Nimbostratusdisable persistens for a specific node
hello,
i have a little irule problem. here the relevant config -->
pool xyz_POOL_80 {
lb method predictive
min active members 1
monitor all cm_generator
member 10.48.15.111:http priority 2
member 10.48.15.112:http priority 2
member 10.48.15.121:http priority 2
member 10.48.15.122:http priority 2
member 10.48.16.90:http monitor none
}
rule np01 {
when LB_SELECTED {
if { [ [LB::server addr] equals 10.48.16.90 ] } {
persist non }
}
virtual xyz_VIP_80 {
destination 192.168.2.2:http
fallback persist source_addr
ip protocol tcp
profile http tcp
persist cookie
pool xyz_POOL_80
rule np01
}
... the member 10.48.16.90 is my failure server, triggert over the priority. drawback of this solution is that in the failure case the clients directed to the failure server have a source_addr persistens too. if the priority 2 servers recovered, this clients will directed to the failure server anymore because the source_addr persistens. :-(
i thought i can solve this drawback with the irule np01. now my box responds to any request with a reset.
... help me please.
- Andreas,
Be sure that you're spelling every part of the rule correctly. It looks like you've got the general idea correct, but it could be that you're missing an "e" on none.
The other thing I noticed is that you were using an extra set of brackets where they weren't needed.
Try:when LB_SELECTED { if { [LB::server addr] equals 10.48.16.90 } { persist none } }
Other than that, it looks pretty straight-forward.
Hope that helps,
-Colin
