As far as I can tell (not *exactly* an expert here), my failre domain is set to host, with a simple 
erasure code profile:


root@s1:~# ceph osd erasure-code-profile ls
default
root@s1:~# ceph osd erasure-code-profile get default
k=2
m=1
plugin=jerasure
technique=reed_sol_van

root@s1:~# ceph osd crush rule dump
[
    {
        "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"
            }
        ]
    },
    {
        "rule_id": 1,
        "rule_name": "erasure-code",
        "ruleset": 1,
        "type": 3,
        "min_size": 3,
        "max_size": 3,
        "steps": [
            {
                "op": "set_chooseleaf_tries",
                "num": 5
            },
            {
                "op": "set_choose_tries",
                "num": 100
            },
            {
                "op": "take",
                "item": -1,
                "item_name": "default"
            },
            {
                "op": "chooseleaf_indep",
                "num": 0,
                "type": "host"
            },
            {
                "op": "emit"
            }
        ]
    }
]


The pool was using the erasure code crush map, not the replicated one.
