Hi,

i have some Virtual machines running on an OCFS2 volume. 
That means that their disk images reside on an OCFS2 volume.
I needed to change something inside one vm and created a relink of it before.
What i wanted to change went wrong. I need the reflink.

I have vm.raw and vm_before_configure.raw.
vm_before_configure.raw is my reflink.
The files are quite big: 280 GB.

My planned procedure is:
Stop Virtual machine.
Copy vm_before_configure.raw somewhere else to vm_before_configure.raw.bak.
Delete or rename vm.raw
Rename vm_before_config.raw.bak to vm.raw
Start the VM again.
Hopefully be happy.

Is that ok ?

Bernd
