</span><span lang="EN-US" style="font-family:"Arial",sans-serif;mso-fareast-language:EN-US">But we decided to separate the linux-io-Cluster from the Windows client only cluster, because of security requirements and ssh management requirements. We can use at
this point, local named admins on Windows and use on Linux a Deamon and an separated Admin-interface Network for pwless root ssh. Your Hint seems to be CCR related or is this a Cygwin problem.

entirely Linux and that solved it. If this is not an option, perhaps adding some Linux nodes to your remote cluster as quorum nodes would help.<o:p></o:p></span></p>
