[check_vdo]
# Title:              None
# Reason:             Confirmation
# ============================= check_vdo.confirm =============================
# Label:              Are all VDO devices, if any, successfully converted to LVM management?
# Description:        Enter True if no VDO devices are present on the system or all VDO devices on the system have been successfully converted to LVM management. Entering True will circumvent check of failures and undetermined devices. Recognized VDO devices that have not been converted to LVM management can still block the upgrade despite the answer.All VDO devices must be converted to LVM management before upgrading.
# Reason:             To maximize safety all block devices on a system that meet the criteria as possible VDO devices are checked to verify that, if VDOs, they have been converted to LVM management. If the devices are not converted and the upgrade proceeds the data on unconverted VDO devices will be inaccessible. In order to perform checking the 'vdo' package must be installed. If the 'vdo' package is not installed and there are any doubts the 'vdo' package should be installed and the upgrade process re-run to check for unconverted VDO devices. If the check of any device fails for any reason an upgrade inhibiting report is generated. This may be problematic if devices are dynamically removed from the system subsequent to having been identified during device discovery. If it is certain that all VDO devices have been successfully converted to LVM management this dialog may be answered in the affirmative which will circumvent block device checking.
