Storage Engine did not migrate to WiredTiger after upgrade to Splunk 9.0.2?

SplunkNinja — Tue, 29 Nov 2022 15:28:19 GMT

Hello everybody!

My standalone SH Storage Engine did not migrate to WiredTiger after upgrade to Splunk 9.0.2. I then followed these steps: https://docs.splunk.com/Documentation/Splunk/8.1.3/Admin/MigrateKVstore

Migrate the KV store after an upgrade to Splunk Enterprise 8.1.* or 8.2.* in a single-instance deployment

Stop Splunk Enterprise. Do not use the -f option.
Open server.conf in the $SPLUNK_HOME/etc/system/local/ directory.
Edit the storageEngineMigration setting to match the following example:

[kvstore]
storageEngineMigration=true

Save the server.conf file.
To begin the migration, use the following command:

splunk migrate kvstore-storage-engine --target-engine wiredTiger

Starting KV Store storage engine upgrade:
Phase 1 (dump) of 2:
..ERROR: Failed to migrate to storage engine wiredTiger, reason=

How can I troubleshoot this further? Thanks.

Try again using the documentation for the version you are running. https://docs.splunk.com/Documentation/Splunk/9.0.2/Admin/MigrateKVstore

Hello Rich,

I followed the 9.0.2 steps with the same results. My mongodb.log is showing issues with SSL. Not sure why we see - connecting with a certificate with cluster membership

This is supposed to be a standalone SH. Not sure what to try next. Thanks.

TBH, I'm more concerned about the "connection rejected" errors than the "connecting with a certificate" warning, but either way I don't have a solution for you. I suggest double-checking all of your KVstore settings. Contact Splunk Support if you have an entitlement.

Thanks Rich.

I have opened a Support case to further investigate.
