ceph osd set-require-min-compat-client jewel failure - ceph-users

2 Sep 2019

hi,every one,
my ceph version 12.2.12，I want to set require min compat client
luminous,I use command
#ceph osd set-require-min-compat-client luminous
but ceph report:Error EPERM: cannot set require_min_compat_client to
luminous: 4 connected client(s) look like jewel (missing
0xa00000000200000); add --yes-i-really-mean-it to do it anyway
[root@node-1 ~]# ceph features
{
    "mon": {
        "group": {
            "features": "0x3ffddff8eeacfffb",
            "release": "luminous",
            "num": 3
        }
    },
    "osd": {
        "group": {
            "features": "0x3ffddff8eeacfffb",
            "release": "luminous",
            "num": 15
        }
    },
    "client": {
        "group": {
            "features": "0x40106b84a842a52",
            "release": "jewel",
            "num": 4
        },
        "group": {
            "features": "0x3ffddff8eeacfffb",
            "release": "luminous",
            "num": 168
        }
    }
}

so,I run command:
[root@node-1 gyt]# ceph osd set-require-min-compat-client luminous
--yes-i-really-mean-it
set require_min_compat_client to luminous

but now,I want to set require min compat client jewel,I use command：

[root@node-1 gyt]# ceph osd set-require-min-compat-client jewel
Error EPERM: osdmap current utilizes features that require luminous;
cannot set require_min_compat_client below that to jewel

what‘s the way we are set luminous chang to jewel？
