Subject: [PATCH 25/52] imsm: block changing slots during creation
|
|
|
fdf7c0 |
|
|
|
fdf7c0 |
If user specifies drives for array creation, then slot order across
|
|
|
fdf7c0 |
volumes is not preserved.
|
|
|
fdf7c0 |
Ideally, it should be checked in validate_geometry() but it is not
|
|
|
fdf7c0 |
possible in current implementation (order is determined later).
|
|
|
fdf7c0 |
Add verification in add_to_super_imsm_volume() and throw error if
|
|
|
fdf7c0 |
mismatch is detected.
|
|
|
fdf7c0 |
IMSM allows to use only same members within container.
|
|
|
fdf7c0 |
This is not hardware dependency but metadata limitation.
|
|
|
fdf7c0 |
Therefore, 09-imsm-overlap test is removed. Testing it is pointless.
|
|
|
fdf7c0 |
After this patch, creation in this scenario is blocked. Offset
|
|
|
fdf7c0 |
verification is covered in other tests.
