Description

Observation

openQA test in scenario sle-12-SP4-Server-DVD-aarch64-extra_tests_in_textmode@aarch64 fails in
mdadm

The only two runs where the mdadm module is included and the test could reach this step both fail because the system is heavily loaded.
This load results in commands timing out because they cannot return to a shell in time.

Reproducible

Fails since mdadm module was added to the test schedule

Expected result

Test does not fail because it is written in a way that it can handle stalled consoles until mdadm finishes its operations

Further details

Always latest result in this scenario: latest

easy solution for now would be to exclude the test module because it never worked -> which removes the urgency of the ticket

I've checked the last executions of the 'mdadm' module on SLE12 SP4, and noticed that in 6 runs there are no fails with the symptoms from the description of the ticket.

The 'mdadm' module failed once in 0387 build, but due to another reason (missing import 'use version_utils 'is_sle';'). Also, it passes for SLE15 all the time.

So, my suggestion is to monitor the module for several builds more and see if it needs to be modified.

I've executed 10 jobs: https://openqa.suse.de/tests/overview?distri=sle&version=12-SP4&build=poo40394_mdadm_investigation&groupid=132

After they are finish, I'll investigate the statistics of passes/fails.

'mdadm' module is passed in all the 10 jobs. So, I'm closing the ticket as the issue is not reproducible anymore.
