Hi.

I could not find anything "googleing" rcd_serial.
Do you have a link where I could get more information about it?

About my last big message the most important question is:
can I use iSCSI powered by drbd for sbd fencing?
is it a good solution?
what kind of iSCSI: active/active or active/passive?
any other hint for this solution?

Regards,
Gilsberty

Hello.

I'm reading tons of information about pacemaker/corosyc/drbd and fence
devices and right now I'm feeling really lost.

My enviroment (2 nodes cluster-corosync/pacemaker for kvm virtualization
using drbd as shared storage) doesn't have a true fence device (ipmi,
apc or any other physical device/hardware).

In fact I could use my managed switch but this method would cut only the
node's external link (the one where the services/vms will be avaliable)
and not the drbd's internal link (for this connection I'm using a direct
crossover cable).
And thats it! That is all I got for a production environment.

So... how to do the fencing/stonith?
You can think about rcd_serial.
