我在导入大型 tarball 时服务器崩溃了k3s ctr images import my_image.tar。重启服务器并尝试重新导入后，出现以下错误：

unpacking docker.io/library/my_image (sha256:b69c6d6ebdb9517f7a93deede3ccf6380aebbc6a8fa68da14ab06bc1be131423)...ctr: failed to prepare extraction snapshot "extract-774071004-6PJT sha256:6e98c2a3f1228e003bc43b054a526b4bf36783f2ff04b8b6ce12b0beb640555d": failed to stat parent: stat /var/lib/rancher/k3s/agent/containerd/io.containerd.snapshotter.v1.overlayfs/snapshots/327/fs: no such file or directory: unknown

327缺少目录。如果我运行k3s ctr snapshots tree它，它会显示：

...

我尝试删除最后两张快照：

我尝试过修剪图像，k3s ctr images prune --all但没有帮助。有没有办法在不重新安装 containerd 的情况下解决这个问题？

更新

在我删除/var/lib/rancher/k3s/agent/containerd目录并重新导入所有图像后，问题就解决了。
