file-permissions - NFS configuration for write-once read-many access

Question

Is there a way to replicate the write-once read-many capability of NetApp's SnapLock using a standard Linux NFS server?

I've considered using inotify to chmod files as they're written to the server, but is there a simple way to do this, or a way that would also allow anonymous writes? (All the NFS clients are on a secure network, so that would save extra client-side configuration.)

如果您的意思是“我可以在没有 NetApp 存储的情况下做 SnapLock 的工作吗”，答案是“不”。NetApp SnapLock 使用 NetApp WAFL 文件系统的特定功能，以及防止欺骗服务器系统时间的防篡改合规时钟（提前设置时间，以便您可以删除尚未过期的内容）。

如果您的意思是“我可以使用 NFS 命令锁定 NetApp SnapLock 卷上的文件吗”，答案是“可以”。SnapLock 功能旨在与 NFS 和 CIFS 文件命令一起使用。
