Proxmox 4.x Jessie 8.2 - drbd global_common.conf

[ssaman]

Hello,

I have a problem, when i try to execute.

drbdadm create-md res-node1

i get this output

drbd.d/res-node2.res:1: conflicting use of resource section 'res-node1' ...
drbd.d/res-node1.res:1: resource section 'res-node1' first used here.

my global_common.conf looks like this similar to wiki/DRBD#Prepare_drbd_configuration :

global { usage-count no; }
common { syncer { rate 30M; verify-alg md5; }

i think its because of the new version of drbd - my current version is 8.9.4-1

EDIT:
this is my res-node1

resource res-node1 {
  protocol C;
  startup {
    wfc-timeout  0;
    degr-wfc-timeout 60;
    become-primary-on both;
  }
  net {
    cram-hmac-alg sha1;
    shared-secret "xxxxxxxxxxxxx";
    allow-two-primaries;
    after-sb-0pri discard-zero-changes;
    after-sb-1pri discard-secondary;
    after-sb-2pri disconnect;
  }
  on pve4-node1 {
    device /dev/drbd0;
    disk /dev/sdb1;
    address 10.0.0.1:7788;
    meta-disk internal;
  }
  on pve4-node2 {
    device /dev/drbd0;
    disk /dev/sdb1;
    address 10.0.0.2:7788;
    meta-disk internal;
  }
}

the version number is misleading, you got the right one.

thanks you

I have one more question.
is it possible to run drbd "9" in dual primary mode or does it already use it?

if i run

drbdmanage list-nodes

it shows at my first node

EDIT:

after that i created a new VM - the command

drbdmanage list-nodes

shows
