[ovirt-users] Low disk space on Storage

Hi, I'm running ovirt Version:4.3.4.3-1.el7 My filesystem disk has 30 GB free space. Cannot start a VM due to an I/O error storage. When tryng to move the disk to another storage domain get this error: Error while executing action: Cannot move Virtual Disk. Low disk space on Storage Domain DATA4. The sum of pre-allocated disk is the total of the storage domain disk. Any idea what can I do to move a disk to other storage domain? Many thanks -- Jose Ferradeira http://www.logicworks.pt
