How to resolve minimum disk space usage limit issue for splunk-optimize?

[hyahmadi]

Hello,
I executed the search command first in Splunk Web, then in a free instance Splunk connected to the search peer, but the problem is the second one didn't return a result? I also received the following message "splunk-optimize may be prevented from running if the minimum disk space usage limit is reached." What I should do to resolve this incident?
thanks

If you can not remove disk space ? you can modify the "Pause indexing if free disk space (in MB) falls below this value" in
http://MYSPLUNKSERVER:8000/en-US/manager/search/server/settings/settings?action=edit and may have to restart Splunk.
