Subject: [PATCH 25/52] imsm: block changing slots during creation |
|
|
|
If user specifies drives for array creation, then slot order across |
|
volumes is not preserved. |
|
Ideally, it should be checked in validate_geometry() but it is not |
|
possible in current implementation (order is determined later). |
|
Add verification in add_to_super_imsm_volume() and throw error if |
|
mismatch is detected. |
|
IMSM allows to use only same members within container. |
|
This is not hardware dependency but metadata limitation. |
|
Therefore, 09-imsm-overlap test is removed. Testing it is pointless. |
|
After this patch, creation in this scenario is blocked. Offset |
|
verification is covered in other tests. |
