Snapshot removal (merge) includes a create volume phase. This volume is temporary and gets removed once the snapshot merge is completed. Its size is the size of the disk. That means that in order to remove the snapshot, the storage domain should have available size that is equal to the disk size.

Hi, I'm running the ovirt engine 3.4 series. I've created a snapshot of a VM with an OS and data disk before upgrading the machine. The upgrade went fine and I now want to remove the snapshot. Unfortunately this fails with the error: "Cannot remove Snapshot. Low disk space on target Storage Domain stadius-virt2_PERC." So I can't free disk space by removing the snapshot because I don't have enough space? When I look at the VM the disks are shown as preallocated (which is what I selected during installation). When I look at the storage tab and list the disks in my storage domain, the disks are now shown as thin provisioned with the actual size > virtual size. How can I remove this snapshot? I don't have enough free disk space in my storage domain to duplicate the data disk of my VM. Regards, Rik -- Rik Theys System Engineer KU Leuven - Dept.
