Hi all,
I'm not familiar with pacemaker and corosync.
And since it's first time to post here, I'm not sure if I may ask my
question here.
It maight be primitive question.
Please let me know if I should ask at other place.

My questions is for manual failover of shared IP.

I have a test environments which share an IP by pacemaker and corosync.
It's almost no load.
Now I'm testing manual failover of Shared IP repeatedly.


The downtime of the Shared IP is just a couple of seconds normally.
But I sometimes encounter long down time when doing manual failover of
shared IP.
It takes about 90 sec.

Does anyone know possbile cause why such adowntime of Shared IP happen
during manual failover?
