Description Sébastien BONNET 2002-11-18 14:41:42 UTC
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 :(

Comment 1 Mike McLean 2002-11-25 15:59:01 UTC
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.
