[SOLVED] Thin provisioning: can i enable it later?

[fireon]

Hello,

i'am using Proxmox4 with ZFS.
i have an ZFS Storagemodel https://pve.proxmox.com/wiki/Storage:_ZFS#Adding_a_ZFS_storage_via_GUI without Thin provisioning. I would like to enable it yet, but have some vm's already runnig on. So it is this an problem? Or can i enable it for me without any problem? I know, Thin provisioning should only work for new vm's that i add.

Thanks and best Regards

yes. It is just a flag passed to 'zfs create'

I know, Thin provisioning should only work for new vm's that i add.
