systemd-shutdown卡住，无法重启

**【标题描述】能够简要描述问题：**
1、服务器使用了软RAID组成的RAID1作为系统盘
2、系统盘分区使用了lvm卷；
3、灌装系统完成后，执行reboot命令，重启卡主，无法重启！
**一、缺陷信息**

**内核信息：**
5.10.0-136.55.0.134.oe2203sp1.x86_64
**缺陷归属组件：**
systemd
**缺陷归属的版本：**

**缺陷简述：**
1、服务器使用了软RAID组成的RAID1作为系统盘
2、系统盘分区使用了lvm卷；
3、灌装系统完成后，执行reboot命令，重启卡主，无法重启！
4、上图所示为reboot过程中卡主的进程的栈信息，以及lsof -p pid的信息；

经过对比，社区的发布版本ISO，默认文件系统ext4，不会存在reboot卡主的问题；当文件系统为xfs时，必现此问题！

**【环境信息】**
硬件信息
- 裸机场景请提供问题的硬件信息
- 虚拟机场景请提供虚拟机的XML文件或配置信息
软件信息
- OS版本及分支信息
- 内核信息
- 发现问题的组件版本信息
网络信息
- 如果有特殊组网，请提供网络拓扑信息
