Samba server settings

Samba server settings-general Linux technology-Linux technology and application information. For details, refer to the following section. I have set the write list = liuhongming permission to access/fringe write on the samba server and changed/fringe to write permission.
However, after the client loads the directory as user liuhongming, it cannot add a new folder or file [root @ localhost mnt] # mkdir 112333
Mkdir: the directory "112333" cannot be created: Input/Output Error
However, I changed the server write list to writable and set it to yes. There is no problem in adding a new directory to the client. Please kindly advise. I am a newbie in cainiao.
