9.3 Configuring the DRBD Service
NOTE: The following procedure uses the server names node 1 and node 2, and the cluster resource
name r0. It sets up node 1 as the primary node. Make sure to modify the instructions to use your own
node and file names.
1 Log in as the
root
user or equivalent on each node.
2
Open the
/etc/drbd.conf
file on the primary node (
node1
) in a text editor, modify the
following parameters in the
on hostname {}
sections, then save the file.
Š
hostname
Š
device
Š
disk
Š
address
Š
meta-disk
All of these options are explained in the examples in the
/usr/share/doc/packages/
drbd/drbd.conf
file and in the man page of
drbd.conf(5)
.
3
Copy the
/etc/drbd.conf
file to the
/etc/drbd.conf
location on the secondary server
(node 2).
scp /etc/drbd.conf <node 2> /etc
4 Initialize and start the drbd service on both systems by entering the following on each node:
rcdrbd start
5 Configure
node1
as the primary node by entering the following on
node1
:
drbdsetup /dev/drbd0 primary --do-what-I-say
NOTE: The --do-what-i-say option has been renamed to --overwrite-data-of-peer in the recent
versions of DRBD.
6 Check the DRBD service status by entering the following on each node:
rcdrbd status
Before proceeding, wait until the block devices on both nodes are fully synchronized. Repeat
the
rcdrbd status
command to follow the synchronization progress.
