Open Stack

Hi,

I think I found out the issue, as I have all the 3 nodes running Keepalived
as MASTER, when I reboot one of the servers, one of the VIPS failsover to
it, causing the timeout issues. So I left only one server as MASTER and the
other 2 as BACKUP, and If I reboot the BACKUP servers everything will work
fine.

As a note aside, I don't know if this is some ARP issue because I have a
similar problem with Neutron L3 running in HA Mode. If I reboot the server
that is running as MASTER I loose connection to my floating IPS because the
switch doesn't know yet that the Mac Addr has changed. To everything start
working I have to ping an outside host  like google from an instance.

Maybe someone could share some experience on this,

Thank you for your help.
