视频大数据结果不更新原因多种，其中一种是ftp上传失败导致。排查时，首先查看结果，看在哪台服务器上。
然后运行一下mount指令，查看是否有挂载的网盘变为RO属性。
[root@localhost hisense]# mount

然后重新挂载变为RO的网盘。
[root@localhost hisense]# umount /dev/sde
[root@localhost hisense]# mount /dev/sde /data1
[root@localhost hisense]# umount /dev/sdf
[root@localhost hisense]# mount /dev/sdf /data2
[root@localhost hisense]# umount /dev/sdg
[root@localhost hisense]# mount /dev/sdg /data3
[root@localhost hisense]# umount /dev/sdh
[root@localhost hisense]# mount /dev/sdh /data4
[root@localhost hisense]# umount 172.23.6.73:/data/hisense/video
[root@localhost hisense]# umount /dev/sdd
umount: /data：目标忙。
(有些情况下通过 lsof(8) 或 fuser(1) 可以
找到有关使用该设备的进程的有用信息)
对于出现无法umount的网盘，先查看下哪个进程在使用这个盘。
[root@localhost hisense]# fuser -m /dev/sdd
/dev/sdd: 32306c
然后使用下面命令杀死占用网盘的进程。
[root@localhost hisense]# fuser -mk /dev/sdd
/dev/sdd: 32306c
最后重新挂载上即可。
[root@localhost ~]# umount /dev/sdd
[root@localhost ~]# mount /dev/sdd /data
