How to change the index size of _audit index on a cluster?

[agentguerry]

I have a cluster set up with 1 index master, and 2 index peers.

I would like to change the size of the _audit index from 500G to 400G.

How can I go about changing these? On my index master, in the inputs.conf file that gets pushed out, there is no _audit index since these are created from splunk setup. I cannot go to each peer and change them manually, b/c the peers are part of a cluster.

Thanks!

On both indexers, you would need to create a stanza.
go to $SPLUNK_HOME/etc/system/local/indexes.conf

and create

[_audit]

[agentguerry]

would doing that clobber the existing data/index that is on the peer servers?
