Description of Problem: It sometimes happens that a fail-over interface is not removed when pulse is stopped ("ifconfig ethN:X down" not run). This can create BIG problems when running with both a master and a backup director (resulting in having the VIP on both directors). Version-Release number of selected component (if applicable): piranha 0.7.0-3 How Reproducible: In my setup it was quite often, but it could be just 1 time out of 100 :( Steps to Reproduce: 1. pulse -v -c /etc/sysconfig/ha/lvs.cf 2. wait a few seconds 3. service pulse stop 4. ifconfig might show the VIP whereas it should not Actual Results: VIP configured on director whereas service not running, or worse, running on backup director. Expected Results: VIP removed when pulse stoppped. Additional Information: The problem *seems* to be in pulse.c, in function deactivateFos. Swapping the HA_process termination and the VIP cleanup *seems* to be a fix. But not a real explaination :(
Piranha's FOS functionality (though not piranha itself) is slated for removal. There are much better two node failover solutions out there, notably Red Hat Cluster Manager.
