Subject: [PATCH 09/12] imsm: Write empty PPL header if assembling |
|
regular clean array. |
|
|
|
If array was initially assembled with kernel without PPL support - |
|
initial header was never written to the drive. |
|
If initial resync was completed and system is rebooted to kernel with |
|
PPL support - mdadm prevents from assembling normal clean array |
|
due to lack of valid PPL. |
|
Write empty header when assemble normal clean array, so the |
|
its assamble is no longer blocked. |
