[Linux-ha-dev] [Pacemaker] A patch for stonith external/libvirt

[Dejan Muhamedagic]

Hi Owen,

I attach a patch for the stonith agent external/libvirt. This agent
was failing on our machines because for rebooting machines it tried to
stop and then start them, which doesn't work on our system, while
rebooting them does. We have cluster glue version 1.0.8-2 installed
on a Debian system, with libvirt 0.9.12-3.

It would be good to have both, i.e. on-off and reboot method.
With a parameter which would specify the method. I wonder why
didn't the author put reboot in the first place. Holger?

Cheers,

Dejan

P.S. Moving discussion to linux-ha-dev.

I modified the patch and introduced a reset_method parameter. It
defaults to power_cycle, so the default behaviour remains the
same.

Many thanks for the patch!

Dejan,
I'm no longer in "the cluster business".
I can not recall the reason but I suspect in my configuration nearly 2
years ago it was the other way round:
reboot did not work but stop/start did.

Holger

Good luck!

OK. The script supports the reboot method, but it still power
cycles by default.
