I solve the problem just initializing DRBD with /etc/init.d/drbd start
in both nodes, but now I can't make it work with Proxmox. I feel like
the documentation is really messed up, don't know what I should do to
make a 3 node Cluster Proxmox with DRBD and LVM on top. It's confusing.
This is the steps that I've followed:
- Create volume group named drbdpool /dev/sdh1
- Initialize control volume drbdmanage init
- Add node
- Create logical volume with /lvcreate --name vmdisk --size 50G drbdpool
/on every node
- Create /etc/drbd.d/r0.res resource on every node with:
/resource r0 {//
// protocol C;//
// startup {//
// wfc-timeout 0; # non-zero wfc-timeout can be
dangerous
(http://forum.proxmox.com/threads/3465-Is-it-safe-to-use-wfc-timeout-in-DRBD-configuration)//
// degr-wfc-timeout 60;//
// become-primary-on both;//
// }//
// on node1 {//
// device /dev/drbd0;//
// disk /dev/drbdpool/vmdisk;//
// address 172.20.0.50:7788;//
// meta-disk internal;//
// }//
// on node2 {//
// device /dev/drbd0;//
// disk /dev/drbdpool/vmdisk;//
// address 172.20.0.52:7788;//
// meta-disk internal;//
// }//
//}//
/
- I try to create metadata with /drbadm create-md r0 /but I have an error:
*drbdadm create-md r0**
**drbd.d/drbdctrl.res:7: conflicting use of device-minor
'device-minor:node1:0' ...**
**drbd.d/r0.res:0: device-minor 'device-minor:node2:0' first used here**
*
I don't know what to do. I have restarted the nodes, reconfigured the
pool but I can't make it work.

Follow the steps in DRBD9 documentation carefully, in order to create
and initialise properly your DRBD9 cluster.
https://docs.linbit.com/docs/users-guide-9.0/#s-proxmox-overview
- Make sure you have installed properly drbd9 kernel modules/drbd-utils.
- Make sure you have created a VG named drbdpool *before* initialising
the cluster.
- Make sure you have configured /etc/drbdmanaged.cfg properly.

Hello,
I'm trying to setup DRBD9 in a new Proxmox 5.0 Cluster but I can't
make it work. I have read some threads like this but the solution
is not fully clear at all, so:
The problem is the following:
drbdmanage init
/You are going to initialize a new drbdmanage cluster.//
//CAUTION! Note that://
// * Any previous drbdmanage cluster information may be removed//
// * Any remaining resources managed by a previous drbdmanage
installation//
// that still exist on this system will no longer be managed by
drbdmanage//
//
//Confirm://
// yes/no: yes//
//*Error: External command failed:*//*
*//*drbdsetup new-resource .drbdctrl 0*//*
*//*Command output:*//*
*//* (stdout) *//*
*//*Command exited with exit_code 20*//*
*//*Initialization failed*/
I have installed the latest packages with: apt-get install
drbd-dkms dbrd-manager pve-headers etc and I have loaded the module
/ dkms status//
//drbd, 9.0.11-1: added/
modprobe drbd
# modinfo drbd

I don't know what to do anymore.
