Moving VM's from datastores
One ESXi host with 2 raid cards (identical) and a raid array on each.
One is the new one, one is the old one. It hosts a single guest which I need to move from one to the other.
Copying one of the virtual disks over (which is 1.2TB) is HORRENDOUSLY slow. As in, it's currently got 50 hours remaining.
These aren't particularly slow drives, RAID10 arrays on both.
That's just a standard copy operation from within the GUI. I don't particularly want to risk using vmkfstools in SSH to do it with the reports of it timing out for large files for so many people, plus I don't trust the thick/thin provisioning properties of it.
Is there a quicker way to do it? Starting to think restoring from backup would be far faster!
