DnsServers does not set resolvers properly

[Cédric Jeanneret deactivated]

Dear Stackers,

Apparently, there's an issue with the DnsServers parameters: it doesn't set the resolvers as expected.

Currently, we're deploying Pike on CentOS 7, and we're pushing three resolvers (our freeIPA servers).
Unfortunately, it seems only one resolver is added instead of three (ok, two, because RHEL systems don't support three).

Is it a known issue due to the said limitation on RHEL family? Shall we put only two resolvers in the parameter?

It would be great to tackle that one quickly, having only one resolver isn't really reliable (we detected that issue when the ipa instance went down a night…).

Thank you in advance !

Cheers,

C.

Ah, should have opened that one in os-net-config project maybe? As the ifcfg* files in /etc/sysconfig/network-scripts are generated by that python lib/script…

Note: I'd rather put a "high" importance for that kind of thing, as it might prevent a good deploy of the overcloud (and the undercloud, as it uses the same process).

Cheers,

C.

Hello,

Small update: setting only two resolver in the environment file does set them up both as expected.

Cheers,

C.

    Allow to pass more than two DNS while putting 2 DNS

    Until now, when we pass more than 2 DNS, only the first one is added in
    the ifcg-* config files.

    This patch-set proves the issue, and proves the correction actually works.
