Hi. I have 2012R2 cluster configured for CAU in self-updating mode with both WindowsUpdate and Hotfix plugins. The configuration went fine, however when I try to run CAU using these options, it will fail with the error "The plug-in argument HotfixRootFolderPath has invalid value".
I've repeatedly checked that the path is correct and browsable and has all the correct permissions it should have. I've tried with both DisableAclChecks True/False, didn't make a difference. The path contains a space, so I've tried enclosing it in double-quotes, that didn't help either.
I've ran CAU from the GUI, here's the command it generates:
Invoke-CauRun -ClusterName cluster01 -CauPluginName 'Microsoft.WindowsUpdatePlugin','Microsoft.HotfixPlugin' -CauPluginArguments @{ 'HotfixConfigFileName' = 'DefaultHotfixConfig.xml'; 'DisableAclChecks' = 'False'; 'HotfixRootFolderPath' = '\\fileserver\CAU\Windows Server 2012 R2\Hotfixes\Hyper-V\Root'; 'IncludeRecommendedUpdates' = 'True'; 'RequireSmbEncryption' = 'True' } -MaxFailedNodes -1 -MaxRetriesPerNode 3 -EnableFirewallRules -FailbackMode Immediate -Force
The root folder contains DefaultHotfixConfig.xml per documentation and also there's CAUHotfix_All folder (currently empty as there are no hotfixes I need to install).
As I've said above, I tried modifying the path in the command above to 'HotfixRootFolderPath' = '"\\fileserver\CAU\Windows Server 2012 R2\Hotfixes\Hyper-V\Root"', which didn't help.
Any idea what's wrong?
