Installed ES, the logstash and Kibana bits. Ran some data into it, looked good.
Deleted the indices because: did not want the old, bad, data in there.
Deleted ES because of an issue with upgrading that may have caused the indices to go red.
Installed ES. Spent a few hours loading up good data from log.
Restarted ES. My bad data came back. The good stuff is no longer there. What happened?
I vaugley recall reading a stackoverflow entry on this, but can't find it.
Using CURL to remove indices doesn't remove it from disk?
Can I get my good data back?
How can I make the ratty stuff actually go away?
Edit. I had a moment to circle back to this. Thought about it. Did a search on disk and found this (sample)
First line is the new indices. Second line is the old data, from the first install.
I guess that I can delete the data from disk restart elasticsearch and .. things will be okay?
