I thought I did this all correctly, but i installed ceph with rbd, and thought that the defaults would be to replicate to data between the two nodes and not just the local OSDS. I have 2 nodes(3rd strictly for monitoring), 8 drives per node. with a min of 2 copies set in the pool. Im new to ceph, but it appears the crush rule is what i need to be looking at? can someone help me understand a little better how a rule would be set up to ensure there is an accessible copy of the data on each node? is there a default place i can directly edit the crush map in a text editor or is it all through the crush command?
