Hi all, I am quite new with Ceph Storage. Currently we have a Ceph environment running, but in a few months we will be setting up a new Ceph storage environment. I have read a lot of information on the Ceph website, but the more information the better for me. What book(s) would you suggest? I found the following books: Learning Ceph – Karan Singh (Jan 2015) Ceph Cookbook – Karan Singh (Feb 2016) Mastering Ceph – Nick Fisk (May 2017) Another question; Ceph is self-healing, it will distribute the replicas to the available OSD’s in case of a failure of one of the OSD’s. Lets say my setup is configured to have 3 replicas, this means when there is a failure of one the OSD’s it will start healing. I want that when an OSD fails and only 2 replicas are left, it shouldn’t do anything, only when also the 2nd OSD fails it should start replicating/healing. Which configuration setting do I need to use, is it the min size option? Thanks! |
