Re-exporting your /etc/exports - how do I get a change in order of shares to take effect?
I have several NFS mount points that also have child directories also exported and I've been told that you should export the parent directories first, then the children. I've updated my /etc/exports file and ran exportfs -r on the filer but it does not look like it's taking effect if I do an exportfs to see what's currently exported. How do I get the exports in the correct order?

Was the reason for that, specified? If it was wrt order of matching, then it should not matter - ONTAP looks for the longest matching prefix to determine which export rule to apply. The docs mention that (search for 'prefix') -

So the order in /etc/exports or the exportfs display, should not matter. You can test and try to see which rule is taking effect.
Aside - you will need to be watchful about how the export permissions are laid out for the child and the parent dirs - to be sure you really have the desired checks in-effect at each level.
thanks,

Hi Jeremy I'm not sure it really makes any difference from an exports perspective. If you update /etc/exports and export what's already exported, I wouldn't expect it to change. In fact it doesn't, even if you reboot.
Now nested mounts are a totally different story. You need to mount those in order from highest to lowest.
Share and enjoy!
Peter

That's the point, I changed the export files to put the parent directories first but they don't show up that way when I do an exportfs, even after an exportfs -r. I'd expect them to now be in the same order as the new exports file.
