[Starlingx-discuss] a question about starlingx error handling behavior

[Wang, Yi C]

Hi Eric,

Thank you, Eric! I will collect all the information and get back to you soon.

I confirm that I physically pulled the cable.

Thanks.

Please perform both cases and for each

-         indicate what cables/interfaces were pulled

-         indicate what hosts the cables were pulled from

-         indicate approximate timestamp of when the cable was pulled

-         indicate approximate timestamp of when the cable was reinserted

-         Run 'collect all' and provide me access to the collect tarball

Also, just to be sure ... please confirm that you are physically pulling the cable and not just ifdowning the interface.

Eric.

Hi Eric,

I am working on the LP 1815513<https://bugs.launchpad.net/starlingx/+bug/1815513>. Based on my tests, if I unplug the cable of active controller for management network for a long time (for example, 30s), and then plug it, the whole system can recover after some reboots. But if I unplug the cable for a short time, and then plug it. The whole system can't recover. I need to lock/unlock controllers manually to bring the system back. So my questions are:

1. Is the behavior acceptable? (recover the system by manual lock/unlock operations)
2. If the answer is no for #1, we need the system to recover automatically. I am not familiar with internal maintenance logics, could you give me some hints?

Thanks.
Yi
