Persist Hash CARP with Ratio or weight

not sure if it is a good idea but I think you can try something like

 

- adding ip alias on servers. for example if you want to double traffic on new server, you may add 1 more IP (or port) and add that as new member. so your pool configuration may look like

 

pool x member {

 

1.1.1.1:80

 

1.1.1.2:80

 

1.1.1.3:80

 

1.1.1.3:81

 

}

 

i think disadvantage of this method is it may not good if you need ratio like 8:9

 

.

 

- another idea is to have a fake pool member ip and reselect it to the right one in LB_SELECTED (or LB_FAILED)

 

 

let say, you have only 2 server 1.1.1.1 and 1.1.1.2, you may add 2 more fake ip to archive 3:1 ratio

 

 

pool x member {

 

1.1.1.1:80

 

1.1.1.2:80

 

1.101.1.1:82 (fake ip)

 

1.101.1.1:83 (fake ip)

 

}

 

 

then in LB_SELECTED, reselect it to actual one

 

 

if { [LB::server addr] eq "1.101.1.1" } {

 

LB::reselect pool x member 1.1.1.1:80

 

}

 

 

these ideas are not tested.
