First confirm whether the heartbeat status is normal and whether there is a secondary IP
[root@data-1-1 data]# ip add|egrep “0.17|0.18”
inet 10.0.0.17/24 brd 10.0.0.255 scope global secondary eth0
[root@data-1-2 /]# ip add|egrep “0.17|0.18”
< p> inet 10.0.0.18/24 brd 10.0.0.255 scope global secondary eth0
Stop one StationdrbdHigh availability and view:
[root@data-1-1 data]# ip add |egrep “0.17|0.18”
[root@data-1-1 data]#
[root@data-1-2 /]# ip add|egrep “0.17|0.18”
inet 10.0.0.18/24 brd 10.0.0.255 scope global secondary eth0
inet 10.0.0.17/24 brd 10.0.0.255 scope global secondary eth0
[root@data-1-2 /]#
Check the drbd status of the two machines:
[root@data-1-1 /]# cat /proc/drbd
version: 8.4.6 (api:1/proto:86-101)

The display result is slave—-slave status

Now you need to manage drbd through heartbeat, and to promote one of them to the main status, you need to modify the /etc/ha.d/haresources file
[ root@data-1-1 /]# cat /etc/ha.d/haresources
data-1-1 drbddisk::data IPaddr::10.0.0.17/24/eth0
< p>data-1-2 IPaddr::10.0.0.18/24/eth0
[root@data-1-2 /]# cat /etc/ha .d/haresources
data-1-1 drbddisk::data IPaddr::10.0.0.17/24/eth0
data-1-2 IPaddr::10.0.0.18/24/eth0
Then restart the heartbeat program:
[root@data-1-1 /]# /etc/init.d/heartbeat restart

Check status:
[root@data-1-1 /]# cat /proc/drbd

drbdTo start well, both roles should besecondaryWhen you start heartbeat, it can help you choose the master:
according to/etc/ha.d/haresourcesinside The parameters you setdrbddisk::data to choose.
Automatically mount /dev/drbd0, you need to configure parameters in /etc/ha.d/haresources
[root@data-1-2 ~]# cat /etc/ha.d/haresources
data-1-1 drbddisk::data Filesystem::/dev/drbd0::/data::ext4 IPaddr::10.0.0.17/24/eth0
data-1-2 IPaddr ::10.0.0.18/24/eth0
