CIFS clients usually don't try to reconnect and do exactly the same
thing after a failure. They know better - after all, the product was
developed by Microsoft.

Subject: RE: Enabling/Disabling NFS shares

I think it was useful when we entered a crash loop because of a bug in
NFS. Disabling a share prevents a client from connecting and crashing
the system. Since the occurrences of NFS crash loops became much less
frequent, the command lost most of its usefulness.

(I think we should preserve it, since when we will go to systemx we are
bound to have some crash loops. :-) )

Subject: Enabling/Disabling NFS shares

This question is in the context of SystemX but about the current
product.

We have a command to enable/disable NFS shares but not one for CIFS
shares.  "nfs disable share [all | PATHNAME]"

Does anyone ever use these commands given that they do not prevent CIFS
users from connecting and CIFS has no equivalent?  I'm trying to
determine whether to preserve the functionality in SystemX given the
limited value.

Unless I hear otherwise, this is going away in SystemX.
