Hi,
Can you please provide more details?
1) Origin domain type.
2) Destination domain type & size.
3) Was VM up or not? Live Migration?
4) Engine logs if you have.

Thanks!

Pavel

Dear Users,

I have exactly same problem.
When I trying to migrate a big (16 TB) disk image to an another storage domain, i've got this error message:

Error while executing action: Cannot move Virtual Disk. Low disk space on Storage Domain Backup.


But I have a lot of space...

Ovirt 4.3.7

Please help me what can I do?

Regards,

Tibor

Assunto: Re: [ovirt-users] Low disk space on Storage

This was fixed in 4.3.6, I suggest upgrading
