rcdrbd status
Before proceeding, wait until the block devices on both nodes are fully synchro-
nized. Repeat the
rcdrbd status
command to follow the synchronization
progress.
9 After the block devices on both nodes are fully synchronized, format the DRBD
device on the primary with a file system such as reiserfs. Any Linux file system
can be used. For example, enter
mkfs.reiserfs -f /dev/drbd0
IMPORTANT
Always use the
/dev/drbd<n>
name in the command, not the actual
/dev/disk
device name.
14.3 Testing the DRBD Service
If the install and configuration procedures worked as expected, you are ready to run a
basic test of the DRBD functionality. This test also helps with understanding how the
software works.

Test the DRBD service on node 1.
1a

root
.
1b
Create a mount point on node 1, such as
/srv/r0mount
.
mkdir -p /srv/r0mount
1c
Mount the
drbd
device.
mount -o rw /dev/drbd0 /srv/r0mount
