In lustre you MUST have a MGS _AND_ MDS node and an associated MDT (file system) running on the MDS. Typically the MDS and MGS are configured on the same node.

Need some guidance on getting past this error that I get mounting the OST on the Client. This is the first time I am trying to mount it so not sure what I could be missing.. I will be glad to provide any other logs that would be helpful to determine the root
cause of this issue..<o:p></o:p></div>
