Simone;
What is your failure domain?
If you don't know your failure domain can you provide the CRUSH ruleset for
the pool that experienced the "object unfound" error?
Thank you,
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.
