enable noatime

[hehe299792458]

I've managed to enable the noatime command for one of my drives, the Macintosh HD drive "/", but not for my data drive "/Volumes/Data". Is there anyway I could enable it for the second drive as well?

I used this command to enable noatime for the first drive:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>com.my.noatime</string>
<key>ProgramArguments</key>
<array>
<string>mount</string>
<string>-vuwo</string>
<string>noatime</string>
<string>/</string>
<string>/Volumes/Data</string>
</array>
<key>RunAtLoad</key>
<true/>
</dict>
</plist>

I have no idea how the code works, but I tried adding in "/Volumes/Data" string, but it didn't seem to do the trick.

Now, I see this:

/dev/disk0s2 on / (hfs, local, journaled, noatime)
devfs on /dev (devfs, local, nobrowse)
/dev/disk0s4 on /Volumes/Data (hfs, local, journaled)

You give so little information about your config, I am going to go ahead and assume that /Volumes/Data is actually a separate drive.

Each hard drive will havea mount plist file. You successfully added the noatime option to your root drive (/). Verified with the format command I presume

Now you need to find the plist file that mounts your second drive.... a simple 'grep -r "Volumes/Data" *' run from within the /Library/LauchDaemons directory should do it.

Actually, they are two partitions on the same drive. My setup is as follows:

SSD in the HDD bay, with two partition (Macintosh HD and Data). I only have this one hard disk.

This works for me:

In the terminal write this:

cd /usr/local/bin
sudo nano remount_noatime

Type your password and a terminal based text editor opens.

Fill it with this:

#!/bin/bash
/sbin/mount -uwo noatime /Volumes/Data

Press Ctrl+X, then y to exit.

Type this in the terminal:

sudo chmod +x /usr/local/bin/remount_noatime
sudo defaults write com.apple.loginwindow LoginHook /usr/local/bin/remount_noatime

Delete the plist you created for noatime for the Data volume in /Library/LaunchDaemons if you still have it.

Reboot to see changes.

Thanks a lot! That worked like a charm.
