[drbd-mc] error while updating drbd ressource

[Lee Lists]

Hi,

I'm new to the lists and trying for the first time to connect to our production cluster based on :
- ubuntu 10.4
- corosync 1.2.8
- pacemaker 1.1.5
- drbd 8.3.7

And i get this message box while updating drbd ressource.

AppError.Text
release: 0.8.12
java: Sun Microsystems Inc. 1.6.0_22

uncaught exception
java.lang.NullPointerException
null
drbd.data.Cluster.contains(Cluster.java:225)
drbd.gui.ClusterBrowser.updateDrbdResources(ClusterBrowser.java:1566)
drbd.gui.ClusterBrowser.access$800(ClusterBrowser.java:110)
drbd.gui.ClusterBrowser$3.run(ClusterBrowser.java:759)
java.lang.Thread.run(Thread.java:662)

What can i do to sort this out ?

Thanks
Lee

After looking at the source code I didn't find support of floating addresses which we use.

resource r0-images {
device /dev/drbd0;
disk /dev/cvg/lv-images;
meta-disk internal;
floating 172.18.248.60:7788;
floating 172.18.248.61:7788;
}

Yes, you are right. This is not supported by DRBD MC yet.

What can I do to work around this ?
Any dirty hack ?

Can't think about anything right now, just to fix it in the Java code.
I'll try to do it in the next version.

Hi,

I've uploaded a new version

dmctest-0.8.13.dev.1.jar

in

http://oss.linbit.com/drbd-mc/

It doesn't solve the problem with DRBD setup, but at least it lets you use
the Pacemaker part of the GUI. So you shouldn't use the DRBD part for this
cluster for now.

Basically it needs a checkbox (floating) and then generate floating
keyword instead of address. Do you actually see this ip in the list of ips
in the address field?

To help you could contact sales at linbit.com and donate something. :)
