The Distributed Replicated Block Device (DRBD) is a software-based, shared-nothing, replicated storage solution mirroring the content of block devices (hard disks, partitions, logical volumes etc.) between servers.

DRBD mirrors data

• In real time. Replication occurs continuously, while applications modify the data on the device.
• Transparently. The applications that store their data on the mirrored device are oblivious of the fact that the data is in fact stored on several computers.
• Synchronously or asynchronously. With synchronous mirroring, a writing application is notified of write completion only after the write has been carried out on both computer systems. Asynchronous mirroring means the writing application is notified of write completion when the write has completed locally, but before the write has propagated to the peer system.

INSTALL

1.下载drbd源包，这里我们下载目前最新版本8.3.6

http://oss.linbit.com/drbd/

2.将下载到的源包传输到服务器，这里放在root用户根目录下

# ls /root/drbd-8.3.6.tar.gz

-rw-r--r-- 1 root root 457469 Nov 23 19:15 /root/drbd-8.3.6.tar.gz

3.解压源包

#tar xzf drbd-8.3.6.tar.gz

4.编译安装

# cd /root/drbd-8.3.6

#mkdir /usr/local/drbd

# ./configure --prefix=/usr/local/drbd/ --with-km

# make clean all install

# depmod –a

# modprobe drbd

# lsmod|grep drbd

drbd 270184 0

# cd /usr/local/drbd/

#ls

etc lib sbin share var

UNINSTALL

1.# modprobe -r drbd

2. # lsmod|grep drbd

3. # cd /root/drbd-8.3.6

4. # make uninstall

5. # cd /usr/local/drbd/

6.#rm –rf *

7.# vi /lib/modules/2.6.9-89.ELsmp/modules.dep

删除下面内容

/lib/modules/2.6.9-89.ELsmp/kernel/drivers/block/drbd.ko:

8.#删除/lib/modules/2.6.9-89.ELsmp/kernel/drivers/block/drbd.ko

说明：

1.8.3.6开始DRBD安装方式发生变化，目前官方文档未更新8.3.6安装文档，另uninstall脚本存在问题，无法清除安装内容。

2.8.3.6之前版本只需要make即可，无需configure操作。
