I noted this as an independent bug.
Three separate issues here:
1) Wizard cannot take UUID names as names too long but does not note
character limit that would guide one not to do that :)
2) Wizard , as it should, allows you to assign devices independently for
each server, but does not retain this table on creation of ansible table.
3) Wizard, even when ansible file modified to reflect /dev/sd# for each
server, ignores this and runs against drive NOT called for in ansible file.
See attached Logs from where I took wizard output.. corrected first server
which is to use /dev/sdc vs servers 2,3 to use /dev/sdb and deployment
is against /dev/sdb on ALL THREE nodes.
# Ansible file used per bug where it defines drives incorrectly to be just
ID of first node

I have three drives in each server. The first is a 512GB SSD and this is
how I want to do initial HCI setup. The other six are bricks with existing
data VDO volumes from old Glutster volume. I wanted to import those. But
lafter a few attempts it became apparent the HCI wizard just can't figure
out how to stop VDO / Create partitions etc... and ignore drives not within
its script. I have backups so I wiped all the data back to nakid
drives..well.. then had other issues with CentOS that I am working out...
so delay until I root cause that Hmmmm.. issue.
Thanks for input/help

Hey!
I am guessing that the deployment is failing due to the long lv name.
Can you try to edit the ansible-playbook and shorten the lv name to 55
characters and try again?
