就搭建nfs-2搞

rocky8.5系统

systemctl disable firewalld
systemctl stop firewalld

sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
setenforce 0

# 打开 https://www.elrepo.org 看具体的操作
rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
dnf install -y https://www.elrepo.org/elrepo-release-8.el8.elrepo.noarch.rpm
dnf search drbd
dnf install -y vim drbd90-utils kmod-drbd90 lvm2

drdb的方案不符合我想要的，就先暂时不记录了
