Manually create SMB and NFS share

Yes, In the System -> Services I click on NFS and uncheck the box Enable NFS, then APPLY.

Wait... So you're only disabling NFS, not also re-enabling it?

On my Ultra the "standard" shares are still visible when running exportfs, even if NFS is disabled (NFS button is not green). However, my share that I added by editing etc/exports and exportfs -a disappears.

That's not how it works on my Ultra 2 Plus (OS 4.2.26).

With NFS enabled in Frontview:System:Standard File Protocols, I created a share from within Frontview and enabled NFS access to it. That automatically added it to /etc/exports and made it appear in the exportfs output, as expected:

NAS2:/# cat /etc/exports
"/nfstest" *(insecure,insecure_locks,ro,sync)
NAS2:/#
NAS2:/# exportfs
/c/nfstest      <world>
NAS2:/# 

Then I disabled NFS from Frontview. This cleared the exportfs output (note that this behavior is different from what you reported):

NAS2:/# exportfs
NAS2:/#

Then I edited /etc/exports manually to add a new share:

NAS2:/# cat /etc/exports
"/nfstest" *(insecure,insecure_locks,ro,sync)
"/nfstest_manual" *(insecure,insecure_locks,ro,sync)
NAS2:/#

Exporting the shares, even with the NFS server stopped, made them both show up in the exportfs output (I didn't expect this):

NAS2:/# exportfs -a
exportfs: /etc/exports [1]: Neither 'subtree_check' or 'no_subtree_check' specified for export "*:/nfstest".
  Assuming default behaviour ('no_subtree_check').
  NOTE: this default has changed since nfs-utils version 1.0.x

exportfs: /etc/exports [2]: Neither 'subtree_check' or 'no_subtree_check' specified for export "*:/nfstest_manual".
  Assuming default behaviour ('no_subtree_check').
  NOTE: this default has changed since nfs-utils version 1.0.x

NAS2:/#  exportfs
/c/nfstest_manual
                <world>
/c/nfstest      <world>
NAS2:/#

Re-enabling NFS from within Frontview didn't change anything; exportfs still shows both shares:

NAS2:/# exportfs
/c/nfstest_manual
                <world>
/c/nfstest      <world>
NAS2:/#

Disabling NFS from within Frontview makes them both disappear from the exportfs output (again, this is not the behavior that you reported):

NAS2:/# exportfs
NAS2:/#

And re-enabling NFS brings them both back:

NAS2:/# exportfs
/c/nfstest_manual
                <world>
/c/nfstest      <world>
NAS2:/#

I don't know why your system apparently behaves differently from mine, but I'm also not too sure that it matters: Do we really care whether a directory appears in the exportfs list while the NFS server is disabled? The important thing is that it's in the exportfs list while the NFS server is running, right?
