This may be in the documentation. If so, I missed it.
If a site has multiple Lustre file systems, the documentation implies that there only needs to be a single MGS for an entire site (regardless of the number of file systems). However, I also know it is fairly common to have a combined MGS/MDT. So here are the questions. 1. If we are going to have several Lustre file systems, is there any reason not to create each one with its own combined MGS/MDT? 2. Can an MGS which is a combined MGS/MDT for one file system serve as the MGS for one or more other file systems where the MGS and MDT are separate? 3. Is there any reason why doing several separate combined MGS/MDTs (one for each file system) won't work? What are other sites w/ multiple Lustre file systems doing? A dedicated MGS seems like a costly option.
