Symptoms

When mounting a NFS datastore, it mounts but is not accessible.

When attempting to check the contents of the NFS datastore you see this error:

[root@ netApp_NFS]# pwd
/vmfs/volumes/netApp_NFS
[root@ netApp_NFS]# ls
ls: .: Permission denied

Unmounting and re-mounting the datastore with esxcfg-nas command does not resolve this issue.

In the vSphere Client, you see error similar to:

error during configuration of the host. Cannot open volume

or

error: An error occurred during host configuration

In the vmkernel or messages log files, you see an entry similar to:

NFS: 107: Command: (mount) Server: (nfsserver.vmware.com) IP: (11.111.11.111) Path: (/vol/UATNFS1) Label: (UATNFS1) Options: (None)

In the hostd.log log file of the ESX host, you see entries similar to:

Cause

This issue occurs due to an incorrect configuration value for the qtree security type on the NetApp storage array. The qtree permissions on the NetApp storage device are set to NTFS or Mixed style (also known as UNIX).

Resolution

To resolve this issue, check and correct the setting of the qtree security type value for the NetApp volume in question.

Ensure that the qtree security type value is set to Unix rather than NTFS.

This setting can be set for each individual NFS export, depending on the configuration of the NetApp.

For more information, see the NetApp whitepapers TR-3428: NetApp and VMware Virtual Infrastructure 3 Storage Best Practices and TR-3749: NetApp and VMware vSphere Storage Best Practices.

Note: The preceding links were correct as of December 16, 2014. If you find a link is broken, provide feedback and a VMware employee will update the link.

To check the qtree permissions, run this command from the CLI on NetApp:

qtree status

You see output similar to:

Volume Tree Style Oplocks Status
-------- -------- ----- -------- ---------
vol0 unix enabled normal
ProdLuns unix enabled normal
ProdRDM1 unix enabled normal
<server> ntfs enabled normal

This sample output indicates that the volume is set to NTFS style.

Note: Enabling CIFS can change the qtree type to NTFS on existing datastores. After enabling CIFS, be sure to change the qtree permission back to UNIX.

To resolve this issue, run this command from the NetApp CLI to set the qtree permission to UNIX:

qtree security /vol/<volume> unix

To change the qtree permission using the NetApp GUI:

Click Volumes > Qtrees > Manage.

Select the volume and change the permission from NTFS to UNIX.
