Description Vincent S. Cojot 2021-10-05 17:28:21 UTC 
Description of problem:

When running the OVS to OVN migration on 16.2
https://access.redhat.com/documentation/en/red_hat_openstack_platform/16.2/html/networking_with_open_virtual_network/migrating-ml2ovs-to-ovn#ml2-ovs-to-ovn-migration-prepare_migrating-ml2ovs-to-ovn
(step 10), the ovn_migration script aborts with this error:

[stack@osp16d ~]$ ovn_migration.sh setup-mtu-t1   | sudo tee -a /var/log/ovn_migration_output.txt
OVN t-h-t environment file seems to be missing in /home/stack/OSP/osp16.2/bin/deploy_ovn_small.sh. Please check the /home/stack/OSP/osp16.2/bin/deploy_ovn_small.sh file again.


But the file is referenced by the answers file.

The deploy script is:
$ cat /home/stack/OSP/osp16.2/bin/deploy_ovn_small.sh
#!/bin/bash
#
#
[ "$BASH" ] && function whence
{
        type -p "$@"
}
#
ret=0
#
export PATH_SCRIPT="$(cd $(/usr/bin/dirname $(whence -- $0 || echo $0));pwd)"
export TOP_DIR="$(cd ${PATH_SCRIPT}/..; pwd)"
export TRIPLEO_DIR="/usr/share/openstack-tripleo-heat-templates"

source ${TOP_DIR}/pre_deploy.sh || exit 127
set -x
time openstack overcloud deploy \
--templates \
-r ${TOP_DIR}/roles_data.yaml \
-n ${TOP_DIR}/network_data.yaml \
-e ${TOP_DIR}/node_info_small.yaml \
--answers-file ${TOP_DIR}/answers-file-ovn.yaml \ <=============================
"$@"
ret=$(($ret + $?))


The answers file includes the proper t-h-t template:
