I am unaware of any way to accomplish having 1 pool with all 3 racks and
another pool with only 2 of them. If you could put the same osd in 2
different roots or have a crush rule choose from 2 different roots, then
this might work out. To my knowledge neither of these is possible.
What is your rea
Hello,
I'm building a 5 server cluster over three rooms/racks. Each server has 8
960GB SSDs used as bluestore OSDs. Ceph version 12.1.2 is used.
rack1: server1(mon) server2
rack2: server3(mon) server4
rack3: server5(mon)
The crushmap was built this way:
ceph osd
