[Users] How is it possible to increase disk size?

[ovirt at qip.ru]

each disk of VM on ISCSI SD is lv on vg of storage domain and thin provision disk size is maximum size that lv can expand

I created VM with thin provision disk 30Gb, on SPM lvs show actual size of disk 1Gb

if i do vdsClient extendVolume to 40Gb, lv size become 40Gb (but disk is thin provision and 40Gb is maximum not actual), but  webadmin and  engine cli show that disk size is not changed and is 30Gb

then i tried to update disk size using engine cli  "update  disk --size" and got following

[oVirt shell (connected)]# update disk Fedora17_Disk1 --size 42949672960
