Hi, I'm wondering that quorum server doesn't work, because Alan Robertson mentioned it in his LinuxWorld 08 talk. Can someone proof that it isn't working?
Third node solution: I wouldn't be able to use the third machine for more than one two-node cluster, right? best regards Robert -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Michael Schwartzkopff Sent: Donnerstag, 22.

You would have to build a third node and constraints to prevent resources running on that node. I would put the third node into a third location. Comments?
