Hello,
we are currently running our Elasticsearch on 1 single node and get about
20 Million Logs per Day(40 GB/daily indices). Since this is a much Stuff to
handle with, the indices takes a lot of disk space on our server.
What we like to implement:
- 1 Data directory which is stored on our SSDs and contains the indices of
the last 7 days for quick access.
- 1 Data directory which is stored on normal HDDs and contains indices of
last 3 months for normals speed acces.
- 1 Data directory which is stored on slow 5400 rpm HDDs and contains the
indices of the last 2 years for access if needed.
Well it´s not problem to tell ES multiple data paths but if you do this, ES
will stripe (RAID 0) the indices on all 3 data directories.
But thats not what we want. We want do copy the indices with a script to
the matching directories ( a index which is older than 8 days gets
automatically moved to normal HDDs and so on).
Is there any way to make this work?
Thanks for your feedback.

Assuming these are all in the same server; You can't do this unless you run
multiple instances and then tell each instance which directory (mount) to
store the data.
You'd then need to use something like this
