[Lustre-discuss] Lustre - usage / best practices

[Jon Yeargers]

I’ll soon be retiring a number of old file servers and have the opportunity to move to a DFS based system. Im wondering about using Lustre for ‘mixed purposes’ and what the recommended setup is.

More specifically: lets say there are three groups that want to use the space. One group is primarily storing Tb of data in large numbers of flat files. A second group is using a DB like MySQL that has fewer but larger files. A third may have some other process. Would I divide up my DFS space somehow or is it ok for all three groups to comingle? Would I do something on the Lustre clients to force them apart or just rely on Linux security to restrict access to the client folders (on the lustre client)?

I can imagine creating a single Lustre client and then NIS mounting the various volumes on separate machines for each group. This seems like adding an extra step but perhaps it’s the normal pattern?
