Setting up a caching pool in your Ceph cluster.

Adding caching tier to your filesystem

First we need to check our pools and create a new cache pool.

sudo ceph osd lspools
sudo ceph osd pool create hot_storage 32

Next up we setup the pool as a tier for your data drive and change the mode to writeback which means that you first write to it before flushing it back to your slower drives. readproxy is better if you have the same kind of speed on your pools as it writes to the data drive and then adds entries to your cache pool when read often.

This gist was essentially created out of my own rant about Netflix being hostile to IPv6 tunnel services since June 2016. You are welcome to read my opinion on the matter, this is the more technical side to the issue and how to combat it within your own network.

Since I wrote this, various GitHub users have contributed their thoughts and ideas which has been incorporated into this gist. Thank you to everyone who have contributed their own methods and implementations.

The problem

Netflix now treats IPv6 tunnel brokers (such as Hurricane Electric) as proxy servers. A while ago it became apparent to users and Netflix that somewhat by accident, IPv6 tunnel users were being served content outside of their geolocation because of the way Netflix was identifyi
