如何在 2008 上使用 Powershell 配置集群共享的权限?

如何在 2008 上使用 Powershell 配置集群共享的权限?

我有一个“文件共享”类型的集群资源,但是当我尝试配置“安全”参数时出现以下错误(摘录):

Set-ClusterParameter : Parameter 'security' does not exist on the cluster object

使用 cluster.exe 时,我得到了更好的结果,即命令生效时通常没有任何结果。但是当我在故障转移群集管理器中检查时,权限没有改变。在 Server 2003 中,cluster.exe 方法有效。

有任何想法吗?

整个命令和错误。

我找到了一个简单易用且显而易见的答案。它非常简单,以至于人们可能不相信这是微软的解决方案。

$permissions 是一个权限数组,包含一个帐户(domain\user)、一个权限(fullcontrol)和一个类型(allow)。

# create access rule based on permissions
$rule = new-object system.security.accesscontrol.filesystemaccessrule $permissions

# get an acl, remove access rules, add our rule
$acl = get-acl "c:\" # need to get acl from root of drive to avoid inheritance
$acl.access | foreach-object {$acl.removeaccessrule($_)}
$acl.setaccessrule($rule)

# get security descriptor from acl and convert to binary security descriptor
$sddl = $acl.sddl
$sdhelper = [wmiclass]"win32_securitydescriptorhelper"
$binarysd = ($sdhelper.sddltobinarysd($sddl)).binarysd

# get cluster resources from registry
$resources = get-childitem "hklm:\cluster\resources"

# ...with paths that powershell will understand
$resources = $resources | foreach-object {$_.pspath}

# find clustershare resource path
$resource = $resources | where-object {(get-itemproperty $_ name).name -eq $clustershare}

# derive path to resource parameters
$parameters = "$resource\parameters"

# configure security descriptor
set-itemproperty $parameters "security descriptor" $binarysd

真的就这么简单。

唯一的问题是,这只适用于一个节点,并且必须在每个节点上重复执行。它确实在故障转移后仍然存在(并且当共享故障恢复到节点时,节点上设置的权限将重新出现)。此外,它仅适用于“完全控制”,而不适用于“读取”或其他权限。不知道为什么。

我不会接受这个答案,因为它确实不是。但它似乎是最接近于这个问题的解决方案,在 Windows Server 2003 中根本不存在(cluster.exe 可以设置共享权限),而且微软似乎没有在任何地方解决这个问题。
