Don't know what "service check" means (guessing you mean what nanny does to decide a service is working?). But raising the issue of whether something below the level of what I thought I had changed was changed has been somewhat productive. While I can ping the realservers, turns out I can't access the services on them. Don't know why yet, but that's something I can investigate. (Still don't see why it changed when it did; but if I can't access the services from the lvs, then it can't route to them either, and the nanny checks will fail, etc., so that must be fixed before anything can work.) I will chase this down, and either fix it or have different questions :-). Thank you! > Do you have your IP addresses for different services on different devices Yes, they're on separate devices, and they're set up the same was as when it worked yesterday, so I don't think it's anything that basic that's wrong. I think I've been mis-understanding the startup order. Is this what really happens: 1. pulse started 2. lvsd started by pulse 3. nanny for each (active) realserver started by lvsd 4. When a nanny gets a successful test, either it or lvsd *then* enables that realserver for receiving traffic That would explain why I have nannys running, but no realservers listed by ipvsadm. I expected things to start out on, and only get turned off if the nannys failed; but in fact doing what I listed above makes more sense, it's better if you *have* a nanny to make sure the nanny reports ok *first*. -- David Dyer-Bennet, dd-b at dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info
