[Xen-devel] linux-2.4.29-xenU and blockdev --getss

[Pasi Kärkkäinen <pasik@xxxxxx>]

Hi!

When I run blockdev --getss on Xen 2.0 Linux-2.4.29-xenU I get this:

$ blockdev --getss /dev/sda4
-1

Why sectorsize is not 512?

$ blockdev --getsize /dev/sda4
2097152

The size of sda4 is 1 GB, so the sectorsize has to be 512.

xenU sda4 is lvm-volume in dom0. 

blockdev on dom0:

$ blockdev --getss /dev/vg0/swap_sda4
512

$ blockdev --getsize /dev/vg0/swap_sda4
2097152

I'm asking this because I'm having problem using loopback-mounts in xenU
using those sd-devices.. mount/loop calculates the device size two times too
big.. and that of course causes problems when trying to access the
non-existing second-half of the loopback-mounted sda4-device.
