Description of problem:

The lvm2app library reports the stripe size of volumes
incorrectly.


~# lvs --version
  LVM version:     2.02.98(2) (2012-10-15)
  Library version: 1.02.77 (2012-10-15)
  Driver version:  4.23.0


For example if I create a volume with 2 stripes of 128k:

~# lvcreate -i 2 -I 128 --extents 100  vg1
  Logical volume "lvol0" created


The lvs command gets it right:

~# lvs -o +stripe_size
  LV    VG   Attr      LSize   Pool Data%  Move Log Copy%  Convert Stripe
  lvol0 vg1  -wi-a---- 100.00m                                     128.00k



However, the number from the library is as follows:

     value = lvm_lvseg_get_property(lvm_lvseg, "stripesize");
     if (value.is_valid)
        qDebug() << "Stripe size: " << value.value.integer;

Result:
  Stripe size:  256


The library seems to be reporting the number of sectors since
256 * 512 = 131072 bytes which is 128k.

The error occures with any stripe size;
