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.
