调整容器磁盘大小后，重启，再重新 df 看，磁盘大小未变。查了下资源，还需使用 resize2fs 实施变更即可：sudo resize2fs /dev/rbd1

参考 How to Grow an ext2/3/4 File System with resize2fs。

容器挂载的 rbd ，启动时报错：

MountVolume.MountDevice failed for volume "xx" : rbd: failed to mount device /dev/rbd5 at /var/lib/k8s/kubelet/plugins/kubernetes.io/rbd/rbd/xx (fstype: ext4), error 'fsck' found errors on device /dev/rbd5 but could not correct them: fsck from util-linux 2.23.2 /dev/rbd5: recovering journal /dev/rbd5 contains a file system with errors, check forced. /dev/rbd5: Resize inode not valid. /dev/rbd5: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY. (i.e., without -a or -p options) .

执行： sudo e2fsck -f /dev/rbd5 即可，不过由于文件系统已报错，数据会丢失。
