I'm going to make a new ceph test cluster and have some tuning questions.
We'll be using a 4 disk raid-10 on each node + a hot spare . There will be one OSD per node. We do not need super fast I/O , instead our priority is high availability + always great keyboard response. We'll use this ssd for journal: Intel DC S3700 Series 200GB .
Does anyone know how we could set these:
* replica of 2
* permanently set OSD noout ?
*the "mon osd downout subtree limit" set to "host"
thank you and best regards
