マウントエラーで方言が指定されていません。autofs/ Fedora 26でvers = 1.0を設定する場合、Drobo FS

私たちは4.13.9カーネルとNISでFedora 26を使用しており、 デフォルトのCIFS/Sambaバージョンは現在3. である問題を認識しています。ただし、私たちは古いDrobo FSを使用しています。これは、サポートがSMBバージョン1.0でのみ機能することを示しています。Droboを_/etc/fstab_ブート時に失敗することがあるので、autofs/automountを使用します。実行するcronジョブがあり、_/etc/auto.cifs_を呼び出す必要があります。以下の構成ファイルの内容に注意してください。可能な限り_vers=1.0_考えてみてください。以下の_ypcat -k_コマンドの結果は、オプションがmountコマンドに渡されていないように見えることを示しています。設定ファイルがどこかにないのですか？_/etc_ mountまたはCIFSのすべての出現を検索しますが、コメント以外は返されません。おそらく、私には明らかではないが、これを読んでいる誰かのためのものである可能性があります。

# Automagically mount CIFS shares in the network, similar to

# Put a line like the following in /etc/auto.master:
# /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.

vers=1.0オプションを追加する場所を見つけました。プライマリNISサーバーには、各キャンパスの両方のDroboユニット用のファイルがいくつかあります。

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

しかし、私を逃れたもう1つのことは、上記のファイルに変更を加えた後にmake -C /var/ypを実行する必要があり、NISドメイン内の他のワークステーション/サーバーが変更を確認し始めたことです。

cifs-utilsのドキュメントへの変更、およびsetcifsaclの小さなバグ修正 も変更されました。
