Dear Team,

Our /tmp directory is being often filled with temporary files from users running jobs on the machine. As a result, we'd like to move the /tmp directory to a secondary partition so that:

1) / does not get filled up so often when users can't specify TMPDIR in their applications.
2) The secondary partition is a 1TB SSD which will take time to get filled up and because it's SSD, will add up some speed.

I believe an entry should be added to fstab for this device, specifiying the UUID and mountpoint. But as this is a production machine, I would really appreciate some feedback, if anyone has successfully done this change in the past.


I understand that the lifetime of the SSD will be greatly reduced, but this is offset by the gains we shall be having afterwards. I searched on the ubuntu forums but I could only find a procedure for moving /home folders.

So, you have second ssd with partition and filesystem created.
You can check under /dev/disk/by-uuid/ for UUID of the disk.
Then update fstab...

Since you have user jobs writing to /tmp, I would make sure no jobs are running then rename existing /tmp to something else then mount the new partition as /tmp

thanks a lot!

Not to detract from having a /tmp directory, but how about having an automated script that deletes the temporary files?

Moved: This thread is more suitable in <Ubuntu> and has been moved accordingly to help your thread/question get the exposure it deserves.

You can hardly be sure if /tmp is not in use.
I would rather set it in fstab and reboot. Also need to clean up the original /tmp.
