Right.
Well. We need to somehow get the maximum length a partition can be in the file.
If we do get this information, I suspect start, end here are sector
numbers.. we can do that rather easily. Note that in the file below,
sdb is being used.. not a file yet. It is just my local testing thing
which will add a partition properly. Unfortunately we need to make
start and end with the right
values. I've seen Gemetry.getMaxGeometry I think in the text you sent..
but after trying to get some geometry or a maximum start and end
sector a partition can be
I have still not been able to come up with the right function. The
code below will add a partition though.
#!/usr/bin/python
import os
import sys
import parted
device = parted.Device(path="/dev/sdb")
disk = parted.Disk(device=device)
start = 1
end =
new_geom = parted.Geometry(device=device,
start=start,
end=end)
partition = parted.Partition(disk=disk,
type=82,
geometry=new_geom)
constraint = parted.Constraint(exactGeom=new_geom)
disk.addPartition(partition=partition,
constraint=constraint)
disk.commit()
