Some of you on the list might remember my problem concerning our DNS cluster last year.
http://archive.linuxvirtualserver.org/html/lvs-users/2006-11/msg00278.html These problems (DNS timeouts) have continued throughout this year and i have been desperately trying to find the solution. I have been folowing the mailing list and stumbled over the probems Adrian Chapela was having with his DNS setup. Which brought me to the solution ipvsadm -L --timeout the default settings for UDP packets was set to 500 seconds which should be changed. Which is way to long the load balancers were waiting for 5 minutes to timeout a UDP packet i get ablout 1500 queries a second. I changed the setting to 15 seconds last week. And moved some of our old windows/bind DNS servers to the new linux DNS cluster. Before i changed the timeout settings i always recieved a call from our customers within two hours your DNS services are not responding correctly. The IP's that refused to answer would always change i have 254 IP's some of the large German dialup providers would refuse to talk to us which resulted in domains not being reachable. Our DNS cluster is autorative for about 250000 domains so you can imagine how many complaints i recieved. I was about to give up and scrap keepalived i am so glad i did not. Changing the timeout value solved my problems and i am a happy man at the moment. Is there a way to set the timeout value permently so it is saved after a reboot of the server? One last thing i would like to say is a big thank you to Graeme Fowler, Horms, Adrian Chapela and Alexandre Cassen for writing this grat piece of software. and anyone else on the list who maybe contributed to help me finaly find the solution. Thank you guys you do a great job on the mailing list.
