Using haproxy 1.9.11
Would the fact that when I regenerate the haproxy file (if the servers doesnt match the same ordering), then i would send 503’s to the end-users for a short while? or it would be because of something else?
active and 1 backup servers left. 0 sessions active, 0 requeued, 0 remaining in queue. [WARNING] 273/061724 (9419) : backend ID mismatch: from server state file: '247', from running config '251' [WARNING] 273/061724 (9419) : Server xxxxxxx/yyyyyyy is DOWN, changed from server-state after a reload. 2 active and 1 backup servers left. 0 sessions active, 0 requeued, 0 remaining in queue.
In my backed i also use this:
default-server init-addr last,libc,none resolvers dns resolve-opts allow-dup-ip resolve-prefer ipv4
Note i am mostly using SRV / Service Discovery.
