From: mike Subject: [NFS] Back to basics - still having NFS issues Date: Wed, 30 Apr 2008 22:36:00 -0700 Message-ID: Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" To: nfs@lists.sourceforge.net Return-path: Received: from neil.brown.name ([220.233.11.133]:49808 "EHLO neil.brown.name" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1752590AbYEAFgM (ORCPT ); Thu, 1 May 2008 01:36:12 -0400 Received: from brown by neil.brown.name with local (Exim 4.63) (envelope-from ) id 1JrRSj-0002v9-4I for linux-nfs@vger.kernel.org; Thu, 01 May 2008 15:36:09 +1000 Sender: linux-nfs-owner@vger.kernel.org List-ID: I've switched up my setup now, thinking this would "mature" it more. Everything is gigabit ethernet. Server: FreeBSD 7.0, quad-core xeon 3220, 2GB RAM, 4x750 hardware RAID10 Adaptec 3405 (so ~ 1.5TB usable) 42 processes: 1 running, 41 sleeping CPU states: 0.0% user, 0.0% nice, 0.5% system, 0.0% interrupt, 99.5% idle Mem: 15M Active, 1581M Inact, 325M Wired, 48M Cache, 214M Buf, 9232K Free Swap: 2048M Total, 20K Used, 2048M Free /etc/rc.conf: nfs_server_flags="-u -t -n 16" /etc/exports: /home -maproot=root -network 10.13.5.0 -mask 255.255.255.0 Clients (3 moderate usage, 2 minimal usage): Linux 2.6.24-16-server, quad-core xeon 3220, 4GB RAM, single SATA2 250G disk (barely used) /etc/fstab: raid01:/home /home nfs rsize=8192,rsize=8192,tcp,rw,acregmin=30 I stuck with the 8k since it seems like FreeBSD (from what I read) recommended it. It seems damn near rock solid but one machine consistently flakes out (and is identical in every way - hardware, fstab, nfs-common parameters, etc) to two other nodes that don't show any issues (and I think are stable, for the most part...) I get those nasty: [26792.279141] nfs: server raid01 not responding, still trying [26792.279172] nfs: server raid01 not responding, still trying [26792.279201] nfs: server raid01 not responding, still trying [26792.279231] nfs: server raid01 not responding, still trying [26792.279261] nfs: server raid01 not responding, still trying [26792.279293] nfs: server raid01 not responding, still trying [26792.908086] nfs: server raid01 not responding, still trying [26798.780814] nfs: server raid01 not responding, still trying [27151.795931] nfs: server raid01 OK [27151.796477] nfs: server raid01 OK [27151.797130] nfs: server raid01 OK [27151.797287] nfs: server raid01 OK [27151.797382] nfs: server raid01 OK [27151.798190] nfs: server raid01 OK [27151.798237] nfs: server raid01 OK [27151.798282] nfs: server raid01 OK [27151.798484] nfs: server raid01 OK But it takes a while for it to recover, meanwhile the client is useless...
