[pve-devel] [PATCH v2 manager 2/2] pvesr: prepare local job: remove stale replicated volumes immediately

[Fabian Ebner]

Commit 0433b86df6dfdf1d64ee09322719a02a91690707 introduced a
regression where only stale replicated volumes with an older
timestamp would be cleaned up. This meant that after removing a volume
from the guest config, it would only be cleaned up the second time the
replication ran afterwards. And the volume could become completely
orphaned in case the relevant storage wasn't used by the job anymore.

Dependency bump for libpve-guest-common >= 4.0-3 needed for
is_replication_snapshot().

Changes from v1:
    * Adapt to changed behavior of prepare() so we still only catch
      volumes that had replication snapshots belonging to the job.
