标签：systemd 调用 vendor Owner spl removing temp setup pmi
环境ironic-api ironic-conductor,ironicclient均升级为Queens版本
官网说明API版本为1.38才支持rescue/unrescue，所以修改下openrc文件
export OS_PROJECT_DOMAIN_NAME=default export OS_USER_DOMAIN_NAME=default export OS_PROJECT_NAME=admin export OS_USERNAME=admin export OS_PASSWORD=ADMIN_PASS export OS_AUTH_URL=http://172.18.211.69:10006/v3 export OS_IDENTITY_API_VERSION=3 export OS_IMAGE_API_VERSION=2 export IRONIC_API_VERSION=1.38
同时应该当前用的裸机镜像更新属性，加上ramdisk_id和kernel_id

需要修改下ironic配置文件，增加resuce接口和rescuing_network

更新node的driver_info和driver
ironic node-update b2e71756-750c-47b9-b08a-9ae577d1098a add driver_info/rescue_kernel=0c0d1bf2-cf15-4754-b885-3df251c1206c driver_info/rescue_ramdisk=5bcf0917-429-42eb-b93b-3cdb50a8008e ironic node-update b2e71756-750c-47b9-b08a-9ae577d1098a replace driver=ipmi
官网releasenotes说明Queens ipa版本支持rescue和unrescue，但是ironicclient 无法调取rescue command,且文档没更新
[root@172e18e211e25 ~]# ironic node-set-provision-state bm172e18e211e24 unrescue
The "ironic" CLI is deprecated and will be removed in the S* release. Please use the "openstack baremetal" CLI instead.

说明已进入到救援模式，此刻登陆下IMPI console看下裸机状态
正在加载救援镜像
加载完成，进入到deploy ramdisk
ironic节点ssh登入系统，lsblk可查看到原系统磁盘，挂载后可chroot进入系统，进行一些修复操作等

且按照ipa代码rescue.py来看，ipa会将传入的rescue_password加密写入到/etc/ipa-rescue-config/ipa-rescue-password文件，并关闭API接口
host-192-168-1-110 ~ # cat /etc/ipa-rescue-config/ipa-rescue-password EtaadfdlDFO7k
同时ipa会运行finalize_rescue.sh脚本，路径在/usr/share/oem/下
#!/bin/bash
create_rescue_user() {
echo "Adding rescue user with root privileges..."
crypted_pass=$(</etc/ipa-rescue-config/ipa-rescue-password)
sudo useradd -m rescue -G sudo -p $crypted_pass
sudo echo "rescue ALL=(ALL) NOPASSWD: ALL" > /etc/sudoers.d/rescue
}
setup_dhcp_network() {
DHCP_CONFIG_TEMPLATE=/usr/share/oem/rescue-dhcp-config.network
echo "Configuring DHCP networks on all interfaces..."
echo "Removing all existing network configuration..."
sudo rm /etc/systemd/network/*
echo "Configuring all interfaces except loopback to DHCP..."
for interface in $(ls /sys/class/net) ; do
if [ $interface != "lo" ]; then
sudo sed "s/RESCUE_NETWORK_INTERFACE/$interface/" $DHCP_CONFIG_TEMPLATE > /etc/systemd/network/50-$interface.network || true
fi
done
sudo systemctl restart systemd-networkd
}
echo "Attempting to start rescue mode configuration..."
if [ -f /etc/ipa-rescue-config/ipa-rescue-password ]; then
# NOTE(mariojv) An exit code of 0 is always forced here to avoid making IPA
# restart after something fails. IPA should not restart when this script
# executes to avoid exposing its API to a tenant network.
create_rescue_user || exit 0
setup_dhcp_network || exit 0
# TODO(mariojv) Add support for configdrive and static networks
else
echo "One or more of the files needed for rescue mode does not exist, not rescuing."
fi
假设修复完文件系统后，需要恢复裸机状态，可以使用unrescue命令,此刻不需要rescue_password
