action #122773: [qe-core][leap 15.4 update]test fails in cifs,failed to rollback to the snapshot - openQA Tests - openSUSE Project Management Tool

Hmmm, what could trigger this is that the consoles between the last snapshot and the current test run differs. The test fails at select_serial_terminal(): https://openqa.opensuse.org/tests/3030786#step/cifs/3

# Test died: Failed to wait for login prompt at opensuse/lib/serial_terminal.pm line 137.

The snapshot was taken while the test was in the root-console: https://openqa.opensuse.org/tests/3030786#step/consoletest_setup/67

Looking into this.

I see almost all test runs failing. This is a good starting point to test my hypothesis, that the issue arises from using a different console in the snapshot point and in the restore point.

The console was not the issue, the test run is still failing: https://duck-norris.qe.suse.de/tests/11878#

However it's not failing, if the root-console was selected instead of the serial terminal: https://duck-norris.qe.suse.de/tests/11875#

Nope, also switching to root-console before the snapshot rollback is not really helping: https://duck-norris.qe.suse.de/tests/11879#step/cifs/2

Ok, I'm out of luck with the easy stuff. Now going to advance to do some more dirty work here. First attempt: Increase all relevant timeouts and check if this is just a timeout issue.

This might get ugly though.

So it's likely also not a timeout issue: https://duck-norris.qe.suse.de/tests/11881#step/cifs/3 (failure after increasing the timeout from 90 to 300 seconds).
