我们正在使用带有 4.13.9 内核和 NIS 的 Fedora 26，并且我意识到了默认 CIFS/Samba 版本现在为 3.0。但是我们使用较旧的 Drobo FS，他们的支持人员说它仅适用于 SMB 版本 1.0。我们没有安装 Drobo，/etc/fstab因为它有时会在启动时失败，因此我们使用 autofs/automount。我们有一个正在运行的 cron 作业，应该会调用/etc/auto.cifs并记录以下配置文件的内容。我添加了vers=1.0所有我能想到的地方。下面的命令结果ypcat -k显示选项似乎没有传递给mount命令。我是否在某个地方缺少配置文件？我已经 grep 了所有内容/etc以查找所有出现的mount或 CIFS，但除了注释之外什么都没有返回。也许我遗漏了一些对我来说并不明显但可能对阅读本文的人来说很明显的东西......
cat /etc/auto.cifs

# Note: create a cred file for each windows/Samba-Server in your network

# user account name or password.

下面是：

# This file must be executable to work! chmod 755!
# Automagically mount CIFS shares in the network, similar to

# /cifs /etc/auto.smb --timeout=300
# You'll be able to access Windows and Samba shares in your network
# under /cifs/host.domain/share
# "smbclient -L" is used to obtain a list of shares from the given host.
# In some environments, this requires valid credentials.
# This script knows 2 methods to obtain credentials:
# 1) if a credentials file (see mount.cifs(8)) is present
# under /etc/creds/$key, use it.
# 2) Otherwise, try to find a usable kerberos credentials cache
# for the uid of the user that was first to trigger the mount
# and use that.
# If both methods fail, the script will try to obtain the list
# of shares anonymously.

但是在运行时：

答案1
我找到了添加vers=1.0选项的位置。在主 NIS 服务器上，我们为每个校园的两个 Drobo 单元提供了几个文件：
cat /etc/auto.drobo-uptown
drobo-downtown -fstype=cifs,vers=1.0,rw,user,suid,credentials=/etc/auto.smb.drobo-uptown ://drobo-uptown/drobo-downtown
但是另一件让我困惑的事情是，我必须make -C /var/yp在对上述文件进行更改后运行，然后 NIS 域中的其他工作站/服务器才能开始看到更改。
