I have Macbook Pro 2015, running El Capitan 10.11.1 and I am having issues with NFS mounts. I also have an Android TV Box and it mounts NFS without any issues, so I guess the issue is with my laptop. Here is the NFS config(/etc/exports):


When I run showmount:

$ showmount -e rpi

Exports list on rpi:

I mount from Finder > Go > Connect to Server and enter: nfs://rpi/media/mypassport

This mounts my NFS drive, however sometimes it disconnects and I am not able to remount again. I have to restart my machine and keep trying till it doesn't disconnect.

When I ls into /Volumes I get following error:

$ ls

ls: mypassport: Device not configured
Macintosh HD

Whats the issue here? Why it keeps unmounting or gets disconnected? And how do I remount without restarting?

  • Let's take a look at your logs on both machines. On your Mac, issue the command syslog | grep -i nfs. I don't know what you are running as your host, but you can try the same command there. If you see anything, rerun the command and append | pbcopy to the command so it outputs to your clipboard for pasting here

  • NFS is being run in Raspberry Pi and it uses Raspibian Jessie. Let me post logs

  • I don't know whats the syslog equivalent for Pi, so I posted output from dmesg. Here is the log from my laptop - link and here is the link to that of Pi - link

  • Are you running a firewall on your Mac? If so, turn it off

  • No, firewall is already off.

Restart NFS without Rebooting

Issue the following command in Terminal:

sudo nfsd restart

This has the effect of stopping the NFS daemon, starting it back up, rereading your config and processing what's in your /etc/exports

OS X Disconnecting from NFS

Try this:

find . -name ._* | xargs rm on the R-Pi in the directory that gets mounted. That will remove any of the hidden "_filename" files that OS X creates when going through a directory

Based on this Apple Support Forum with similar symptoms: https://discussions.apple.com/thread/2733032?start=0&tstart=0

  • It disconnects in one or two minutes. For example, I have mounted the drive and using chrome or anything else, the mac would be still on and not going to sleep. And yet it disconnects.
