oVirt 4.5.5安装问题总结-‘Add IPv4 outbound route rules’ RTNETLINK answers: File exists

问题

报错日志类似如下：

Hosted engine redeploys failed as below message:
[ INFO ] TASK [ovirt.hosted_engine_setup : Add IPv4 outbound route rules]
[ ERROR ] fatal: [localhost]: FAILED! => {changed: true, cmd: [ip, rule, add, from, 192.168.222.1/24, priority, 101, table, main], delta: 0:00:00.003285, end: 2020-02-06 13:46:46.603994, msg: non-zero return code, rc: 2, start: 2020-02-06 13:46:46.600709, stderr: RTNETLINK answers: File exists, stderr_lines: [RTNETLINK answers: File exists], stdout: , stdout_lines: []}

原因

执行安装后没有清理之间的安装部署

解决

执行清理脚本，根据提示选择‘Y’。

ovirt-hosted-engine-cleanup

说明：每次执行部署（self-hosted enginge）失败后都要自行清理工作。
