Routes only need to be updated when IPs have moved. IP takeover runs will generate "ipreallocated", which is enough. "recovered" always follows "ipreallocated" anyway, so avoid the redundancy. Signed-off-by: Martin Schwenke <martin@meltin.net> (This used to be ctdb commit 1152215fc69217e4292762e28d193b7ea0e06ee3)

# script to add entries to the routing table after we have performed a
|
|
# take ip event
|
|
# (when we do a "releaseip" event and remove an ip address from an interface
|
|
# the kernel might automatically remove associated entries from
|
|
# the routing table. This is where we add them back)
|
|
#
|
|
# Routes to add are defined in /etc/ctdb/static-routes.
|
|
# Syntax is :
|
|
# IFACE NET/MASK GATEWAY
|
|
#
|
|
# Example
|
|
# bond1 10.3.3.0/24 10.0.0.1
