操作步驟
修改/etc/selinux/config 文件
將SELINUX=enforcing改為SELINUX=disabled
setenforce 0//關(guān)閉seinux
modprobe drbd 加載
lsmod |grep drbd 檢查
1 初始化 drbdadm create-md <resource-name>
2 drbdadm up all //啟用所有資源
3 drbdadm -- --overwrite-data-of-peer primary data //本端設(shè)為主并將數(shù)據(jù)發(fā)送到對(duì)方
4 格式化雙方的數(shù)據(jù)盤并且 tune2fs -c -1 /dev/sdb1
