Determine which indexes.conf changes require restart

Some changes to indexes.conf require that you restart the indexer for the changes to take effect:

  • Changing any of these attributes: rawChunkSizeBytes, minRawFileSyncSecs, syncMeta, maxConcurrentOptimizes, coldToFrozenDir, coldtoFrozenScript, memPoolMB
  • Changing any of these attributes for existing indexes: repFactor, homePath, coldPath, thawedPath, bloomHomePath, summaryHomePath, tstatsHomePath, remotePath, coldPath.maxDataSizeMB, datatype
  • Adding or removing a volume
  • Enabling or disabling an index that contains data
  • Removing an index

You do not need to restart the indexer if you only make these changes:

  • Adding new index stanzas.
  • Changing any attributes not listed as requiring restart
  • Enabling or disabling an index that contains no data

The configuration changes that cause the peer nodes in an indexer cluster to undergo a rolling restart are a superset of those listed here. See Restart or reload after configuration bundle changes?

Note: For information on other configuration changes, outside of indexes.conf, that require a restart, see When to restart Splunk Enterprise after a configuration file change in the Admin Manual.
