Can the data files under the ../smartstore/coll/archive directory be removed manually or do they need to be cleaned up via the SmartStorTools.sh script? We are running into some disk space issues and need to cleanup old files to re-gain space on the filesystems.
Safest and recommended way to clean smartstor is to prune using smtartstor tool. by doing prune only metrics without data will be remove and your metrics with data will be safe. For pruning you have to stop EM and run prune command and start again.
If you don't care about the metrics with data and have lots of old ***.data files in your /data/archive folder you can delete some old dated files and restart your EMs.
