Description Niels de Vos 2016-06-26 16:41:17 UTC

Description of problem:
The network authentication checks in the tests/basic/mount-nfs-auth.t test depend on resolvable hostnames. When the test runs, the configuration is updated to allow/deny connections from $H0 (hostname --fqdn).

In the case of running the tests in Vagrant with the ./run-tests-in-vagrant.sh script, the VMs do not get a resolvable IP address. The problem arises when the NFS-client connects to the Gluster/NFS server, and the server resolves the hostname of the client based on the IP-address. If the IP-address does not resolve to the configured $H0 hostname, access is denied and the testcase fails.

Version-Release number of selected component (if applicable):
mainline and 3.8

How reproducible:
100%

Steps to Reproduce:
1. run ./run-tests-in-vagrant.sh
2. see mount-nfs-auth.t fail

Actual results:
mount-nfs-auth.t fails

Expected results:
mount-nfs-auth.t should pass

Additional info:
Bug 1350237 has been filed for a related problem that has been found while running the ./run-tests-in-vagrant.sh script.

Comment 1 Niels de Vos 2016-06-27 09:11:24 UTC

Comment #1 in bug 1350237 has steps that I used in a VM to setup a DNS server for itself. Maybe this approach can be taken, or maybe there is a Vagrant plugin that can configure DNS correctly?

https://bugzilla.redhat.com/show_bug.cgi?id=1350237#c1 because I dont know how to make Bugzilla render the link... Like bug 1350237#c1 maybe?

I think Vagrant on libvirt should provide you all you need.
If not, I assume using Ansible could solve this.

Comment 4 Amar Tumballi 2019-05-09 19:58:51 UTC

These things are now fixed as we work with regression scripts properly in recent times (ie, haven't seen issues like this in a long time). Please feel free to reopen if still an issue.
