HI Dan,
My drbd version is 8.3.11. I configure Host A like you say.
[root at IVE151 ~]# cat /etc/drbd.d/r0.res
resource r0 {
on IVE151 {
device /dev/drbd0;
disk /dev/vg01/share;
address 2.2.2.151:7788;
meta-disk internal;
}
}
I have create meta-data successfully. Then I start drbd service , I got this message.
[root at IVE151 ~]# service drbd start
Starting DRBD resources: /etc/drbd.d/r0.res:1: in resource r0:
Missing section 'on <PEER> { ... }'.
resource r0: cannot change network config without knowing my peer.
[ d(r0) s(r0) ].
[root at IVE151 ~]# service drbd status
drbd driver loaded OK; device status:

This message shows that I cannot start drbd successfully. I think that you must configure peer node include node name, ip address, then you can start drbd service, right?

You mean that drbd server like Host A just care the configuration about itself, right? I'll try it later. Thank you!

The configurations SHOULD match to simplify maintenance, but server A will completely ignore server B settings, and server B will completely ignore server A settings. Your config is being read by the servers as:
Host A:
resource r0 {
on ME {
device /dev/drbd0;
disk /dev/vg01/share;
address 2.2.2.150:7788;
meta-disk internal;
}
}
and Host B is like this:
resource r0 {
on ME {
device /dev/drbd0;
disk /dev/vg02/share;
address 2.2.2.151:7788;
meta-disk internal;
}
}
Which is (I believe) what you wanted.

Subject: [DRBD-user] drbd wrong lower device doubt
Hi All, I have some doubts about drbd. I have configure two servers as Host A and Host B. Host A drbd configuration is like this:
resource r0 {
on A {
device /dev/drbd0;
disk /dev/vg01/share;
address 2.2.2.150:7788;
meta-disk internal;
}
on B {
device /dev/drbd0;
disk /dev/vg01/share;
address 2.2.2.151:7788;
meta-disk internal;
}
}
and Host B is like this:
resource r0 {
on A {
device /dev/drbd0;
disk /dev/vg02/share;
address 2.2.2.150:7788;
meta-disk internal;
}
on B {
device /dev/drbd0;
disk /dev/vg02/share;
address 2.2.2.151:7788;
meta-disk internal;
}
}
You can notice that Host A and Host B configuration file is not same. Actually Host A lower device is /dev/vg01/share and Host B lower device is /dev/vg02/share. The specified destination lower device is wrong in each server. Network setting is right . I set Host A disk state to UpToDate and Host B disk state inconsistent. I find that Host A is syncing to Host B. Why it can work regularly when I configure wrong lower device.
