Created attachment 1242104 [details] ovirt-engine log Description of problem: We're trying to copy a template to one of our Storage Domains, which space utilization is: Total: 500GB Used: 384GB Free: 115GB Problem is when we hit the Copy button on the template's disk and select this SD as the destination, it complains about not having enough space to copy it. The template's disk is 20GB long in size. The step that seems to fail is the validation: 2017-01-18 09:37:29,948 WARN [org.ovirt.engine.core.bll.storage.disk.MoveOrCopyDiskCommand] (default task-186) [523db857] Validation of action 'MoveOrCopyDisk' failed for user admin@internal.

Low disk space on Storage Domain XXX.] The SD domain is iSCSI-based. I'm attaching the ovirt-engine log from the moment we try to copy the template to the moment it fails. Version-Release number of selected component (if applicable): 4.0.4.4 How reproducible: Always Steps to Reproduce: 1. Go to the Template tab 2. Choose one of the templates 3. Click on the Disks sub-tab and choose the disk to copy 4. Click on "Copy" 5. Select XXX as destination Storage Backend Actual results: An "Operation Cancelled" popup is shown with this error message: Error while executing action: Cannot copy Virtual Disk. Low disk space on Storage Domain XXX.
Tal, could you please take a look?
As a side note: I can move VM's disks to DS XXX, it's only a *template* disk I cannot.
Few updates: - The issue is that the calculated space that for the copy disk on the target domain is the template disk size X the number of already existing copies. For example: If we have a template disk 10 GB and I copied it to 7 storage domains and now I want to copy it to 8th storage domain with 50 GB free space, the calculated size for the copy disk will be 70 GB.
Copied a 10G template disk from source domain that had 36G allocated size. The template disk was already copied on 9 storage domains. The destination domain free space was 44G. Copy disk was initiated and completed successfully. Tested using: rhevm-4.1.1.3-0.1.el7.noarch
