Over Intel this does not happen. When I run exportfs -a on the server when the clients have already mounted their nfs filesystem, the kernel exports table as can be seen from /proc/fs/nfs/exports gets completely flushed out. We (me and one another colleague) have done some digging (mostly looking into nfsutils codebase) and it looks like a kernel side issue. We had also asked folks in the linux-mips mailing list, but apparently no one has any clue. I am just hoping that those who are more familiar with the user level and kernel side of nfs might me something more to chew on. If you can give any suggestions that will be really useful. If you think the information I provided is not enough, I can give you any other information you need in this regard. We are using mips SB1 64 bit processor and running a 2.6.17 kernel from linux-mips.org. Thanks in advance, Ani
