DRBD - no resources defined

Question

I have some problems getting a drbd cluster running.

When I want to start creating my storage, i get the following error:

root@raspberrypi-ha1~# drbdadm create-md drbd1
no resources defined

But my resource is definitely defined in /etc/drbd.conf on both hosts:

include "drbd.d/global_common.conf";
include "drbd.d/*.res";

resource drbd1{
        protocol C;

        syncer {
        rate 3M;
        al-extents 257;
}
on raspberrypi-ha1 {
    device    /dev/drbd1;
    disk      /dev/sda1;
    address   192.168.178.201:7789;
    meta-disk internal;
  }
  on raspberrypi-ha2 {
    device    /dev/drbd1;
    disk      /dev/sda1;
    address   192.168.178.202:7789;
    meta-disk internal;
  }

}

The hostname is set to raspberrypi-ha1 Does anyone have an idea?

Answer 1

I had the same issue. The fix is quite simple actually. Typically this happens when you update your drbdutils package to version 8.9.6. The configuration file is now in /usr/local/etc/drbd.conf NOT /etc/drbd.conf

Typically the /usr/local/etc/drbd.conf just says to include the file /usr/local/etc/drbd.d/global_common.conf and /usr/local/etc/drbd.d/*.res

So all you need to do is move your config files to the new location. I would remove /etc/drbd.conf and /etc/drbd.d to avoid confusion in the future.

Another very useful command and the one I used to determine the problem is:

drbdadm dump --config-to-test=/dev/null

which dumps the configuration as is.

It looks like there is no space between the resource name (drbd1) and the open bracket; perhaps this is a problem.

Also, DRBD needs the hostnames in your configuration to match exactly what is shown with: $ uname -n
