Hi,
Not sure when this occurred exactly however all of the indexes with an _ prefix are currently disabled on my indexer (non clustered distributed environment, 1 indexer + 1sh). I did reduce the size of the _internal index a while back which may be related, I have since changed this back and restarted to no avail.
splunkd.log does not show any related warnings or errors on restart as far as i can see. see below for end of splunkd.log after restart.
The indexes.conf does not specify any disabled params on any of the indexes, how can i re-enable these indexes?
