One of my indexers is about to reach its storage capacity. I am trying to figure out if/when that happens, will A) all indexers stop indexing or B) will clustering and indexing continue as normal and avoid using indexer 3?
The indexer will enter 'detention' state (by default, when there is 5gb left), where it will no longer get any replications / indexing. See http://docs.splunk.com/Documentation/Splunk/6.2.4/Indexer/Howtomonitoracluster#Peers_tab (detention status) and http://docs.splunk.com/Documentation/Splunk/6.2.4/Indexer/Setlimitsondiskusage (minFreeSpace dictates when we go into 'detention')
