1）清理ovirt相关服务（包括HA,engine）：

停用并卸载ovirt,vdsm,libvirt相关的服务。yum remove ovirt vdsm libvirt rhev glusterfs postgresqlrm -rf /etc/ovirt /etc/vdsm /etc/libvirt /etc/pki/vdsm /etc/pki/libvirt /etc/pki/CA/cacert.pem /var/run/vdsm /var/run/libvirt /var/lib/vdsm /var/lib/libvirt /var/lib/ovirt /var/lib/pgsql /var/log/ovirt /var/log/vdsm /var/log/libvirt

如果需要清理vdsm管理的multipath：

首先，查看列表：multipath -l清空：multipath -F移除包：yum remove multipath2)安装：yum install ovirt-engine ovirt-engine-dwh恢复数据库：engine-backup --mode=restore --log=restore1.log --file=备份数据路径 --provision-db --provision-dwh-db --no-restore-permissions配置：engine-setup
