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
