Comment 10 for bug 1844363

I am now able to reproduce this issue.
2020-05-22_20-00-00

$ system host-list
+----+--------------+-------------+----------------+-------------+--------------+
| id | hostname | personality | administrative | operational | availability |
+----+--------------+-------------+----------------+-------------+--------------+
| 1 | controller-0 | controller | unlocked | enabled | available |
| 2 | compute-2 | worker | unlocked | enabled | available |
| 3 | compute-1 | worker | unlocked | enabled | available |
| 4 | storage-0 | storage | unlocked | enabled | available |
| 5 | compute-0 | worker | unlocked | enabled | available |
| 6 | storage-1 | storage | unlocked | enabled | available |
| 7 | controller-1 | controller | unlocked | enabled | available

1. Created 2 partitions (one 11 the other 9 size_gb) using the disk on conroller-1

$ system host-disk-partition-list controller-1
+--------------------------------------+-----------------------------+----------------+--------------------------------------+----------+-------+--------+
| uuid | device_path | device_node | type_guid | type_nam | size_ | status |

| | 86:00.0-nvme-1-part2 | | | Physical | | |
| | | | | Volume | | |
| | | | | | |

The size_gib reduced down to 352.609 as expected.

2. Then perform wipedisk operation here

[sysadmin@controller-1 ~(keystone_admin)]$ system host-disk-wipe controller-1 b30e85dd-cf52-43a9-986c-e07249473703
WARNING: This operation is irreversible and all data on the specified disk will be lost.
Continue [yes/N]: yes
None

Check that the available_gib returnes to ~372

| | | | | |

3. Confirm that the inventory updates the partition list

Result

Long after the wipedisk operation, the 1st partition created (of the 2) still has not been removed from the inventory.
