Where is the first part of the index home path defined?

[summitsplunk]

I've sort of took on Splunk administration for my company so I'm trying to make sense of this as quickly as I can.

Under Indexes I see you can define a "Home Path" and here is what I currently see:

When I place my mouse over the row it displays "/opt/splunkdata/smt_tableau/db" but notice how the Home Path is titled as "volume:summit_ps/smt_tableau/db" in the picture.

So I'm guessing there's a place where "volume:summit_ps" is defined to look in /opt/splunkdata but I can't find it anywhere.

Sorry if this is confusing.

Actually I just

grep -r volume:summit_ps *

This command will show you where it is defined:

./bin/splunk btool indexes list volume:summit_ps --debug
