What gives you

kpartx -l /dev/VG_XenStorage-7b010600-3920-5526-b3ec-6f7b0f610f3c/lv_snapshot

?

This should list you the partitions contained in your LV. Only thoose partitions should be mounted.

Hai,

I use following steps for LV backup.

                            lvcreate -L 5G -s -n lv_snapshot /dev/VG_XenStorage-7b010600-3920-5526-b3ec-6f7b0f610f3c/VHD-a2db885c-9ad0-46c3-b2c3-a30cb71d83f8
                            lv_snapshot created

This command worked properly
Then issue kpartx command

                         kpartx -av /dev/VG_XenStorage-7b010600-3920-5526-b3ec-6f7b0f610f3c/lv_snapshot

But this command not return any value.
                         vgscan
Reading all physical volumes. This may take a while...
