Primary on both nodes

Hi all

I have the follow set of drbd nodes:

global { usage-count no; }
common {
syncer
{
rate 1000M;
}
}
resource r0 {
protocol C;
startup {
wfc-timeout 15;
degr-wfc-timeout 60;
become-primary-on both;
}
net {
cram-hmac-alg sha1;
shared-secret "drbd123";
allow-two-primaries;
after-sb-0pri discard-zero-changes;
after-sb-1pri discard-secondary;
after-sb-2pri disconnect;
}
on virt-00 {
device /dev/drbd0;
disk /dev/sda5;
address 10.0.0.1:7788;
meta-disk internal;
}
on virt-01 {
device /dev/drbd0;
disk /dev/sda7;
address 10.0.0.2:7788;
meta-disk internal;
}
}

Both node are identical.

But when I restart the nodes, I get both on StandAlone:

cat /proc/drbd
version: 8.3.3 (api:88/proto:86-91)
GIT-hash: 49bfeeaf3690ad0b9afd5376feda9e9eb34a30f3 build by
nobody [at] virt-0, 2009-11-25 16:09:37
0: cs:StandAlone ro:Primary/Unknown ds:UpToDate/DUnknown r----
ns:0 nr:0 dw:0 dr:220 al:0 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:b oos:0

The only way to return to Primary/Primary state, is running this command
on both nodes:

drbdadm -- --overwrite-data-of-peer primary r0

It is not perfect world for me.
I need both nodes become primary on boot time...

Perhaps I miss some configuration!! I don't know..

Thanks for any help

Hi,
any logs, just for start and understand?
Any iptables rules preventing communication on drbd port?

and messages on the other node in the mean time?
any other ones after 14:12:45?
what does it give the command
cat /proc/drbd
on both nodes at this point?
You should have
ro:Primary/Primary ds:UpToDate/UpToDate
right?
Now, when they are in sync in which order do you stop and then start the nodes?
And what are the messages on one node when you shutdown the other one?

Re: Primary on both nodes [In reply to]

Ok

Now I halt both node ok???

The
I am on virt-00, that is my node0 here.
I use this command:

cat /proc/drbd

and get this:

And on virt-01, that is my node1 here, I get this:

No, it is not good.
In the first post you said that after
drbdadm -- --overwrite-data-of-peer primary r0

you was ok.
"Ok" here means that on both you have, after command above completes,
something like
cs:connected ro:Primary/Primary ds:UpToDate/UpToDate

Is this so? Otherwise it is not good..

Don't use Gentoo ;)

No, actually I meant,
double check your init script.

You are aware that only the init script takes care of the

Re: Primary on both nodes (SOLVED) [In reply to]

Hi folks

I found a missconfiguration here...

Apparently, DRBD do not work properly with bridge devices... ( that is
correct?)

I was use br1 to dedicates device between nodes...

I disable bridge and use 'real' device and now evertything is going right...

But, to my project here, I really need bridge devices because inside a
VM that I deploy with KVM, I use DRBD too, and the DRBD use a bridge
device use by DRBD on real server....

The IP of br1 on real server is the same range on VM, to communcate with
other VM...

Re: Primary on both nodes (SOLVED) [In reply to]

Just a supplement

Now, when I reboot the both machines, I get this message on secondary node:

block drbd0: short read expecting header on sock:r=0

What this meaning???

This may not help, but at least it breaks the silence. :)

I've not used DRBD in a VM, but I do use it between dom0s via a real
switch and I use bridging between a set of VMs. As I've gotten my system
set up, my bridges don't have IPs themselves. In this configuration,
they are essentially just switches... Not addressable devices.

So what I am wondering is; Could your problem be a mis-configuration on
the networking instead of an actual problem with DRBD? To be honest, and
I am no expert, I don't see how the difference between real and virtual
switches/bridges should affect DRBD at all.

Lol, sorry. Out of habit I hit ctrl+alt+r when replying to lists that
default replies to the author instead of the list. I usually neglect to
remove individual senders. Sorry for the line noise.
