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.
