Re: nfs options

["Cheryl L. Southard" <cld astro caltech edu>]

Hi Derek,

We've been seeing this issue since June when we upgraded the kernel and 
nfs-utils modules on our RHEL WS 3 Update 2 computers.  Processes on 10 of our
linux clients will lock up trying to read files via NFS from our solaris
mail server.

What seems to help is if we add "rsize=8192,wsize=8192" to our options
in /etc/fstab.  So now the /etc/fstab line for our solaris:/var/mail line
looks like this on our linux client:

solaris:/var/mail        /var/spool/mail nfs     rsize=8192,wsize=8192   0 0

Now, I think 8192 is way too small and we can go as high as 32768, but I
haven't tested out that number yet.

Hope this helps.

Cheryl
