Symptoms
An error was generated when trying to create an NFS share.
The error message states that a share with the specified name already exists in the NAS server, even though it did not appear to exist.
There are two scenarios that can result in this error when attempting to create a share.
Scenario (1):
A subfolder is already using a shared name that is the same as the file system name.
And
An attempt was made to create a new share directly under the file system.
Scenario (2):
An NFS share with a name different from the file system name is created directly under the file system.
And
An attempt was made to create an NFS share with the same name as the file system name in a subfolder.

An NFS share with a name different from the file system name is created directly under the file system.
And
An attempt was made to create an NFS share with the same name as the file system name in a subfolder.
Cause
When an NFS share is created, it is accessible by both the share name and the local path.
If a share with a file system name exists in a subfolder, creation of the share directly under the file system fails. This is because the local path (/filesystem_name) entry is duplicated when creating a share directly under the file system.
If a share is created directly under the file system, it cannot have the same name as the file system name in a subfolder. This is because there is already an entry for /filesystem_name.
This behavior is functioning as designed.

Resolution
Avoid creating an NFS share with the same name as the file system in a subfolder.
Additional Information
Scenario (1):
Step 1: Share /fs_name/fs_name with a share name of 'fs_name'
Share Name = /fs_name
Local Path = /fs_name/fs_name
Step 2: Share the file system /fs_name with the share name of 'test'
Share Name = /test
Local Path = /fs_name <=== Error 0x900a008, share name already exists
Scenario (2):
Step 1: Share '/fs_name' with a share name of 'test'
Share Name = /test
Local Path = /fs_name
Step 2: Share '/fs_name/fs_name' with a share name of '/fs_name'
Share Name = '/fs_name' <=== Error 0x900a008, share name already exists
Local Path = /fs_name/fs_name
