これは3つのノードの私の設定ですが、最近追加したnetfisでのみ失敗します。

totem {
    version: 2
    secauth: off
    cluster_name: cluster-osiris
    transport: udpu
}

nodelist {
    node {
        ring0_addr: isis.localdoamin
        nodeid: 1
    }

    node {
        ring0_addr: horus.localdoamin
        nodeid: 2
    }

    node {
        ring0_addr: netfis.localdoamin
        nodeid: 3
    }
}

quorum {
    provider: corosync_votequorum
}

logging {
    to_syslog: yes
}

私はCentOS 7.1 64ビットでPacemaker、corosync、PCクラスタを実行しています。

インターネットで検索しましたが、何が起こっているのかわかりません。

助けてください？
