====== Crypto - Chia - CLI - Plot - Plot with a ramdisk ======

Using a Ramdisk can speed up plotting.

<WRAP info>
**NOTE:**  This requires at least 256GB of RAM available.

===== Create a Ramdisk =====

<code bash>
mkdir /mnt/ramdisk
mount -t tmpfs -o rw,size=240G tmpfs /mnt/ramdisk
</code>

<WRAP info>
**NOTE:**  This mounts a ramdisk with 240GB under the path /mnt/ramdisk.

  * **-t tmpfs**:  
    * tmpfs only uses memory when you it contains files.
    * When it is empty, it will take almost no space in RAM.

See: https://manpages.debian.org/buster/initscripts/tmpfs.5.en.html

===== Verify the Ramdisk =====

Verify that the RAMDISK has been created.

<code bash>
df -h
</code>

----

===== Mount the Ramdisk automatically on system boot =====

Edit /etc/fstab, and add the following line to the the end of the file.

<file bash /etc/fstab>
tmpfs  /mnt/ramdisk  tmpfs  rw,size=240G  0   0
</file>

===== Create the Chia Plot =====

Creates a new plot.

<code bash>
chia plots create -k 32 -r 6 -n 1 -t /mnt/ramdisk -2 /home/peter-chia-temp -d /home/peter-chia
</code>

<WRAP info>
**NOTE:**  

  * **-k32**:  Creates a k32 plot.
  * **-r 6**:  Specifies six processor cores.
    * These cores are used primarily in phase 1 and 2.
  * **-n 1**:  Creates exactly one plot.
  * **-t /mnt/ramdisk**:  Specifies the temporary directory.
  * **-2 /home/peter-chia-temp**:  Specifies the second temporary directory (Optional).
    * Depending on the size of the ramdisk, this optionn might be needed otherwise there could be insufficient memory to write the plot file at the end.
  * **-d /home/peter/chia**:  Specifies the final directory for the plot.
