Hi,
I have 2 hosts with 8 2TB drive in each.
I want to have 2 replicas between both hosts and then 2 replicas between osds
on each host. That way even when I lost one host I still have 2 replicas.
Currently I have this ruleset:
rule repl {
ruleset 5
type replicated
min_size 1
max_size 10
step take asterix
step choose firstn -2 type osd
step emit
step take obelix
step choose firstn 2 type osd
step emit
}
Which works ok. I have 4 replicas as I want and PGs are distributed perfectly
but when I run ceph df I have only 1/2 of my capacity which I should have.
In total it's 32TB, 16TB in each host. If there is a 2 replicas on each host it
should report around 8TB, right? It's reporting only 4TB in pool which is 1/8
of total capacity.
Can anyone tell me what is wrong?
Thanks
