Description henrik.nordstrom 1999-11-08 04:30:16 EST
fdisk does not tell the kernel to reread the partition table
on changes to a BSD label (BSD labels is required by the
aboot loader).

As a work-around I use the attached program, or reboot the

int main(int argc, char **argv)
  int fd;

  fd = open(argv[1],O_RDONLY);
  errno = 0;
  return errno;

This is normal and expected behavior for a busy device - you can not invalidate

The device IS NOT BUSY!

fdisk does not even ask the kernel to reread the partition table when modifying
a BSD label.
Comment 3 henrik.nordstrom 2000-02-18 04:17:59 EST
BSD labels are accessed by entering b at the fdisk main menu prompt, which
causes fdisk to switch mode to BSD labels instead of DOS labels.

The same problem is also available in the minlabel utility (specific utility
only for BSD labels).
Comment 4 henrik.nordstrom 2000-02-18 04:19:59 EST
Forgot to mention the versions currently tested:

# rpm -q -f /sbin/fdisk /sbin/minlabel

This has been fixed in util-linux for quite a while.
