Subject: [PATCH 25/61] imsm: block changing slots during creation
|
|
Patch-mainline: mdadm-4.2+
|
|
References: jsc#PED-1009
|
|
|
|
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.
