Subject Re: Troubleshooting virtual router failing to start
Date Fri, 13 Dec 2019 11:25:57 GMT
Greg,

what does it mean "***Recently***, we downgraded back to 4.9.3 to re-run
the processes" - have you created a lot of new resources with the upgraded
env (4.11 code) and then restored the DB to 4.9.3 ? If so, you need to
delete ALL (I mean all) resources you might have created - any VMs, VRs,
volumes, networks (i.e. bridges or similar) etc, otherwise you will hit all
kind of issues when ACS 4.9.3 tries to create volumes/VMs of the same name,
create bridges/vnets of the same name etc (which already exist due to being
created by 4.11)

Rolling back after some time running the new code/creating new resources is
a challenge to handle - and NOT recommended by all means.

Best,
Andrija
