Hi Rasto,<br><br>Great update! Thanks for this.<br><br>1. Could you explain how to try the LVM plugins? I saw beta versions of them on the drbd-mc website a while ago but now they are removed again.<br><br>2. enable fine-grained sudo, don't make everything in bash -c<br>
<br>I'm using sudo too, can you explain what changed here? I don't need /bin/bash anymore in /etc/sudoers now, what commands are needed in /etc/sudoers?<br><br clear="all">
Kind regards,<br><br>Caspar Smit<br><br><div class="gmail_quote">2011/4/29 Rasto Levrinc <span dir="ltr"><<a href="mailto:rasto.levrinc@linbit.com" target="_blank">rasto.levrinc@linbit.com</a>></span><br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
Hi,<br>
<br>
This is the next DRBD MC release 0.9.2. DRBD MC is DRBD, Pacemaker and<br>
cluster virtual manager GUI.<br>
<br>
In this release the parts of the GUI that enable to setup a live VM<br>
migration were enhanced and fixed. The virtual manager works now in a<br>
cluster as promised.<br>
<br>
Another nice feature, that someone can combine with the previous, is the<br>
possibility to create LVs, resize them, snapshot them etc.<br>
<br>
Just think about it...<br>
LVM -> DRBD -> HB/Corosync+Pacemaker -> VMs -> live migration, it comes<br>
all together. Now, there's an idea for the next video. :)<br>
<br>
You can get DRBD MC here:<br>
<a href="http://oss.linbit.com/drbd-mc/" target="_blank">http://oss.linbit.com/drbd-mc/</a><br>
<a href="http://oss.linbit.com/drbd-mc/DMC-0.9.2.jar" target="_blank">http://oss.linbit.com/drbd-mc/DMC-0.9.2.jar</a><br>
<a href="http://oss.linbit.com/drbd-mc/drbd-mc-0.9.2.tar.gz" target="_blank">http://oss.linbit.com/drbd-mc/drbd-mc-0.9.2.tar.gz</a><br>
<br>
1. You don't need Java on the cluster servers only on your desktop.<br>
2. Download the DMC-0.9.2.jar file.<br>
3. Make sure you use SUN Java not the OpenJDK 1.6.<br>
4. Start it: java -jar DMC-0.9.2.jar<br>
5. It connects to the cluster via SSH.<br>
6. If you use it without DRBD, you have to click "Skip" button on couple of<br>
places.<br>
<br>
DRBD MC is compatible with Heartbeat 2.1.3 to the Pacemaker 1.1.5 with<br>
Corosync or Heartbeat and DRBD 8.<br>
