Subject: [pve-devel] [PATCH v2 guest-common 1/3] replication: prepare: include volumes without snapshots in the result
Date: Wed, 13 Dec 2023 15:17:45 +0100 [thread overview]
Message-ID: <20231213141747.679613-2-f.ebner@proxmox.com> (raw)
In-Reply-To: <20231213141747.679613-1-f.ebner@proxmox.com>
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.
