Currently the teardown doesn't care about destroy other lxc containers and destroys everything. Same for logical volumes in the lxc volume group. This tweaks the message to make it more clear. Closes-Bug: #1518492 Change-Id: If8bbd9c8b6cea4d18ad982ee676e0480a88a1a4e

WARNING: This is a destructive action.
|
|
All containers will be destroyed as well as the data within the
|
|
containers (even if the containers are added by users and not by
|
|
AIO). Data will be removed from the host as well (e.g. files, apt
|
|
packages and pip packages). Please check this script for information
|
|
about the data to be removed in removed_(files/packages/pip-packages).
|
|
/etc/openstack_deploy will be preserved and may be manually removed
|
|
if needed.
|
|
ALL the data stored in the lvm volume group called "lxc" WILL BE
|
|
DELETED as well (even if volumes are created by users and not AIO).
|
|
Please verify that you have backed up all important data prior to
|
|
proceeding with the teardown script.
