How does /proc/fs/nfs/exports compair with /etc/exports when this happens... Sorry I forgot to check this. I will let you know as soon as the problem occurs again. As you might have understood it is an intermittent problem, so I can't tell you when this will be ;) . By the way, shouldn't you assign the bug to yourself?

Missed this at first, but /data/inout which seems exported in /proc/fs/nfs/exports on athlon above is not actually mounted on pentium.

Do exports that are forcedly unmounted survive a reboot?? |
