[lustre-discuss] Coexistence of Luster client and server on a single machine

[Ben Evans]

I believe it is OK for some simple functional testing, but not production, or working with large datasets. 

OSTs and MDTs can coexist, and I believe OSTs and Clients can coexist relatively peacefully, but MDTs and Clients are a bad mix.

Subject: [lustre-discuss] Coexistence of Luster client and server on a single machine

Hello,

some time ago I asked whether it is possible to run lustre server (OSD) and client (mount -t lustre) on the same machine. Somewhere close to Lustre 1.3.x, the answer was not, such setup is not recommended due to VM pressure from client and server.

Is there anything new with current mainline Lustre version? So, can I mount my lustre fs on the same server that is used as OSD or MTS without harm?
