Title:
'Socket /var/run/openvswitch/ovnnb_db.sock not found' during ovn_start
Status in devstack:
Fix Released
Status in neutron:
Invalid
Bug description:
This is the same as bug 1942697 [1] and I'm opening a new bug per
comment #2.
I've seen this in the gate occasionally, ovn fails to start because a
socket file it expects is not present. Here's an example trace [2]:
