Remove Raw data from splunk server

[npandith]

We are running splunk 4.2.3 on a RHEL 5.7 server and nearly 250 universal forwarders forwarding data to this splunk server. Right now we have 2 mounts created, 1 for hot/warm db's and 1 for colddbs. We are indexing appr. 80G of data everyday and space is filling up very fast and we have appr.1TB of data. Out of this raw data is consuming more space. I am planning to remove rawdata from the colddb. IS IT OK TO REMOVE THE RAWDATA FROM COLDDB? i guess splunk will not touch rawdata's.

output from one of the cold db-

ls -ltr

Hum, not the best idea, removing raw data means that you will not be able to access the data after, therefore those cold buckets will be useless.

if you really want to delete cold buckets, then setup a retention policy (on total index size or on time retention.)
