[ovirt-users] Extended ovirt image disk and now virtual size is < 1 GiB and actual size i +1TB

Hi, i extended 16 virtual image disks today by 1000GiB through the GUI and now we have a problem with some of them... 9 of them are shown if "edited" that they have a size of 0GiB and not 16360GiB as expected? 5 of them are not able to be extended either within the VM. we tried to power it off and then on again (not reboot, but actual power off / power on) any suggestions to get out of this weird mode? disks seems as if they have the "old" size within the VM but are shown in oVirt as if they are 0GiB.? They are relying on a posix compliant fs if that makes any difference, and they are thin-provisioned and discard-enabled. Thanks in advance.
