When a user logs on they request a mount from the server. Where is that mount? Is it physically copied to the client or are bits of it it NFS'd from the server each time he does something with it or is there a link to it on his machine. . .? We've been getting some very slow progress just recently, with open office under kde and especially as the file count grows on the server.
The files are 'NFS'd' to the client as demanded - effectively. NFS can get very slow if the directories have very high file counts (at least, I've notices the same effect on directories will 1000+ files.) It may also depend on the filesystem you are exporting. You could try using the async export option (see man exports)
Yeah. That's what I thought. Each user has over 1000+ files before they have done any work under kde. All these have to be pulled in from the server I expect.
Well, only the directory info for each unless a file is opened.
Will try the async tomorrow. BTW we moved from ext3 to reiser over the summer. I wish I'd never done that.
In my experience that is a Bad Move when it comes to NFS
Do you mean the asnyc or the reiser. I think you mean the latter..I'm stuck with it until our next downtime at Xmas.
I mean the Reiser - all the 'issues' are supposed to be dealt with, but when I wan using Reiser and nfs (both from 8.2) I had endless trouble with speen and failed mounts which simply vanished when I went to ext3.
Anything else I might try? I've been toying with the idea of losing the daisy-chain switches and putting up a nic for each switch instead. Would each nic on the server have the same IP?
No, in fact each would have to be on a separate subnet as well as a separate IP, unless you did some nifty routing setup.
May this improve the NFS throughput?
Quite possibly - since the network layer would be able to handle (theoretically) four times the traffic (having four connections to use). The nfs server itself would only run at the same rate. Dylan -- Sweet moderation Heart of this nation Desert us not We are between the wars - Billy Bragg
