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,

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

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.

Regards
Holger

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!

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