Hello,
With ceph-ansible the default replicated crush rule is :
{
"rule_id": 0,
"rule_name": "replicated_rule",
"ruleset": 0,
"type": 1,
"min_size": 1,
"max_size": 10,
"steps": [
{
"op": "take",
"item": -1,
"item_name": "default"
},
{
"op": "chooseleaf_firstn",
"num": 0,
"type": "host"
},
{
"op": "emit"
}
]
}
And I would like to have this:
{
"rule_id": 0,
"rule_name": "replicated_rule",
"ruleset": 0,
"type": 1,
"min_size": 2,
"max_size": 4,
"steps": [
{
"op": "take",
"item": -1,
"item_name": "default"
},
{
"op": "chooseleaf_firstn",
"num": 0,
"type": "rack"
},
{
"op": "emit"
}
]
}
How can I do this within ceph-ansible playbook ?
I try :
crush_rule_replicated:
name: replicated_rule
root: default
ruleset: 0
type: replicated
min_size: 2
max_size: 4
step:
- take default
- chooseleaf firstn 0 type rack
- emit
default: true
crush_rules:
- "{{ crush_rule_replicated }}"
task path: roles/ceph-osd/tasks/crush_rules.yml:32 try to change it but it fail:
stdout_lines:
- ''
-
'{"rule_id":0,"rule_name":"replicated_rule","ruleset":0,"type":1,"min_size":1,"max_size":10,"steps":[{"op":"take","item":-1,"item_name":"default"},{"op":"chooseleaf_firstn","num":0,"type":"host"},{"op":"emit"}]}'
Anyone have an idea ?
Regards
Marc
