Hi all,

Since PVE9, we have Volume Chain Snapshotting. The documentation states: 
'Enabling or disabling this flag only affects newly created virtual disk 
volumes.’

Two questions:
1: Are there plans to make it possible to convert existing LVM Backed 
storages with images that already exist? Or is there an idea how we can 
convert existing images?
2: Why is this in status ’Technology Preview’? What are the risks that 
are in the back of the heads of the developers? Or is it mainly ’there 
might be bugs, but we expect dataconsistency to be OK’?

Thanks,
