查看卷名方法：切换到终端获取ROOT权限后：DF    #查看卷名命令
方法能用：sa6400万能能机型支持NVME，
插件添加：在运行引导的时候点CONFIG进入配置菜单，添加cpuinfo插件、hdddb插件、nvmesystem插件、nvme cache插件。

方法一：采用脚本。
下载TARGZ文件：
https://github.com/007revad/Synology_HDD_db/releases/tag/v3.5.105
解压这个文件，上传到NAS某一个目录里面
SSH登陆NAS
sudo -i                                    #获取ROOT权限
cd /volume1/xiayao//HDD_db/  #进入目录
chmod +x syno_hdd_db.sh    #给sh脚本最高权限
./syno_hdd_db.sh -fr    #运行脚本不检查兼容性。
reboot   #重启NAS

NAS中加入计划任务，设置触发事件，用户ROOT，命令符为：
/volume1/xiayao//HDD_db/syno_hdd_db.sh

方法二：强行格式化硬盘为BRFS目录
SSH登陆NAS
sudo -i                                    #获取ROOT权限

ls /dev/nvme*                         #查看NVME名称
/dev/nvme0  /dev/nvme0n1  /dev/nvme0n1p1  /dev/nvme0n1p2  /dev/nvme0n1p3  /dev/nvme0n1p4
