There are number of reasons exists which leads to Splunk throwing up errors with KVstore. We recently got splunk kv store errors popped up as shown below. The solving process made us realized that KVstore error can be due to anonymous issues and same error message for different reason will get pop up make it confusing for us. So to get rid of it other than pre-existing solution on internet one need to check every aspects related to KVstore directory thoroughly.

Procedure 1st: See the below steps to solve SSL related issue.
Step 1:  Go to bin directory of Splunk Search Head

  • cd $SPLUNK_HOME/bin

Step 4: Now create a new SSL certificate in the directory called $SPLUNK_HOME$/etc/auth.
Run the below command to create an SSL certificate for this server by putting FQDN value you copied through previous step. This will generate “ pem”  file in response

  • ./splunk createssl server -cert 3072 -d /opt/splunk/etc/auth -n server -c

Step 5: Now restart Splunk by bin directory and again run command to check KVstore status as listed above it will be showing ready if it was related to SSL certificate issue

Procedure 2nd Steps to solve mongodb related issue.

Step 1: Open the CLI of this Search Head. Go to Kvstore directory

  • cd $SPLKUNK_HOME/var/lib/splunk/kvstore

Step 2:  Run below command to change ownership if it is misplaced by any chance in KVstore or any other directory in it.

In our case some mongodb directory files inside /kvstore/mongodb were in root ownership.
It got changed to Splunk, and all error message resolved 😊

  • chown -R splunk:splunk /opt/splunk/var/lib/kvstore/mongodb
