[ClusterLabs] How to fence cluster node when SAN filesystem fail

[Ken Gaillot]

Hi,

Upstream documentation on fencing in Pacemaker is available at:

http://clusterlabs.org/doc/en-US/Pacemaker/1.1-pcs/html-single/Pacemaker_Explained/index.html#idm139683949958512

Higher-level tools such as crm shell and pcs make it easier; see their
man pages and other documentation for details.
