access the folder.

thanks Rob
