Subject: [PATCH 41/53] libparted/dasd: correct the offset where the first
|
||
|
|
partition begins
|
||
|
|
|
||
|
|
The start point of first partition must start at least from the third
|
||
|
|
track of DASD, due to the existence of metadata in the first two track.
|
||
|
|
The previous constraint just sets all the device to be partitioned.
|
||
|
|
So when the start point of the first partition start before the third
|
||
|
|
track, (For example if it starts from.0) parted will exit abruptly.
|
||
|
|
And this kind of job must be done with constraint explicitly.
|
||
|
|
|
||
|
|
Then the constraint is modified to exclude the first two tracks and
|
||
|
|
to make the first partition start from the third track by default.
