Hi,
what is the client's behavior if NFS3ERR_BAD_COOKIE is replied by
READDIRPLUS3 ?
I have this error when running bonnie++ on top of my (non knfsd) server.
At this step bonnie++ readdirs all dentries and erase them. One of the
readdir calls ends with NFS3ERR_BAD_COOKIE and immediatly after, the
client is calling RMDIR3, without having removed any of the found
dentries. Of course RMDIR3 replies NFS3ERR_NOT_EMPTY, but I do not
understand why REMOVE is not called. It looks like the clients behaves
that the directory is empty after having received NFS3ERR_BAD_COOKIE
(that just an hypothesis, I am not just this is what actually happens).
Do you have any idea ?
Regards
Philippe

Thanks for your reply, Trond.
No, it does not. It uses the readdir() call that takes a directory as
argument and returns a pointer to an array of struct dirents.
When bad cookie is sent back to the application, which error will it be.
I saw errno = 523 ? Is this correct ?
