deployment stuck at 100% all nodes ready

[Andrey Epifanov]

Our steps:
- perform the following command:
  fuel --env <cluster ID> deployment --delete
- added 4 new compute nodes (these nodes were already used before) to the already deployed env before (cluster)
- network verify (failed) ?! for the 3 nodes which were in cluster
- pushed deploy changes
- nodes were deployed 100% and marked as ready
  all tasks complete 100%
- deployment stuck and the env didn't go to the operational state

Workaround:
- deleted all tasks
- env still is not in operational state
- Openstack works fine

Env:
MOS: Mirantis Openstack::5.1.1.
OS: Centos
Reference architecture: -
Networking: Neutron::Neutron with GRE

Andrey, please attach diagnostic snapshot.

[Ihor Kalnytskyi (ikalnytskyi)]

Move it to Incomplete until diagnostic snapshot is attached.

[Miroslav Anashkin (manashkin)]

Attached some logs.
Full snapshot is about 300 Gib.

[Vitaly Sedelnik (vsedelnik)]

Invalid for 5.1.1-updates because with 5.1.1 maint updates we could deliver OpenStack fixes only but not deployment time fixes.

[Sergii Golovatiuk (sgolovatiuk)]

Bug is valid but won't be fixed due to low priority
