_______________________________________________Dear cepher,
Currently I am working on crushmap to try to make sure the at least one copy are going to different chassis.
Say chassis1 has host1,host2,host3, and chassis2 has host4,host5,host6.
With replication =2, it’s not a problem, I can use the following step in rule
step take chasses1
step chooseleaf firstn 1 type host
step emit
step take chasses2
step chooseleaf firstn 1 type host
step emit
But for replication=3, I tried
step take chasses1
step chooseleaf firstn 1 type host
step emit
step take chasses2
step chooseleaf firstn 1 type host
step emit
step take default
step chooseleaf firstn 1 type host
step emit
At the end, the 3rd osd returned in rule test is always duplicate with first 1 or first 2.
Any idea or what’s the direction to move forward?
Thanks in advance
BR,
Luke
