[DRBD-user] DRBD + LVM2 Setup on RHEL5.1

[Chris Raver]

I'm having a difficult time setting up DRBD and LVM2 on Redhat Enterprise Linux 5.1.   I've installed DRBD82 and KMOD-DRBD82 via the CentOS 5.1 repo using yum and I've also compiled and installed the module from source using the correct kernel source, I get the same result either way.  I created my drbd.conf file below but starting the service fails and so does running pvcreate to create my physical volume.  I've been working on this for a couple days with no success. Can someone here point me in the right direction?

Starting drbd:

/etc/init.d/drbd start
Starting DRBD resources:    [ d(r0) Can not open device '/dev/drbd/r0': No such file or directory

[r0] cmd /sbin/drbdsetup /dev/drbd0 disk /dev/drbd/r0 /dev/drbd/r0 internal --set-defaults --create-device --on-io-error=detach  failed - continuing!

n(r0) ].
[root at qa1r2cls drbd-8.2.5]#

drbd.conf file:

resource r0 {
  protocol C;

  startup {
    degr-wfc-timeout 90;
  }

  disk {
    on-io-error   detach;
  }

  on qa1r2cls {
    device /dev/drbd0;
    disk /dev/drbd/r0;
    meta-disk internal;
    address 192.168.50.202:7789;
  }
  on qa1r3cls {
    device /dev/drbd0;
    disk /dev/drbd/r0;
    meta-disk internal;
    address 192.168.50.203:7789;
  }
}

pvcreate error:

[root at qa1r2cls drbd-8.2.5]# pvcreate -d -v -ff /dev/drbd0
    Wiping cache of LVM-capable devices
    Wiping internal VG cache
  Device /dev/drbd0 not found (or ignored by filtering).

lvm.conf filter:

filter = [ "r|.*|", "a|/dev/drbd[0-9]$|" ]


Thanks
