[drbd-mc] DMC: DRBD cluster in 10 minutes

[Rasto Levrinc]

Hi,

this is my first screencast about DMC and my first screencast in general
and it's purpose is give you quick glance what is DMC about.

It is about installing, configuring, administrating and operating a DRBD +
Heartbeat + Pacemaker cluster and experiencing an unexpected failover in
about 10 minutes, if you don't count coffee pauses. Don't worry I've
edited most of the waiting, boiling, slurping, flushing etc. parts out.

This is going to steal about 9 minutes of your life and nobody is going to
give it to you back. The coolest part is from the 8th minute till the end.

During which I hear, "I would choose Heartbeat, and so should you."
Can you expand on that? I seem to recall seeing MC state Heartbeat is
stable, but not maintained and Corosync is the future.

AFAIK Linbit maintains and recommends Heartbeat over Corosync at this
time. Corosync is missing some important features for what is usually
considered normal for HA cluster. So it's your call. :) MC supports both.

What if I start the cluster with only one host? That seems to not be
an option for DRBD MC.
My use case is a xen domU with DRBD storage.

thanks,

That should work, you just create a one node cluster. Or at which point
did you get stuck?

Of course, it worked fine when I got back in to find out!

thanks anyway,
