DNS Pool Members

gadbekr Understood on DNS. I mean that wherever your DNS records are configured for the FQDN that you are using as the pool member that is where I would set the TTL to 500 for future possible changes. Now in regards to the DNS TTL for the pool member using FQDN you should be able to follow these screenshots to point you in the right direction. I'm unsure when they changed it but the default use to be to use the TTL specified here in the node but it doesn't seem to be the default anymore and it now uses the TTL of the DNS record when it receives it but still worth checking. In this first screenshot you can see my pool configuration with the FQDN.

In the next screenshot you can see my node list with the two auto-generated nodes from the DNS query that happens when I added in www.example.com:80 as the pool member.

In this next screenshot you can see me going into node www.example.com with the arrow pointing at the TTL checkbox which when checked will use the TTL specified in the box to the right and if not checked will use the TTL that is returned in this case for www.example.com.

In this last window this shows you how to delete the auto nodes if you delete the FQDN node or if for some reason you still have old an new DNS records populated in the pool. You can only delete auto nodes through the CLI which is why you see that in the screenshot.

Hopefully this makes a bit more sense now and that I answered your question.
