14.4.1 Configuration
If the initial
drbd
setup does not work as expected, there is probably something wrong
with your configuration.
To get information about the configuration:
1
Open a terminal console, then log in as
root
.
2
Test the configuration file by running
drbdadm
with the
-d
option. Enter
drbdadm -d adjust r0
In a dry run of the
adjust
option,
drbdadm
compares the actual configuration
of the DRBD resource with your DRBD configuration file, but it does not execute
the calls. Review the output to make sure you know the source and cause of any
errors.
3
If there are errors in the
drbd.conf
file, correct them before continuing.
4
If the partitions and settings are correct, run
drbdadm
again without the
-d
option.
drbdadm adjust r0
This applies the configuration file to the DRBD resource.
14.4.2 Hostnames
For DRBD, hostnames are case sensitive (
Node0
would be a different host than
node0
).
If you have several network devices and want to use a dedicated network device, the
hostname will likely not resolve to the used ip address. In this case, use the parameter
disable-ip-verification
.
