Re: [ceph-users] krbd / kcephfs - jewel client features question

Hello llya,

After updated client kernel version to 3.10.0-862 , ceph features shows:

"client": {
        "group": {
            "features": "0x7010fb86aa42ada",
            "release": "jewel",
            "num": 5
        },
        "group": {
            "features": "0x7fddff8ee8cbffb",
            "release": "jewel",
            "num": 1
        },
        "group": {
            "features": "0x3ffddff8eea4fffb",
            "release": "luminous",
            "num": 6
        },
        "group": {
            "features": "0x3ffddff8eeacfffb",
            "release": "luminous",
            "num": 1
        }
    }

both 0x7fddff8ee8cbffb and 0x7010fb86aa42ada are reported by new kernel
client.

Is it now possible to force set-require-min-compat-client to be luminous,
if not how to fix it?

Thanks
