Subject: [pve-devel] [RFC guest-common 09/13] vzdump: schema: add fleecing property string
Date: Thu, 25 Jan 2024 15:41:45 +0100 [thread overview]
Message-ID: <20240125144149.216064-10-f.ebner@proxmox.com> (raw)
In-Reply-To: <20240125144149.216064-1-f.ebner@proxmox.com>
It's a property string, because that avoids having an implicit
"enabled" as part of a 'fleecing-storage' property. And there likely
will be more options in the future, e.g. threshold/limit for the
fleecing image size.
