I am logged into an NX4 as root and I cannot delete a filesystem.  First I couldn't delete the CIFS share to it.  I would click OK to proceed and it would just flash the browser.  I was able to unshare it by running mmc and adding computer management snap it and adding the cifs name for this NX4.  So that is done.

I can't remove the NFS export for this file system.  Same issue.  Click OK to proceed.  Otherwise click Cancel.  Well I click OK and nothing happens.

I can't delete the filesystem itself.  Same exact issue.  Is there a way to do this via command line instead since Uni sphere seems buggy?
