Why is Splunk Service not starting with 'authDb' error?

[NicholasLeader]

Hi - any idea why my Splunk service is failing with this error?

What is 'authDb'?

~]# service splunk start
Starting Splunk...

Splunk> CSI: Logfiles.

It would seem Splunk does not have permissions to write. Confirm the user Splunk runs as has ownership of the installation and that there are no storage issues.

chown -R splunk:splunk /mnt/*
