Ceph client still using luminous while on Squid

[qontinuum]

Hello,

I am trying to put the balancer mode into upmap-read which requires to run: ceph osd set-require-min-compat-client reef
I can't do so because I have a single client running on luminous compat version:

# ceph features
{
    "mon": [
        {
            "features": "0x3f03cffffffdffff",
            "release": "squid",
            "num": 1
        }
    ],
    "osd": [
        {
            "features": "0x3f03cffffffdffff",
            "release": "squid",
            "num": 8
        }
    ],
    "client": [
        {
            "features": "0x2f018fb87aa4aafe",
            "release": "luminous",
            "num": 1
        },
        {
            "features": "0x3f03cffffffdffff",
            "release": "squid",
            "num": 20
        }
    ],
    "mgr": [
        {
            "features": "0x3f03cffffffdffff",
            "release": "squid",
            "num": 1
        }
    ]
}

I find nothing about it in the documentation or forum and don't find a way to get what is this client. Is there a solution for this (like finding the concerned client)?

ceph daemon mon.[id] sessions | grep -A20 -B20 -i luminous

It gives me this entry:

    {
        "name": "unknown.0",
        "entity_name": "client.admin",
        "addrs": {
            "addrvec": [
                {
                    "type": "none",
                    "addr": "[REDACTED]:0",
                    "nonce": [REDACTED]
                }
            ]
        },
        "socket_addr": {
            "type": "none",
            "addr": "[REDACTED]:0",
            "nonce": [REDACTED]
        },
        "con_type": "client",
        "con_features": 3387146417253690110,
        "con_features_hex": "2f018fb87aa4aafe",
        "con_features_release": "luminous",
        "open": true,
        "caps": {
            "text": "allow *"
        },
        "authenticated": true,
        "global_id": [REDACTED],
        "global_id_status": "reclaim_ok",
        "osd_epoch": [REDACTED],
        "remote_host": ""
    }

It seems it is the only entry with an entity_name that is client.admin but with a name that is unknown.0, the other ones have client.?.
