Yes, I did visit them and they don't apply at all to this situation. The server is not heavily loaded. It is the Standby node and has nothing running on it. And the other link is for a split brain situation. That is also not the case here. Could you even be bothered to read and understand my question? >Anyways, if your intention was to test node failure, you should test >node failure, not total cluster communication breakdown aka split-brain, >which is what you do here. In my test I have disabled all network interfaces on the standby node, ie, effectively removed it from the network. How is that not simulating a node failure? And how is that split brain? The standby machine is totally off the network? Are you under the impression that when a machine has a hardware failure, that it can somehow magically still communicate on the network. Is that one of those magical invisible self powered NIC with an embedded os? Gotta get me one of those. >The only remotely useful thing heartbeat in haresources mode can >do to recover from a split brain is to stop everything, everywhere, and >restart from scratch. Again, I am not testing a split brain situation. I was asking if I there is a configuration setting that would not have the Primary Active Node restart if the Standby node fails. In other words, I want to configure the failover one way one time. Active to Standby with no failback, without the Active restarting no matter what happens to the Standby node. Is the architecture documented anywhere? I noticed there doesn't appear to be any diagrams in all these docs. Not on linux-ha.org, not in the User Guide, not in the docs that are part of this old version 2.1.4. Ever heard the phrase "A picture is worth a thousand words"? So Genius Lars, How would one test a node failure? Is that documented anywhere? Any that watermark on the http://linux-ha.org/FAQ#heavy_load page makes it unreadable. You want me to point out where to makes things clearer. Remove that ridiculous watermarking background. Lose the attitude on your replies. It is not appreciated and make you look like one of those weeny little nerds holed up in some dark room somewhere with no friends and who has never been on a date. _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
