I tried it but it didn't work:

Did you change your plex settings to use that path? It does look like your tmpfs mounted correctly under /ramdisk. Remember you need to change your Plex Settings to actually use it. Attached you can find how I setup up mine and then inside the Plex setup you set it to use the /transcode path.

This is really odd, I have been using this for a long time, did you try running the commands manually? Any errors?

Like:
mkdir /ramdisk
mount -t tmpfs -o size=2048m tmpfs /ramdisk

 

This is my go file and the output of df -h which shows the /ramdisk of 2GB:

# cat /boot/config/go
#!/bin/bash
# Start the Management Utility
#ethtool -K eth0 tx off sg off tso off
/usr/local/sbin/emhttp &
mkdir /ramdisk
mount -t tmpfs -o size=2048m tmpfs /ramdisk

# df -h

Hi Guys,

 

Yes, trurl, sorry for the typo that is correct, I have also tested adding lines to the /boot/go script and it works great.

Here are the reviewed steps , including the go script change:
 

1) Login using SSH to your Unraid server > ssh root@unraid(IP)

2) mkdir /ramdisk

3) mount -t tmpfs -o size=1024m tmpfs /ramdisk

4) This will create a 1G /ramdisk

5) Set Plex set to container (/transcode) host (/ramdisk)

6) Change Plex settings to /transcode

7) Be happy .. you can actually go inside the folder too: cd /ramdisk, start a movie and do a couple of ls or df -h and you will see that being used.
8) To make it persistent, you can add the lines to the go script under /boot/config
9) Here are the lines in mine that are working:
#!/bin/bash
# Start the Management Utility
/usr/local/sbin/emhttp &
ethtool -K eth0 tx off sg off tso off
mkdir /ramdisk
mount -t tmpfs -o size=1024m tmpfs /ramdisk

NOTE: This is my whole go script, the only lines you really need are the last two ones to be added to whatever you have setup.

Hi Guys,

 

I think the easiest way to do this and to make sure it works is:

 

1) Login using SSH to your Unraid server > ssh root@unraid(IP)

2) mkdir /ramdisk

3) mount -t tmpfs -o size=1024m tmpfs /mnt/ramdisk

4) This will create a 1G /ramdisk

5) Set Plex set to container (/transcode) host (/ramdisk)

6) Change Plex settings to /transcode

7) Be happy .. you can actually go inside the folder too: cd /ramdisk, start a movie and do a couple of ls or df -h and you will see that being used.

 

Enjoy!
