The test file does not get created, and I can’t see where any errors might be being logged to. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I’ve tested this configuration by disabling a switch port. The second node picks up the services correctly, but the first node keeps on running them too, and does not notice that it no longer has a writeable filesystem. If the port is reconnected, they both have the same ext3 filesystem mounted at once, which makes a fine mess.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Here’s my current configuration.
