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.
