I am re-architecting our Splunk environment. I have mounted various volumes to each of my indexers (3 total) for hot, warm and cold buckets.
To do this I have set volumes in an indexes.conf file I will deploy via Deployment Server to the 3 indexers.
[volume:hot_warm] path = /splunk_data/hot_warm #DISK SIZE = 2.9TB maxVolumeDataSizeMB = 2800000 [volume:cold] #DISK SIZE = 8.8TB path = /splunk_data/cold maxVolumeDataSizeMB = 8700000
My question is, will this config set volumes globally for all indexes on the indexer? That is, if another app has an index=x, will that index write hot data to the path; "/splunkdata/hotwarm", for example?
As long as when you set up homePath=volume:hot_warm/indexname/db/ in each indexes.conf for each index, then yes. homePath is a required value, so that should be easy.
All you've done so far is tell Splunk that there ARE volumes...you haven't yet told an index to use them.
Is there anyway to set the path to the volumes globally for each indexer, so that each index uses these volumes by default for the appropriate bucket?
I corrected my original answer, but you already HAVE told Splunk that the volumes exist, but the homePath value is required PER index...so not really a way to set that globally. You should have indexes.conf that get deployed with the apps as well where you could update the homePath.
