Error running mongod command in Tokumx

Question

I am trying to install Tokumx mongodb inside ubuntu VM using Putty. I have followed all the steps to install tokuMX mongodb from the link http://docs.tokutek.com/tokumx/tokumx-installation.html I have created /data/db folder inside root and given permission. when I ran mongod command , I got an error -> this is the screenshot.

It creates mongod.lock file inside data folder , I tried deleting that file and ran but got the same error. How to fix it? Any idea?

Answer 1

As said in the error message, you have to disable the transparent huge pages before launching mongod.

echo never > /sys/kernel/mm/transparent_hugepage/enabled

On Red Hat:

echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled
