After I successfully installed the Splunk Enterprise on my Oracle Vbox, I got a message that says: "The minimum free disk space (5000MB) reached for /opt/splunk/var/run/splunk/dispatch". Then I used the (sudo du -sh /opt) command and I found that the /opt directory resides the space 3.8G (less than 5.0G), even though, I allocated 40G for the machine at all !! My question is how to increase the disk space given for the /opt directory? PS: The health status of IoWalt under the resource usage is RED!!
