我有一台小型 Debian 服务器，上面安装了 2 TB 的硬盘作为存储。Samba 服务器配置为使用此硬盘作为存储。
如果我想从我的 Windows 客户端复制一些大文件到 SMB 共享，Windows 会显示一条警告，提示该共享空间不足。
输出自df（/dev/sdb2 TB 磁盘）：

我的smb.conf：
[global]
workgroup = smb
security = user
map to guest = Bad Password
[homes]
comment = Home Directories
browsable = no
read only = no
create mode = 0750
[public]
path = /media/hdd/storage/
public = yes
writable = yes
comment = smb share
printable = no
guest ok = yes
force user = nobody
force group = nogroup
create mask = 777
directory mask = 777
SMB 运行时没有任何权限或用户限制（小型家庭服务器，我是唯一的用户）。
为什么 Windows 告诉我 SMB 空间不足？
