Update 16/10/2014: it looks like all this continues to work in Yosemite as well as Mavericks
Until recently I’d been using Snow Leopard on my MacBook Pro. I also have a wee NAS, and had configured it to share its folders via NFS. I’d mounted these on my Mac using the fairly obscure NFS menu items in Disk Utility.
But after upgrading to Mavericks, my NFS mounts had disappeared. My Google-fu didn’t turn up anything that looked like user-level documentation on this issue, so I put on my UNIX hat and went rummaging in /etc.
What we’re dealing with here is the automounter, aka autofs. I know how this works on older UNIXes and Linux, but OS X does things differently. I found some information from 2009 which seems to still be accurate:
Here’s how I got my mounts working again.
First, I edited /etc/auto_master to add a line for my NAS mount points:
What this means is, “for directories under /nas, consult the file /etc/auto_nas to see how to mount them”. I added this before the final /- line, which I believe is a wildcard, but I’m not sure whether order is significant in this file (the linked document would probably answer that).
So secondly, I added the file auto_nas:
music storage.local:/nfs/music data storage.local:/nfs/data
This lets me access the music and data folders on my NAS from my Mac as /nas/music and /nas/data respectively.
Finally, I told the automounter that I’d changed its configuration:
sudo automount -vc
After that I was able to access my network data again, happy times.
