No. (until you don't wrongly modify the crushmap manually)

with replicat x2, if you loose 2osd on 2differents nodes, with the same object
inside, you'll lost the object

Objet: [ceph-users] Multiple OSD's in a Each node with replica 2
I have a doubt . In a scenario (3nodes x 4osd each x 2replica) I tested with a
node down and as long as you have space available all objects were there.
Is it possible all replicas of an object to be saved in the same node?
Is it possible to lose any?
Is there a mechanism that prevents replicas to be stored in another osd in the
same node?
I would love someone to answer it and any information is highly appreciated.
