Gentoo NAS - NFS Oddity ???

System: Dual AMD64, 3GB RAM, 1Gb LAN, 2.5TB 3Ware 9000 SATA Raid Array.

O/S: Gentoo Linux running with Vanilla 2.6.8.1 kernel (BCM5700 Network Card Patch) including nfs-utils 1.0.6 r4.

The oddity I am seeing is that when under stress over NFS it becomes unaccessible and will not work without rebooting, I don't see anything that relates to it other than this (not actually sure what this is):

previously we have been using Slackware to do the job with no problems any ideas?

I've seen quite abit of posts on the web relating to high-usage NFS
- all of them are problematic. All suggested to move on to something elso - samba.
I believe linux.com(net?) had a good discussion on this topic, sorry can't look it up right now

Aye I've seen this also, wierd thing is I only recently started getting these wierd scenarios since installing Gentoo.

It's definately something to do with NFS in particular rpc.statd but I can't work out what.

a couple of posts suggest that the permissions of /var/lib/nfs/shm and /var/lib/nfs/shm.bak need to be writeable to the user running rpc.statd which when using OOB Gentoo it's Nobody?!

Also something associated with POSIX locking.

Thing about our setup is that we use alot of HPUX, Solaris and RHEL3.0 don't ask Corporate decision, But I designed this system using Gentoo for the 64Bit generation of NAS and it's not performing as good as the 32Bit NAS running Slackware.

I just can't work out this wierd error, we use alot of NIS and Automounter at this site as we have alot of NAS systems and keeping track is an arse.

I have now downloaded nfs-utils version 1.0.3 from sourceforge and the error has gone.

The version of nfs-utils being made available on portage doesn't work properly.
