无法初始化corosync配置API错误12

Question

无法初始化在docker容器内运行的corosync。corosync-cfgtool -s命令会产生以下结果：

Could not initialize corosync configuration API error 12

/etc/corosync/corosync.conf文件具有以下内容：

compatibility: whitetank

totem {
    version: 2
    secauth: off
    threads: 0
    interface {
        ringnumber: 0
        bindnetaddr: 127.0.0.1
        mcastaddr: 239.255.1.1
        mcastport: 5405
        ttl: 1
    }
}

logging {
    fileline: off
    to_stderr: no
    to_logfile: yes
    logfile: /var/log/corosync.log
    to_syslog: yes
    debug: off
    timestamp: on
    logger_subsys {
        subsys: AMF
        debug: off
    }
}

/var/log/corosync.log文件显示以下内容：

May 02 20:13:22 corosync [MAIN  ] Could not set SCHED_RR at priority 99: Operation not permitted (1)
May 02 20:13:22 corosync [MAIN  ] Could not lock memory of service to avoid page faults: Cannot allocate memory (12)

我在一个bash脚本中运行了以下代码：

service corosync start
service corosync status
corosync-cfgtool -s

显然，它运行得太快了，没有给corosync足够的时间进行初始化。将脚本更改为以下内容似乎起到了作用：

service corosync start
service corosync status
sleep 5
corosync-cfgtool -s

我现在看到来自corosync-cfgtool -s的以下输出

Printing ring status.
Local node ID 16777343
RING ID 0
    id  = 127.0.0.1
    status  = ring 0 active with no faults
