[replication.pm] Subject: [pve-devel] [PATCH guest-common 1/2] replication: prepare: include volumes without snapshots in the result X-BeenThere: pve-devel@lists.proxmox.com X-Mailman-Version: 2.1.29 Precedence: list List-Id: Proxmox VE development discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 20 Jan 2023 10:18:36 -0000 Note that PVE::Storage::volume_snapshot_info() will fail when a volume does not exist, so no non-existing volume will end up in the result (prepare() is only called with volumes that should exist). This makes it possible to detect a volume without snapshots in the result of prepare(), and as a consequence, replication will now also fail early in a situation where source and remote volume both exist, but (at least) one of them doesn't have any snapshots. Such a situation can happen, for example, by deleting and re-creating a volume with the same name on the source side without running replication after deletion.
