Hello!

We've got Hyper-V 2012r2 and CentOS 6.6 running in VM.

We have web-server running on it. And in fact it uses space:

df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg_bitrix2-lv_root
                       50G  3,7G   43G   8% /
tmpfs                 1,9G     0  1,9G   0% /dev/shm
/dev/sda1             477M   46M  406M  11% /boot
/dev/mapper/vg_bitrix2-lv_home
                      439G  101G  316G  25% /home

But vmdk file in Hyper-V weights 300Gb.

I tried 

cd / ; cat /dev/zero > zero.fill ; sync ; sleep 1 ; sync ; rm -f zero.fill

And after that:

Mount-VHD 'D:\Hyper-V\bitrix2\Virtual Hard Disks\bitrix2.vhdx' -ReadOnly
Optimize-Vhd -path 'D:\Hyper-V\bitrix2\Virtual Hard Disks\bitrix2.vhdx' -Mode Full
Dismount-VHD 'D:\Hyper-V\bitrix2\Virtual Hard Disks\bitrix2.vhdx'

But it doesn't help..Can anyone help us with the problem?
