Comment 4 Rajesh Tailor 2020-10-09 12:10:17 UTC

Hello

Could you provide following information.

1) Did the minor update completed successfully for all compute nodes including source and destination ?
2) When did you created the instance, before starting the minor update or before update converge step (during minor update) as mentioned in BZ description ?
3) Did you see similar issue for other compute nodes in the environment or is the issue occur for some compute nodes ?


I looked into the attached logs but couldn't find anything obvious yet. 
Could you please also attach undercloud logs as well  and /var/lib/kolla content from overcloud compute nodes ?

Hi Rajesh,

Thank you for your help.

1) Did the minor update completed successfully for all compute nodes including source and destination ?
=> yes

2) When did you created the instance, before starting the minor update or before update converge step (during minor update) as mentioned in BZ description ?
=> The failed live-migration instances were created before minor update.
the instances that created after converge step are working normally with live migration.

3) Did you see similar issue for other compute nodes in the environment or is the issue occur for some compute nodes ?
=> They created test lab, and the same issue is occurring in it.

Could you please also attach undercloud logs as well  and /var/lib/kolla content from overcloud compute nodes ?
=>
I'll ask to them.

Thank you,
Regards,
YoungCheol.

Hi, 

we have reproduced the issue and identified the root cause.
For more details on the root cause check [1].

I'll close this BZ as a duplicate of 1888951.
