Guys,
I had a look at the latest version of libparted. Here also in function
ped_disk_new(), disk->needs_clobber is set to 0 after type->ops->read(disk).
Why do we want to keep need_clobber set to 1 while reading the partition table
? I think needs_clobber should be set to 0 before partition table is read.
Please see the code below:
PedDisk*
ped_disk_new (PedDevice* dev)
{
..
..
disk = ped_disk_new_fresh (dev, type);
if (!disk)
goto error_close_dev;
<-- disk->needs_clobber should be
set to 0 here.
if (!type->ops->read (disk))
goto error_destroy_disk;
disk->needs_clobber = 0;
..
..
}
gpt_read() tries to correct the partition table in case primary or secondary is
corrupted. If needs_clobber is set, gpt_read() will try to clobber the
partition table signatures which is incorrect (in case write_back is set).
Why do we need to remove other partition table signatures while reading a
partition table ?
thanks,
rahul
