Hi,
I'm trying to pin down a method to quickly export an index from a Splunk indexer that I can copy off to another Splunk instance on a different system.
From what I have seen thus far, that would entail me performing a roll-to-warm, stop Splunk on indexer, copy the db files, and start up Splunk on the indexer once again. Wondering if there is a better method.
Thanks for any input!

Assuming your not on Windows, you can copy your data while splunkd
is running, but your results may not be fully consistent. So some kind of files system or block-level snapshotting is ideal here to get a more consistent result. (For example, using a LVM snapshot). In this case you shouldn't need to bring splunkd
down at all, or roll your buckets from hot to warm. Of course, it all depends on what kind of event loss tolerance you can handle. And if you're looking to do a one-time copy of a bucket, or use something like rsync
on a ongoing basis (see the above link.)
Stopping and restarting splunkd
is certainly going to interrupt any running searches and put a temporary delay on any indexing. And if your actually bringing down splunkd
then even your "hot" buckets will be consistent while the splunkd
is not running. Also keep in mind that forcing a bucket roll, will NOT guarantee that all of your buckets are WARM, because splunk will immediately create new hot buckets for any events that are received between the time your script forceably rolls your buckets and the time splunkd is shut down.
Again, the more details you can provide the more helpful the people here can be.

@Lowell: thank you, this was very helpful, I'm researching something similar.
Thanks for your input, Lowell. I'm still doing a lost of investigation with a test setup, so a number of items on my end are still in flux.
You gave me a solid alternative method that I will perform some testing with. Thanks for your time!
Can you provide a high-level overview of what you are trying to accomplish? Also if you can provide some reason(s) why you can't simply use splunk event forwarding which traditionally the suggested way of distributing events across splunk instances.
