I frequently use my hot-spare MDT machine for brief testing with a client. Usually when we have scheduled outages. I wouldn't rely on it for a day to day thing, but for testing to see if everything is working properly after patches, outages, upgrades, etc it seems to work fine. I've used the main once or twice but tend to cross my fingers the entire time.
This has worked since about ~1.[6|7]? Definitely in 1.8 Still working today on the 2.5.x main.

OSTs and MDTs can coexist, and I believe OSTs and Clients can coexist relatively peacefully, but MDTs and Clients are a bad mix. -Ben Evans -----Original Message----- From: lustre-discuss [mailto:[email protected]] On Behalf Of Lukas Hejtmanek Sent: Thursday, May 21, 2015 7:34 AM To: [email protected] 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? -- Lukáš Hejtmánek _______________________________________________ lustre-discuss mailing list [email protected] http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org _______________________________________________ lustre-discuss mailing list [email protected] http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org _______________________________________________ lustre-discuss mailing list [email protected] http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
