I can even set the arp_announce and arp_ignore remotely so now
everything is in just two config files:
keepalived.conf and ip_localhost
I have found that when needing to recycle keepalived that the order of
starting and stopping seems to matter. The most reliable way I have
found is:
service keepalived stop (backup director)
service keepalived stop (master director)
service keepalived start (master director)
service keepalived start (backup director)
otherwise LVS seems to get confused and there ends up being no entries
in the LVS table. Maybe this is related to how I am configuring
keepalived but I wouldn't think setting the VIP on the real servers
would affect the LVS table.
