Longhorn安装

# 磁盘准备

为每个 K8s 节点虚拟机创建 ZFS 卷

zfs create -V 100G /data/k8s-node1-disk
zfs create -V 100G /data/k8s-node2-disk

将 ZFS 卷附加到虚拟机

qm set 101 -scsi1 /dev/zvol/data/k8s-node1-disk
qm set 102 -scsi1 /dev/zvol/data/k8s-node2-disk

在 K8s 节点中格式化并挂载

mkfs.ext4 /dev/sdb
mkdir /data/longhorn
echo "/dev/sdb /data/longhorn ext4 defaults 0 0" >> /etc/fstab
systemctl daemon-reload
mount -a

kubectl label nodes k8s-master-01 node.longhorn.io/create-default-disk=true
kubectl label nodes k8s-master-02 node.longhorn.io/create-default-disk=true
kubectl label nodes k8s-node-01 node.longhorn.io/create-default-disk=true
kubectl label nodes k8s-node-02 node.longhorn.io/create-default-disk=true
