[Linux-cluster] Node fencing via 'ssh/shutdown -r now' possible

GFS volumes will wait until fence reports back an exit status before
resuming activity. Running a shutdown command that could take 30+
seconds would be disastrous IMHO. It would lock up your cluster for
quite some time.

Hi all,

Has anybody an idea if it would be possible to fence first via a
controlled shutdown and if that one failed after a while go to the
second fencing via fence_impi?

The advantage would be, that the filesystem of the fenced node have a
better chance to be intact after shutdown then power cut off.
