# 安装 HwameiStor 

helm repo add daocloud https://release.daocloud.io/chartrepo/daocloud
helm repo update
helm upgrade hwameistor daocloud/hwameistor  --install -n hwameistor --create-namespace --set k8sImageRegistry=quay.m.daocloud.io --set hwameistorImageRegistry=ghcr.m.daocloud.io

# 安装 SC https://github.com/hwameistor/local-storage/blob/main/deploy/storageclass-lvm-ha.yaml

cd /tmp

cd /tmp/local-storage/deploy

kubectl apply -f storageclass-lvm.yaml
kubectl apply -f storageclass-lvm-ha.yaml


# 添加磁盘（盘要大一些 ，不小于 100GB ）

kubectl label node node2 "lvm.hwameistor.io/enable=true"
kubectl label node node4 "lvm.hwameistor.io/enable=true"

# 修改 hwameistor-scheduler 无法启动，可以修改一下 

node-role.kubernetes.io/master => node-role.kubernetes.io/control-plane


# 无 DRBD 模式的 Wordpress 安装

kubectl patch storageclass local-storage-hdd-lvm -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'

kubectl get sc

helm repo add community https://release.daocloud.io/chartrepo/community
helm repo update

helm install wp -n wp1 community/wordpress --set global.imageRegistry=docker.m.daocloud.io --set image.debug=true --set schedulerName=hwameistor-scheduler --set mariadb.schedulerName=hwameistor-scheduler --create-namespace

# 安装 DRBD
# 要求使用 DRBD 9 版本以上
# 要求 hostname 和 nodename 相同

sudo apt-add-repository ppa:linbit/linbit-drbd9-stack
sudo apt-get update
sudo apt-get install -y drbd-dkms
sudo modprobe drbd
modinfo drbd


kubectl patch storageclass local-storage-hdd-lvm -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"false"}}}'
kubectl patch storageclass local-storage-hdd-lvm-ha -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
kubectl get sc

helm install wp -n wp2 community/wordpress --set global.imageRegistry=docker.m.daocloud.io --set image.debug=true --set schedulerName=hwameistor-scheduler --set mariadb.schedulerName=hwameistor-scheduler --create-namespace

# 选择一个节点驱逐，测试高可用

kubectl drain node4  --ignore-daemonsets
kubectl get lv

成功完成了 节点的容灾。 牛B
