1 Linux disk configuration
1
The Linux machine should better
has second disk, because we don’t want to sync the system partition.
2
The partition DRBD used to sync
should have same size.
3
The partition DRBD used must be
not mounted arbitrarily, because we need to mount the logical device of DRBD
not the physical disk.
2 Build the DRBD
This step will build the RPM package from
source code. It requires that the CPP compiler is installed on the machine.
1
Download the source code
.tar.gz from http://oss.linbit.com/drbd/
,
or if the Linux machine can connect to the internet, use “wget” down the source
code “wget http://oss.linbit.com/drbd/8.3/drbd-8.3.10.tar.gz
”,

4
Go to the /usr/src/redhat/RPMS/i386
dir, execute “rpm –i all” to install all rpm packages.
5
Edit the DRBD configuration
file, /etc/drbd.conf to following,
global { usage-count yes; }
common { syncer { rate 100M; } }
resource r0 {
protocol A;
net {
cram-hmac-alg sha1;
shared-secret
"cedrdb";
}
on rh56 {
device
/dev/drbd1; # the logical device, which
DRBD used
disk
/dev/sdb1;# the physical disk
address
192.168.70.253:7789;
meta-disk internal;
}
on cerh564 {
device
/dev/drbd1;
disk
/dev/sdb1;
address
192.168.70.251:7789;
meta-disk internal;
}
}
|
6
Do the same thing on another
machine.
3 Start the DRBD and test
1
Execute “drbdadm create-md r0”
to create the resource.
2
Execute “/etc/init.d/drbd start”
to start the drbd.
3
“drbdadm -- --overwrite-data-of-peer primary r0”
to change the machine to the primary machine.
4
“mount /dev/drbd1 /drbdtest” to
mount the DRBD device.
5
Execute “cat /proc/drbd” to
overview the status of the DRBD.
6
“drbdadm secondary r0” will
change the node to secondary, this command must executed after umount the
/dev/drbd1.
7
Make some file to dir /drbdtest
on the primary node, then change the secondary node to primary, and mount the
/dev/drbd1, you will find the file created on the primary node is on the
secondary node already.
8
Note on the first time DRBD
start, it will spend some time to sync the whole disk partition.
