[Lustre-discuss] Does Lustre require Linux as the client

[Lustre-discuss] Does Lustre require Linux as the client
I did a quick test exporting the LustreFS via NFS. It seemed painfully slow. MB/min rather than MB/s. I did not, in retrospect play around with the mount options (like w/rsize). I know NFS exporting is not yet optimised, but has anybody else found NFS too slow to be usable? Or did I just mess up the test? (again!)

I hope these are not dumb questions...Very good questions, in fact. I hope the answers are encouraging. Thanks-- -Phil

There are two or three other pieces of low-hanging fruit which will eventually be implemented, but without a customer for this work, it is not top priority. People have reported that Samba exports are substantially faster than NFS with Lustre 1.0.x, if that''s of interest to you. Hope that helps-- -Phil

[Lustre-discuss] Does Lustre require Linux as the client
Trying to ramp up on Lustre and have a few basic questions. 1) Does a Linux client require anything installed to access/mount a Lustre file system? 2) Can the client be a MS Win 2000 machine? 3) If the client requires something installed to access the Lustre FS, could that client be a Samba server which exports the FS to a Win2000 client? 4) Can a Lustre FS be exported via NFS so other NFS clients can mount it? My intent is to give Win2000 PC''s access to the Lustre filesystem without installing anything on them. I hope these are not dumb questions... Thanks DSP
