Hi,

I'm new to drbd and fairly new to Centos, I am trying to setup a NFS
server using heartbeat.

I managed to get drbd to work using a simple setup of 2 drives on
different machines, but when I add a further 2 drives I run into this
error on.

Starting DRBD resources:    [ d0 d1 ioctl(,SET_DISK_CONFIG,) failed:
Invalid argument
Lower device is already mounted.

cmd /sbin/drbdsetup /dev/drbd1 disk /dev/hdd1 internal -1  failed!

As far as I can tell, hdd1 is not mounted, there is no reference to it in
fstab etc. - It is a new partition that I created just before running drbd
and it is not listed in response to mount.

The simple drbd.conf I am trying is below.

Any suggestions on how to fix this would be gratefully received.

Rob

resource drbd0 {
  protocol C;
  syncer        {
  rate 12M;
  }

  on fs1.bathnetworks.local {
    device      /dev/drbd0;
    disk        /dev/hde1;
    address     10.0.0.1:7788;
    meta-disk internal;
  }

  on shorty.bathnetworks.local {
    device      /dev/drbd0;
    disk        /dev/hdc1;
    address     10.0.0.2:7788;
    meta-disk internal;
  }
}
resource drbd1 {
  protocol C;
  syncer        {
  rate 12M;
  }

  on fs1.bathnetworks.local {
    device      /dev/drbd1;
    disk        /dev/hdf1;
    address     10.0.0.1:7789;
    meta-disk internal;
  }

  on shorty.bathnetworks.local {
    device      /dev/drbd1;
    disk        /dev/hdd1;
    address     10.0.0.2:7789;
    meta-disk internal;
  }
}
