I've created a snapshot of a VM <br>with an OS and data disk before upgrading the machine.<br><div><br></div>The upgrade went fine and I now want to remove the snapshot. <br>Unfortunately this fails with the error:<br><div><br></div>"Cannot remove Snapshot. Low disk space on target Storage Domain <br>stadius-virt2_PERC."<br><div><br></div>So I can't free disk space by removing the snapshot because I don't have <br>enough space?<br><div><br></div>When I look at the VM the disks are shown as preallocated (which is what <br>I selected during installation). When I look at the storage tab and list <br>the disks in my storage domain, the disks are now shown as thin <br>provisioned with the actual size > virtual size.<br><div><br></div>How can I remove this snapshot? I don't have enough free disk space in <br>my storage domain to duplicate the data disk of my VM.<br><div><br></div>Regards,<br><div><br></div>Rik<br><div><br></div><br>-- <br>Rik Theys<br>System Engineer<br>KU Leuven - Dept.
