Re: Broken NFS (perhaps Cache invalidation bug ?)

I should have added the kernel: 2.6.9-22.0.2.ELsmp #1 SMP with nfs-utils-1.0.6-65.EL4

I have a problem which appears to be very similar to a cache invalidation bug previously reported: http://www.ussg.iu.edu/hypermail/linux/kernel/0510.1/0582.html

With a conventional nfs mount (not automount), c0-0 a client node, running on the nfs server:

echo 10 > Probe
ssh -x c0-0 cat Probe
echo 11 > Probe
ssh -x c0-0 cat Probe

Will give, most times, 10 & 10 rather than 10 & 11.

I've tried a wide range of things (including consulting local experts), so far nothing. I'm not a kernel developer, so please be gentle. This problem has occurred ever since we moved to the 4.X releases of rocks (http://www.rocksclusters.org), X=0 or 1 although it's hidden by their default use of automounting and it's taken some time to reduce it to something simple.
