Last modified: 2014-01-21 14:48:10 EST
Description of problem: It should not accept the configurations when it is actually fail in Kdump. There are serial scenarios: 1. Provide an unreachable location when configure Kdump with NFS type.(nfs-unreachable-host.png) 2. Provide an unreachable location when configure Kdump with SSH type.(ssh-unreachable-host.png) 3. Provide an error password when configure Kdump with SSH type.(provide-error-password-1.png&provide-error-password-2.png) Version-Release number of selected component (if applicable): rhev-hypervisor6-6.5-20130725.0.el6 ovirt-node-3.0.0-6.1.el6.noarch How reproducible: 100% Steps to Reproduce: 1. Enter unreachable location in NFS type like "10:/123". 2. Enter unreachable location in SSH type like "root@10". 3. Provide an error password three times in validation in SSH type. Actual results: 1. After step1, it persisted the configuration in TUI and /etc/kdump.conf file. 2. After step2, it persisted the configuration in TUI and /etc/kdump.conf file. 3. After step3, it persisted the configuration in TUI and /etc/kdump.conf file. Expected results: 1.It should not accept the error configuration when providing an error location. 2.It should not persist the configuration when failed valid the password. Additional info:
Created attachment 781900 [details] error configurations
Test version: rhevh-6.5-20131024.1.0.iso ovirt-node-3.0.1-6.el6.noarch Test steps: 1. Clear install rhevh-6.5-20131024.1.0.iso. 2. Enter unreachable location in NFS type like "10:/". 3. Enter unreachable location in SSH type like "root@10". 4. Provide an error password three times in validation in SSH type. Test result： 1. After step2/3/4, it will prompt like the follows. An error occurred KDump configuration failed, location unreachable. Previous configuration was restored. 2. After step2/3/4, it not persisted the configuration in /etc/kdump.conf file. 3. But after step2/3/4, it save the error configuration in TUI. The error configuration should not be saved in TUI also. So this bug is not fixed totally. Change the status from ON_QA to ASSIGNED.
Test version: rhev-hypervisor6-6.5-20131031.1 ovirt-node-3.0.1-7.el6.noarch Test steps: 1. Clear install rhevh-6.5-20131031.1.0.iso. 2. Enter unreachable location in NFS type like "10:/". Test result： 1. After step2, it report as follows. An error appeared in the UI: Exception('There are not enough arguments given for <function update at 0x29cade8> of <ovirt.node.config.defaults.KDump object at 0x3f3ba50>',) Press ENTER to logout ... or enter 's' to drop to shell 2. After re-login, the error configuration of kdump is still saved in TUI. So the bug is not fixed in rhev-hypervisor6-6.5-20131031.1. Change the status from ON_QA to ASSIGNED.
A fix has been posted, and tested against current downstream images. It seems that the SSH key patches didn't make it, so we were passing too many arguments. It performs as expected with the new patch (no exception, values are cleared).

Test version: rhevh-6.5-20140110.1.iso ovirt-node-3.0.1-16.el6_5.noarch Test step: 1. Clear install rhevh-6.5-20140110.1.iso 2. Enter unreachable location in NFS type like "10:/". 3. Enter unreachable location in SSH type like "root@10". 4. Enter reachable location in SSH type like "root@10.66.1.1" without provide correct password. 5. E Test result: 1. After step2, it report an error and not save the error configuration in TUI adn /etc/kdump.conf. 2. After step3, it report an error and not save the error configuration in TUI adn /etc/kdump.conf. 3. After step4, it report an error and not save the error configuration in TUI adn /etc/kdump.conf. So this bug is fixed in rhevh-6.5-20140110.1.iso. Change the status from ON_QA to VERIFIED.
