I have the following message:
The minimum free disk space (2000MB) reached for /app/list/splunk/var/run/splunk/dispatch.
However, I have checked and there is no data on this directory. Do you know, when you are searching data on the indexers, if the result of the search is stored on the master dispatch directory or the indexers dispatch directories?
Note that Splunk is complaining about the minimum free space available to the directory, so make sure the volume that the directory is on has more than 2000MB of free space (
df -h for a quick check)
As @Jmichaelis said, see https://answers.splunk.com/answers/214804/the-minimum-free-disk-space-5000mb-reached-for-opt.html for more details
The files of a search will be deleted when the lifetime of it expires (after a few minutes).
Your folder has a minimum free space configuration which has expired for this particular folder. The same propably applies to the whole splunk directory. You can reduce the minimum free space for the splunk folder in server.conf
[diskUsage] minFreeSpace = <num>
The question has been asked at: https://answers.splunk.com/answers/214804/the-minimum-free-disk-space-5000mb-reached-for-opt.html and was answered allready.
Searches results are stored in $SPLUNK_HOME/var/run/splunk/dispatch.
Searches have a lifetime and probably when you see in the directory they were expired.
Otherwise, did you checked the maximum space availability for your role? I had a similar problem and the solution was to enlarge the space for searches for the role admin.
you can do it in settings - roles.
I downvoted this post because the min free space error has nothing to do with the max search disk size.
