Thank you to all who helped me here,
I finally have my three nodes syncing and can breath a little more
freely. Your patience with me as I kept missing what was in front of me
is appreciated.
in gratitude

Thanks Johanne,
indeed this one of three hosts was running 8.4 kernel module, the
example parses on the other hosts. Thanks for that, I was sure I had
9.1 on them all.
Very much appreciated

You probably have a DRBD 8 kernel module loaded, then drbdadm parses
the configuration in v8 format which doesn't have node-id.
Hope that helps,

Can I convince anyone to show me a working res file for the V9 3
node setup with multiple NICs and direct connections?
Try as I may I simply cannot get my res file to parse.
I even tried doing it all on the one network as per the first
example but I can't even get the examples to parse, a copy/paste
of the 3 node example complains that "connection-mesh" in in the
wrong place. I figured I would take a working example and go
from there but even then I get:
drbd.d/webdav.res:7: Parse error: 'disk | device | address |
meta-disk | flexible-meta-disk' expected,
but got 'node-id'
so I can't even seem to get the right structure and I am clearly
missing something fundamental here...
Does anyone have any suggestions?

Hi guys,
sorry to keep bugging you with this. Can anyone give me a
sample working res file for a 3 node setup with crossover links?
It says here
https://linbit.com/drbd-user-guide/drbd-guide-9_0-en/#s-drbdconf-conns
<https://linbit.com/drbd-user-guide/drbd-guide-9_0-en/#s-drbdconf-conns>
:
"If you have got enough network cards in your servers, you can
create direct cross-over links between server pairs. A single
four-port ethernet card allows to have a single management
interface, and to connect 3 other servers, to get a full mesh
for 4 cluster nodes."
I do, and each of the three nodes can ping the other two nodes
to which they are connect. But I am confused about how/where
their IPs and ports are defined in the .res file. I have
three hosts connected directly via discrete interfaces on each
node.:
01 <----> 02 ---- 10.10.1.0/24
02 <----> 03 ---- 10.10.2.0/24
01 <----> 03 ---- 10.10.3.0/24
back to the page is then says this:
In this case you can specify a different IP address to use the
direct link:
resource r0 {
...
connection {
host alice address 10.1.2.1:7010;
host bob address 10.1.2.2:7001;
}
connection {
host alice address 10.1.3.1:7020;
host charlie address 10.1.3.2:7002;
}
connection {
host bob address 10.1.4.1:7021;
host charlie address 10.1.4.2:7012;
}
}
I assume the ... on line 2 is referring to the previous example
above that, which is:
resource r0 {
device /dev/drbd1;
disk /dev/sda7;
meta-disk internal;
on alice {
address 10.1.1.31:7000;
node-id 0;
}
on bob {
address 10.1.1.32:7000;
node-id 1;
}
on charlie {
address 10.1.1.33:7000;
node-id 2;
}
connection-mesh {
hosts alice bob charlie;
}
}
But I keep getting parsing errors no matter where I put that "connection"
stanza. drbdadm complains with:
# drbdadm up webdav
drbd.d/webdav.res:18: Parse error: 'protocol | on | disk | net | syncer |
startup | handlers | ignore-on | stacked-on-top-of' expected,
but got 'connection' (TK 282)
I do apologize if I am again asking a question the answer to which is right in front
of my face and I'm not seeing it, but where do the three "connection"
statements go? Obviously they don't go where I put them.
What would a complete example of a 3 node V9 with a discrete NIC and cable
between each node look like?
Please and thanks and sorry to be asking such a newb question. :(
Paul
